VirtualBox is free virtualization software that allows us home users to play with multiple operating systems within our main computer. By creating a virtual machine, we can run guest software, i. You could run Linux within Windows or the other way round.

We can also use different versions of Linux within Linux or Windows within Windows. Virtualization is massive right now. It allows individuals and enterprises to run several functions on a single computer, rather than forcing someone to find the space and the money to have more than one. So rather than building a separate computer to run a different operating system, you only need one. At an enterprise level, rather than running a backup server, a separate mail server, and a separate SharePoint server, each can run in its own virtual instance on a single physical host machine.

Two terms you need to learn right away to be able to work with VirtualBox are host and guest. Guest refers to the operating system you will be running within the box.

For instance, if you want to run Linux within Windows, then Windows would be the host and Linux would be the guest. VirtualBox is free and fairly simple to use. However, there are a few configuration tricks you will need to know in order to get the best out of it. If this option is not set either, then UTF-8 is used. This option specifies the character set used for the shared folder name. This is UTF-8 by default. The generic mount options, documented in the mount manual page, apply also. For example:.

Oracle VM VirtualBox provides the option to mount shared folders automatically. When automatic mounting is enabled for a shared folder, the Guest Additions service will mount it for you automatically.

For Linux or Oracle Solaris, a mount point directory can also be specified. If a drive letter or mount point is not specified, or is in use already, an alternative location is found by the Guest Additions service. The service searches for an alternative location depending on the guest OS, as follows:. Search for a free drive letter, starting at Z:. If all drive letters are assigned, the folder is not mounted.

Linux and Oracle Solaris guests. Access to an automatically mounted shared folder is granted to everyone in a Windows guest, including the guest user. For Linux and Oracle Solaris guests, access is restricted to members of the group vboxsf and the root user. Oracle VM VirtualBox enables you to drag and drop content from the host to the guest, and vice versa. For this to work the latest version of the Guest Additions must be installed on the guest.

Drag and drop transparently allows copying or opening files, directories, and even certain clipboard formats from one end to the other. For example, from the host to the guest or from the guest to the host. You then can perform drag and drop operations between the host and a VM, as it would be a native drag and drop operation on the host OS. At the moment drag and drop is implemented for Windows-based and X-Windows-based systems, both on the host and guest side.

In the context of using drag and drop, the origin of the data is called the source. That is, where the actual data comes from and is specified. The destination specifies where the data from the source should go to. Transferring data from the source to the destination can be done in various ways, such as copying, moving, or linking. At the moment only copying of data is supported.

Moving or linking is not yet implemented. When transferring data from the host to the guest OS, the host in this case is the source, whereas the guest OS is the destination. However, when transferring data from the guest OS to the host, the guest OS this time became the source and the host is the destination. For security reasons drag and drop can be configured at runtime on a per-VM basis either using the Drag and Drop menu item in the Devices menu of the virtual machine, as shown below, or the VBoxManage command.

Disables the drag and drop feature entirely. This is the default when creating a new VM. Host To Guest. Enables drag and drop operations from the host to the guest only. Guest To Host. Enables drag and drop operations from the guest to the host only.

Enables drag and drop operations in both directions: from the host to the guest, and from the guest to the host. Drag and drop support depends on the frontend being used. At the moment, only the VirtualBox Manager frontend provides this functionality.

The modifyvm and controlvm commands enable setting of a VM’s current drag and drop mode from the command line. As Oracle VM VirtualBox can run on a variety of host operating systems and also supports a wide range of guests, certain data formats must be translated after transfer. This is so that the destination operating system, which receives the data, is able to handle them in an appropriate manner.

When dragging files no data conversion is done in any way. For example, when transferring a file from a Linux guest to a Windows host the Linux-specific line endings are not converted to Windows line endings. Plain text: From applications such as text editors, internet browsers and terminal windows. Directories: For directories, the same formats apply as for files.

If you start Oracle VM VirtualBox with Administrator privileges then drag and drop will not work with Windows Explorer, which runs with regular user privileges by default. On Linux hosts and guests, programs can query for drag and drop data while the drag operation is still in progress. This currently is not supported. As a workaround, a different file manager, such as Nautilus, can be used instead. This works for all supported host platforms, provided that your host operating system can make use of your accelerated 3D hardware in the first place.

It is only available for certain Windows, Linux, and Oracle Solaris guests. In particular:. OpenGL on Linux requires kernel 2. Ubuntu As a result, the Guest Additions installation program offers Direct3D acceleration as an option that must be explicitly enabled. Also, you must install the Guest Additions in Safe Mode. Because 3D support is still experimental at this time, it is disabled by default and must be manually enabled in the VM settings.

Untrusted guest systems should not be allowed to use the 3D acceleration features of Oracle VM VirtualBox, just as untrusted host software should not be allowed to use 3D acceleration. Drivers for 3D hardware are generally too complex to be made properly secure and any software which is allowed to access them may be able to compromise the operating system running them. In addition, enabling 3D acceleration gives the guest direct access to a large body of additional program code in the Oracle VM VirtualBox host process which it might conceivably be able to use to crash the virtual machine.

The Aero theme is not enabled by default on Windows. See your Windows platform documentation for details of how to enable the Aero theme. This driver acts as a hardware 3D driver and reports to the guest operating system that the virtual hardware is capable of 3D hardware acceleration. When an application in the guest then requests hardware acceleration through the OpenGL or Direct3D programming interfaces, these are sent to the host through a special communication tunnel implemented by Oracle VM VirtualBox.

The host then performs the requested 3D operation using the host’s programming interfaces. With this feature, if an application such as a video player inside your Windows VM uses 2D video overlays to play a movie clip, then Oracle VM VirtualBox will attempt to use your host’s video acceleration hardware instead of performing overlay stretching and color conversion in software, which would be slow.

This currently works for Windows, Linux and Mac OS X host platforms, provided that your host operating system can make use of 2D video acceleration in the first place. Because 2D support is still experimental at this time, it is disabled by default and must be manually enabled in the VM settings.

The driver sends all overlay commands to the host through a special communication tunnel implemented by Oracle VM VirtualBox. On the host side, OpenGL is then used to implement color space transformation and scaling. With the seamless windows feature of Oracle VM VirtualBox, you can have the windows that are displayed within a virtual machine appear side by side next to the windows of your host. This feature is supported for the following guest operating systems, provided that the Guest Additions are installed:.

After seamless windows are enabled, Oracle VM VirtualBox suppresses the display of the desktop background of your guest, allowing you to run the windows of your guest operating system seamlessly next to the windows of your host. The Host key is normally the right control key. This will enlarge the size of the VM’s display to the size of your host screen and mask out the guest operating system’s background.

This provides the following advantages:. For example, to monitor VM performance and statistics. Arbitrary string data can be exchanged between guest and host. This works in both directions. To accomplish this, Oracle VM VirtualBox establishes a private communication channel between the Oracle VM VirtualBox Guest Additions and the host, and software on both sides can use this channel to exchange string data for arbitrary purposes.

Guest properties are simply string keys to which a value is attached. They can be set, or written to, by either the host and the guest. They can also be read from both sides. In addition to establishing the general mechanism of reading and writing values, a set of predefined guest properties is automatically maintained by the Oracle VM VirtualBox Guest Additions to allow for retrieving interesting guest data such as the guest’s exact operating system and service pack level, the installed version of the Guest Additions, users that are currently logged into the guest OS, network statistics and more.

Some of this runtime information is shown when you select Session Information Dialog from a virtual machine’s Machine menu. A more flexible way to use this channel is with the VBoxManage guestproperty command.

For example, to have all the available guest properties for a given running VM listed with their respective values, use this command:.

To query the value of a single property, use the get subcommand as follows:. To add or change guest properties from the guest, use the tool VBoxControl. This tool is included in the Guest Additions. When started from a Linux guest, this tool requires root privileges for security reasons. The Guest Control File Manager is a feature of the Guest Additions that enables easy copying and moving of files between a guest and the host system.

Other file management operations provide support to create new folders and to rename or delete files. The Guest Control File Manager works by mounting the host file system.

Guest users must authenticate and create a guest session before they can transfer files. At the bottom of the Guest Control File Manager, enter authentication credentials for a user on the guest system. Transfer files between the guest and the host system by using the move and copy file transfer icons. You can copy and move files from a guest to the host system or from the host system to the guest. Click Close to end the guest session.

The Guest Additions enable starting of applications inside a guest VM from the host system. This feature can be used to automate deployment of software within the guest. For this to work, the application needs to be installed on the guest. No additional software needs to be installed on the host. Additionally, text mode output to stdout and stderr can be shown on the host for further processing.

There are options to specify user credentials and a timeout value, in milliseconds, to limit the time the application is able to run. The Guest Additions for Windows allow for automatic updating. This applies for already installed Guest Additions versions. Also, copying files from host to the guest as well as remotely creating guest directories is available.

In server environments with many VMs, the Guest Additions can be used to share physical host memory between several VMs. This reduces the total amount of memory in use by the VMs. If memory usage is the limiting factor and CPU resources are still available, this can help with running more VMs on each host.

The Guest Additions can change the amount of host memory that a VM uses, while the machine is running. Because of how this is implemented, this feature is called memory ballooning.

Oracle VM VirtualBox supports memory ballooning only on bit hosts. It is not supported on Mac OS X hosts. Memory ballooning does not work with large pages enabled. Normally, to change the amount of memory allocated to a virtual machine, you have to shut down the virtual machine entirely and modify its settings. With memory ballooning, memory that was allocated for a virtual machine can be given to another virtual machine without having to shut the machine down.

When memory ballooning is requested, the Oracle VM VirtualBox Guest Additions, which run inside the guest, allocate physical memory from the guest operating system on the kernel level and lock this memory down in the guest. This ensures that the guest will not use that memory any longer.

No guest applications can allocate it, and the guest kernel will not use it either. Oracle VM VirtualBox can then reuse this memory and give it to another virtual machine. The memory made available through the ballooning mechanism is only available for reuse by Oracle VM VirtualBox.

It is not returned as free memory to the host. Requesting balloon memory from a running guest will therefore not increase the amount of free, unallocated memory on the host. Effectively, memory ballooning is therefore a memory overcommitment mechanism for multiple virtual machines while they are running. This can be useful to temporarily start another machine, or in more complicated environments, for sophisticated memory management of many virtual machines that may be running in parallel depending on how memory is used by the guests.

At this time, memory ballooning is only supported through VBoxManage. Use the following command to increase or decrease the size of the memory balloon within a running virtual machine that has Guest Additions installed:. You can also set a default balloon that will automatically be requested from the VM every time after it has started up with the following command:.

By default, no balloon memory is allocated. This is a VM setting, like other modifyvm settings, and therefore can only be set while the machine is shut down. It avoids memory duplication between several similar running VMs. In a server environment running several similar VMs on the same host, lots of memory pages are identical. For example, if the VMs are using identical operating systems.

Page Fusion currently works only with Windows and later guests. The more similar the VMs on a given host are, the more efficiently Page Fusion can reduce the amount of host memory that is in use. It therefore works best if all VMs on a host run identical operating systems. Instead of having a complete copy of each operating system in each VM, Page Fusion identifies the identical memory pages in use by these operating systems and eliminates the duplicates, sharing host memory between several machines.

This is called deduplication. If a VM tries to modify a page that has been shared with other VMs, a new page is allocated again for that VM with a copy of the shared page. This is called copy on write. All this is fully transparent to the virtual machine. You may be familiar with this kind of memory overcommitment from other hypervisor products, which call this feature page sharing or same page merging. However, Page Fusion differs significantly from those other solutions, whose approaches have several drawbacks:.

Traditional hypervisors scan all guest memory and compute checksums, also called hashes, for every single memory page. Then, they look for pages with identical hashes and compare the entire content of those pages. If two pages produce the same hash, it is very likely that the pages are identical in content.

This process can take rather long, especially if the system is not idling. As a result, the additional memory only becomes available after a significant amount of time, such as hours or sometimes days.

It can therefore achieve most of the possible savings of page sharing almost immediately and with almost no overhead. Page Fusion is also much less likely to be confused by identical memory that it will eliminate, just to learn seconds later that the memory will now change and having to perform a highly expensive and often service-disrupting reallocation.

To enable Page Fusion for a VM, use the following command:. You can observe Page Fusion operation using some metrics. Enabling Page Fusion might indirectly increase the chances for malicious guests to successfully attack other VMs running on the same host. See Section The Guest Additions provide services for controlling the guest system’s monitor topology. The resolution of a virtual monitor can be modified from the host side either by resizing the window that hosts the virtual monitor, through the view menu or through VBoxManage controlvm “vmname” setscreenlayout.

The decision is made automatically at each desktop session start. Since the mentioned monitor topology control services are initialized during the desktop session start, it is impossible to control the monitor resolution of display managers such as gdm, lightdm. Please refer to Section 4. When this guest property is set then VBoxDRMClient is started during the guest OS boot and stays active all the time, for both ithe display manager login screen and the desktop session.

Specifically, disabling a guest monitor except the last one invalidates the monitor topology due to limitations in the Linux kernel module vmwgfx.

Note: After upgrading VirtualBox it is recommended to upgrade the guest additions as well. Failure to do this will cause a typical Windows installation to display multiple dialogs asking whether you want to install a particular driver.

On some Windows versions, such as Windows and Windows XP, the user intervention popups mentioned above are always displayed, even after importing the Oracle certificates. Installing the code signing certificates on a Windows guest can be done automatically.

Use the VBoxCertUtil. This command installs the certificates to the certificate store. When installing the same certificate more than once, an appropriate error will be displayed. To allow for completely unattended guest installations, you can specify a command line parameter to the install launcher:.

This automatically installs the right files and drivers for the corresponding platform, either bit or bit. By default on an unattended installation on a Vista or Windows 7 guest, there will be the XPDM graphics driver installed. Instead, the WDDM graphics driver needs to be installed.

This is only required for Vista and Windows 7. For more options regarding unattended guest installations, consult the command line help by using the command:.

If you would like to install the files and drivers manually, you can extract the files from the Windows Guest Additions setup as follows:. To explicitly extract the Windows Guest Additions for another platform than the current running one, such as bit files on a bit system, you must use the appropriate platform installer. Use VBoxWindowsAdditions-x The Guest Additions work in those distributions. You may choose to keep the distribution’s version of the Guest Additions but these are often not up to date and limited in functionality, so we recommend replacing them with the Guest Additions that come with Oracle VM VirtualBox.

The Oracle VM VirtualBox Linux Guest Additions installer tries to detect an existing installation and replace them but depending on how the distribution integrates the Guest Additions, this may require some manual interaction. It is highly recommended to take a snapshot of the virtual machine before replacing preinstalled Guest Additions. The Aero theme is not enabled by default on Windows. See your Windows platform documentation for details of how to enable the Aero theme.

In some cases, Windows 10 crashed and then booted into a black screen. I had to delete the VM, so be careful if you already invested some time in your installation. You had better create a snapshot before the installation. After I installed VirtualBox 4. However, the end result was essentially the same as with VirtualBox 4. A closer look at the crash revealed that the graphics driver is probably the culprit, which led me to the solution below.

To be on the safe side, you should disable it. To do so, right-click the VBoxWindowsAdditions-amd On the Compatibility tab, check Run this program in compatibility mode for and select Windows 7.

Virtualbox guest additions windows 10 64 bit.Setting Up Your 64-bit Guest in VirtualBox

 

This currently is not supported. As a workaround, a different file manager, such as Nautilus, can be used instead. This works for all supported host platforms, provided that your host operating system can make use of your accelerated 3D hardware in the first place.

It is only available for certain Windows, Linux, and Oracle Solaris guests. In particular:. OpenGL on Linux requires kernel 2. Ubuntu As a result, the Guest Additions installation program offers Direct3D acceleration as an option that must be explicitly enabled. Also, you must install the Guest Additions in Safe Mode. Because 3D support is still experimental at this time, it is disabled by default and must be manually enabled in the VM settings.

Untrusted guest systems should not be allowed to use the 3D acceleration features of Oracle VM VirtualBox, just as untrusted host software should not be allowed to use 3D acceleration. Drivers for 3D hardware are generally too complex to be made properly secure and any software which is allowed to access them may be able to compromise the operating system running them. In addition, enabling 3D acceleration gives the guest direct access to a large body of additional program code in the Oracle VM VirtualBox host process which it might conceivably be able to use to crash the virtual machine.

The Aero theme is not enabled by default on Windows. See your Windows platform documentation for details of how to enable the Aero theme. This driver acts as a hardware 3D driver and reports to the guest operating system that the virtual hardware is capable of 3D hardware acceleration. When an application in the guest then requests hardware acceleration through the OpenGL or Direct3D programming interfaces, these are sent to the host through a special communication tunnel implemented by Oracle VM VirtualBox.

The host then performs the requested 3D operation using the host’s programming interfaces. With this feature, if an application such as a video player inside your Windows VM uses 2D video overlays to play a movie clip, then Oracle VM VirtualBox will attempt to use your host’s video acceleration hardware instead of performing overlay stretching and color conversion in software, which would be slow. This currently works for Windows, Linux and Mac OS X host platforms, provided that your host operating system can make use of 2D video acceleration in the first place.

Because 2D support is still experimental at this time, it is disabled by default and must be manually enabled in the VM settings. The driver sends all overlay commands to the host through a special communication tunnel implemented by Oracle VM VirtualBox. On the host side, OpenGL is then used to implement color space transformation and scaling. With the seamless windows feature of Oracle VM VirtualBox, you can have the windows that are displayed within a virtual machine appear side by side next to the windows of your host.

This feature is supported for the following guest operating systems, provided that the Guest Additions are installed:.

After seamless windows are enabled, Oracle VM VirtualBox suppresses the display of the desktop background of your guest, allowing you to run the windows of your guest operating system seamlessly next to the windows of your host. The Host key is normally the right control key. This will enlarge the size of the VM’s display to the size of your host screen and mask out the guest operating system’s background.

This provides the following advantages:. For example, to monitor VM performance and statistics. Arbitrary string data can be exchanged between guest and host. This works in both directions. To accomplish this, Oracle VM VirtualBox establishes a private communication channel between the Oracle VM VirtualBox Guest Additions and the host, and software on both sides can use this channel to exchange string data for arbitrary purposes.

Guest properties are simply string keys to which a value is attached. They can be set, or written to, by either the host and the guest. They can also be read from both sides.

In addition to establishing the general mechanism of reading and writing values, a set of predefined guest properties is automatically maintained by the Oracle VM VirtualBox Guest Additions to allow for retrieving interesting guest data such as the guest’s exact operating system and service pack level, the installed version of the Guest Additions, users that are currently logged into the guest OS, network statistics and more.

Some of this runtime information is shown when you select Session Information Dialog from a virtual machine’s Machine menu. A more flexible way to use this channel is with the VBoxManage guestproperty command. For example, to have all the available guest properties for a given running VM listed with their respective values, use this command:.

To query the value of a single property, use the get subcommand as follows:. To add or change guest properties from the guest, use the tool VBoxControl.

This tool is included in the Guest Additions. When started from a Linux guest, this tool requires root privileges for security reasons. The Guest Control File Manager is a feature of the Guest Additions that enables easy copying and moving of files between a guest and the host system.

Other file management operations provide support to create new folders and to rename or delete files. The Guest Control File Manager works by mounting the host file system. Guest users must authenticate and create a guest session before they can transfer files. At the bottom of the Guest Control File Manager, enter authentication credentials for a user on the guest system. Transfer files between the guest and the host system by using the move and copy file transfer icons.

You can copy and move files from a guest to the host system or from the host system to the guest. Click Close to end the guest session. The Guest Additions enable starting of applications inside a guest VM from the host system. This feature can be used to automate deployment of software within the guest.

For this to work, the application needs to be installed on the guest. No additional software needs to be installed on the host. Additionally, text mode output to stdout and stderr can be shown on the host for further processing. There are options to specify user credentials and a timeout value, in milliseconds, to limit the time the application is able to run.

The Guest Additions for Windows allow for automatic updating. This applies for already installed Guest Additions versions.

Also, copying files from host to the guest as well as remotely creating guest directories is available. In server environments with many VMs, the Guest Additions can be used to share physical host memory between several VMs. This reduces the total amount of memory in use by the VMs. If memory usage is the limiting factor and CPU resources are still available, this can help with running more VMs on each host.

The Guest Additions can change the amount of host memory that a VM uses, while the machine is running. Because of how this is implemented, this feature is called memory ballooning. Oracle VM VirtualBox supports memory ballooning only on bit hosts. It is not supported on Mac OS X hosts. Memory ballooning does not work with large pages enabled. Normally, to change the amount of memory allocated to a virtual machine, you have to shut down the virtual machine entirely and modify its settings.

With memory ballooning, memory that was allocated for a virtual machine can be given to another virtual machine without having to shut the machine down. When memory ballooning is requested, the Oracle VM VirtualBox Guest Additions, which run inside the guest, allocate physical memory from the guest operating system on the kernel level and lock this memory down in the guest. This ensures that the guest will not use that memory any longer. No guest applications can allocate it, and the guest kernel will not use it either.

Oracle VM VirtualBox can then reuse this memory and give it to another virtual machine. The memory made available through the ballooning mechanism is only available for reuse by Oracle VM VirtualBox. It is not returned as free memory to the host.

Requesting balloon memory from a running guest will therefore not increase the amount of free, unallocated memory on the host. Effectively, memory ballooning is therefore a memory overcommitment mechanism for multiple virtual machines while they are running. This can be useful to temporarily start another machine, or in more complicated environments, for sophisticated memory management of many virtual machines that may be running in parallel depending on how memory is used by the guests.

At this time, memory ballooning is only supported through VBoxManage. Use the following command to increase or decrease the size of the memory balloon within a running virtual machine that has Guest Additions installed:.

You can also set a default balloon that will automatically be requested from the VM every time after it has started up with the following command:. By default, no balloon memory is allocated. This is a VM setting, like other modifyvm settings, and therefore can only be set while the machine is shut down. It avoids memory duplication between several similar running VMs. In a server environment running several similar VMs on the same host, lots of memory pages are identical.

For example, if the VMs are using identical operating systems. Page Fusion currently works only with Windows and later guests. The more similar the VMs on a given host are, the more efficiently Page Fusion can reduce the amount of host memory that is in use.

It therefore works best if all VMs on a host run identical operating systems. Instead of having a complete copy of each operating system in each VM, Page Fusion identifies the identical memory pages in use by these operating systems and eliminates the duplicates, sharing host memory between several machines.

This is called deduplication. If a VM tries to modify a page that has been shared with other VMs, a new page is allocated again for that VM with a copy of the shared page. This is called copy on write. All this is fully transparent to the virtual machine. You may be familiar with this kind of memory overcommitment from other hypervisor products, which call this feature page sharing or same page merging.

However, Page Fusion differs significantly from those other solutions, whose approaches have several drawbacks:. Traditional hypervisors scan all guest memory and compute checksums, also called hashes, for every single memory page.

Then, they look for pages with identical hashes and compare the entire content of those pages. If two pages produce the same hash, it is very likely that the pages are identical in content. This process can take rather long, especially if the system is not idling. As a result, the additional memory only becomes available after a significant amount of time, such as hours or sometimes days.

It can therefore achieve most of the possible savings of page sharing almost immediately and with almost no overhead. Page Fusion is also much less likely to be confused by identical memory that it will eliminate, just to learn seconds later that the memory will now change and having to perform a highly expensive and often service-disrupting reallocation. To enable Page Fusion for a VM, use the following command:. You can observe Page Fusion operation using some metrics. Enabling Page Fusion might indirectly increase the chances for malicious guests to successfully attack other VMs running on the same host.

See Section The Guest Additions provide services for controlling the guest system’s monitor topology. The resolution of a virtual monitor can be modified from the host side either by resizing the window that hosts the virtual monitor, through the view menu or through VBoxManage controlvm “vmname” setscreenlayout.

The decision is made automatically at each desktop session start. Since the mentioned monitor topology control services are initialized during the desktop session start, it is impossible to control the monitor resolution of display managers such as gdm, lightdm.

Please refer to Section 4. When this guest property is set then VBoxDRMClient is started during the guest OS boot and stays active all the time, for both ithe display manager login screen and the desktop session. Specifically, disabling a guest monitor except the last one invalidates the monitor topology due to limitations in the Linux kernel module vmwgfx. Chapter 4. Guest Additions. Table of Contents 4.

To allow for completely unattended guest installations, you can specify a command line parameter to the install launcher:. This automatically installs the right files and drivers for the corresponding platform, either bit or bit.

By default on an unattended installation on a Vista or Windows 7 guest, there will be the XPDM graphics driver installed. Instead, the WDDM graphics driver needs to be installed. This is only required for Vista and Windows 7. For more options regarding unattended guest installations, consult the command line help by using the command:. If you would like to install the files and drivers manually, you can extract the files from the Windows Guest Additions setup as follows:. To explicitly extract the Windows Guest Additions for another platform than the current running one, such as bit files on a bit system, you must use the appropriate platform installer.

Use VBoxWindowsAdditions-x The Guest Additions work in those distributions. You may choose to keep the distribution’s version of the Guest Additions but these are often not up to date and limited in functionality, so we recommend replacing them with the Guest Additions that come with Oracle VM VirtualBox.

The Oracle VM VirtualBox Linux Guest Additions installer tries to detect an existing installation and replace them but depending on how the distribution integrates the Guest Additions, this may require some manual interaction. It is highly recommended to take a snapshot of the virtual machine before replacing preinstalled Guest Additions.

See Section 4. They also come with an installation program that guides you through the setup process. However, due to the significant differences between Linux distributions, installation may be slightly more complex when compared to Windows. Before installing the Guest Additions, you prepare your guest system for building external kernel modules. This works as described in Section 2. If you suspect that something has gone wrong, check that your guest is set up correctly and run the following command as root:.

VirtualBox is free virtualization software that allows us home users to play with multiple operating systems within our main computer. By creating a virtual machine, we can run guest software, i. You could run Linux within Windows or the other way round.

We can also use different versions of Linux within Linux or Windows within Windows. Virtualization is massive right now. It allows individuals and enterprises to run several functions on a single computer, rather than forcing someone to find the space and the money to have more than one.

So rather than building a separate computer to run a different operating system, you only need one. At an enterprise level, rather than running a backup server, a separate mail server, and a separate SharePoint server, each can run in its own virtual instance on a single physical host machine.

Two terms you need to learn right away to be able to work with VirtualBox are host and guest. Guest refers to the operating system you will be running within the box.

For instance, if you want to run Linux within Windows, then Windows would be the host and Linux would be the guest. VirtualBox is free and fairly simple to use. However, there are a few configuration tricks you will need to know in order to get the best out of it. One of these is configuring VirtualBox to run a bit guest operating system. Loading a bit OS is simple, but running x64 takes a little more work.

VirtualBox should now set up your guest as directed. It could take a few seconds or a few minutes depending on your computer and required settings. All other defaults should be acceptable, but feel free to explore and configure as you see fit. Luckily, VirtualBox has a very comprehensive user manual. A new window will appear asking you to select a start disk. Your operating system of choice will perform the usual installation process and will eventually load into its desktop.

Depending on your computer, this could take longer than it usually would as your computer is not only running the host and VirtualBox itself, it is also running a virtualized installer.

Once loaded into your new bit guest, you can install apps, programs, and whatever you want to make it work how you want. When you have it running perfectly, navigate to the Machine menu at the top of the virtualization screen and click Take Snapshot. This takes an image of your guest so you can quickly restore a working version should you need to. VirtualBox is a great way to explore new operating systems without committing to one or reconfiguring a perfectly good computer.

I think it is an excellent piece of software and use it regularly to see how destructible Windows 10 is.

Org display server will be set up to use the graphics and mouse drivers which come with the Guest Additions. After installing the Guest Additions into a fresh installation of a supported Linux distribution or Oracle Solaris system, many unsupported systems will work correctly too, the guest’s graphics mode will change to fit the size of the Oracle VM VirtualBox window on the host when it is resized.

You can also ask the guest system to switch to a particular resolution by sending a video mode hint using the VBoxManage tool. Multiple guest monitors are supported in guests using the X. Org server version 1. The layout of the guest screens can be adjusted as needed using the tools which come with the guest operating system.

If you want to understand more about the details of how the X. Org drivers are set up, in particular if you wish to use them in a setting which our installer does not handle correctly, see Guest Graphics and Mouse Driver Setup in Depth. This will replace the drivers with updated versions. You should reboot after updating the Guest Additions. If you have a version of the Guest Additions installed on your virtual machine and wish to remove it without installing new ones, you can do so by inserting the Guest Additions CD image into the virtual CD-ROM drive as described above.

Then run the installer for the current Guest Additions with the uninstall parameter from the path that the CD image is mounted on in the guest, as follows:. While this will normally work without issues, you may need to do some manual cleanup of the guest in some cases, especially of the XFree86Config or xorg. In particular, if the Additions version installed or the guest operating system were very old, or if you made your own changes to the Guest Additions setup after you installed them.

They come with an installation program that guides you through the setup process. Mount the VBoxGuestAdditions. If the CD-ROM drive on the guest does not get mounted, as seen with some versions of Oracle Solaris 10, run the following command as root:.

Choose 1 and confirm installation of the Guest Additions package. After the installation is complete, log out and log in to X server on your guest, to activate the X11 Guest Additions. The Oracle Solaris Guest Additions can be safely removed by removing the package from the guest. Open a root terminal session and run the following command:. VirtualBox is free and fairly simple to use. However, there are a few configuration tricks you will need to know in order to get the best out of it.

One of these is configuring VirtualBox to run a bit guest operating system. Loading a bit OS is simple, but running x64 takes a little more work. VirtualBox should now set up your guest as directed. It could take a few seconds or a few minutes depending on your computer and required settings.

Home » Apple. Like this post? Please share to your friends:. Microsoft Windows is a group of many GUI based operating systems developed and offered. It allows individuals and enterprises to run several functions on a single computer, rather than forcing someone to find the space and the money to have more than one. So rather than building a separate computer to run a different operating system, you only need one.

At an enterprise level, rather than running a backup server, a separate mail server, and a separate SharePoint server, each can run in its own virtual instance on a single physical host machine. Two terms you need to learn right away to be able to work with VirtualBox are host and guest.

Guest refers to the operating system you will be running within the box. In addition, enabling 3D acceleration gives the guest direct access to a large body of additional program code in the Oracle VM VirtualBox host process which it might conceivably be able to use to crash the virtual machine.

The Aero theme is not enabled by default on Windows. See your Windows platform documentation for details of how to enable the Aero theme. This driver acts as a hardware 3D driver and reports to the guest operating system that the virtual hardware is capable of 3D hardware acceleration. When an application in the guest then requests hardware acceleration through the OpenGL or Direct3D programming interfaces, these are sent to the host through a special communication tunnel implemented by Oracle VM VirtualBox.

The host then performs the requested 3D operation using the host’s programming interfaces. With this feature, if an application such as a video player inside your Windows VM uses 2D video overlays to play a movie clip, then Oracle VM VirtualBox will attempt to use your host’s video acceleration hardware instead of performing overlay stretching and color conversion in software, which would be slow.

This currently works for Windows, Linux and Mac OS X host platforms, provided that your host operating system can make use of 2D video acceleration in the first place. Because 2D support is still experimental at this time, it is disabled by default and must be manually enabled in the VM settings.

The driver sends all overlay commands to the host through a special communication tunnel implemented by Oracle VM VirtualBox. On the host side, OpenGL is then used to implement color space transformation and scaling. With the seamless windows feature of Oracle VM VirtualBox, you can have the windows that are displayed within a virtual machine appear side by side next to the windows of your host. This feature is supported for the following guest operating systems, provided that the Guest Additions are installed:.

After seamless windows are enabled, Oracle VM VirtualBox suppresses the display of the desktop background of your guest, allowing you to run the windows of your guest operating system seamlessly next to the windows of your host.

The Host key is normally the right control key. This will enlarge the size of the VM’s display to the size of your host screen and mask out the guest operating system’s background. This provides the following advantages:. For example, to monitor VM performance and statistics. Arbitrary string data can be exchanged between guest and host. This works in both directions. To accomplish this, Oracle VM VirtualBox establishes a private communication channel between the Oracle VM VirtualBox Guest Additions and the host, and software on both sides can use this channel to exchange string data for arbitrary purposes.

Guest properties are simply string keys to which a value is attached. They can be set, or written to, by either the host and the guest. They can also be read from both sides. In addition to establishing the general mechanism of reading and writing values, a set of predefined guest properties is automatically maintained by the Oracle VM VirtualBox Guest Additions to allow for retrieving interesting guest data such as the guest’s exact operating system and service pack level, the installed version of the Guest Additions, users that are currently logged into the guest OS, network statistics and more.

Some of this runtime information is shown when you select Session Information Dialog from a virtual machine’s Machine menu. A more flexible way to use this channel is with the VBoxManage guestproperty command.

For example, to have all the available guest properties for a given running VM listed with their respective values, use this command:. To query the value of a single property, use the get subcommand as follows:. To add or change guest properties from the guest, use the tool VBoxControl. This tool is included in the Guest Additions. When started from a Linux guest, this tool requires root privileges for security reasons.

The Guest Control File Manager is a feature of the Guest Additions that enables easy copying and moving of files between a guest and the host system. Other file management operations provide support to create new folders and to rename or delete files.

The Guest Control File Manager works by mounting the host file system. Guest users must authenticate and create a guest session before they can transfer files. At the bottom of the Guest Control File Manager, enter authentication credentials for a user on the guest system.

Transfer files between the guest and the host system by using the move and copy file transfer icons. You can copy and move files from a guest to the host system or from the host system to the guest. Click Close to end the guest session. The Guest Additions enable starting of applications inside a guest VM from the host system. This feature can be used to automate deployment of software within the guest. For this to work, the application needs to be installed on the guest. No additional software needs to be installed on the host.

Additionally, text mode output to stdout and stderr can be shown on the host for further processing. There are options to specify user credentials and a timeout value, in milliseconds, to limit the time the application is able to run.

The Guest Additions for Windows allow for automatic updating. This applies for already installed Guest Additions versions. Also, copying files from host to the guest as well as remotely creating guest directories is available. In server environments with many VMs, the Guest Additions can be used to share physical host memory between several VMs. This reduces the total amount of memory in use by the VMs. If memory usage is the limiting factor and CPU resources are still available, this can help with running more VMs on each host.

The Guest Additions can change the amount of host memory that a VM uses, while the machine is running. Because of how this is implemented, this feature is called memory ballooning. Oracle VM VirtualBox supports memory ballooning only on bit hosts.

It is not supported on Mac OS X hosts. Memory ballooning does not work with large pages enabled. Normally, to change the amount of memory allocated to a virtual machine, you have to shut down the virtual machine entirely and modify its settings. With memory ballooning, memory that was allocated for a virtual machine can be given to another virtual machine without having to shut the machine down.

When memory ballooning is requested, the Oracle VM VirtualBox Guest Additions, which run inside the guest, allocate physical memory from the guest operating system on the kernel level and lock this memory down in the guest. This ensures that the guest will not use that memory any longer. No guest applications can allocate it, and the guest kernel will not use it either. Oracle VM VirtualBox can then reuse this memory and give it to another virtual machine.

The memory made available through the ballooning mechanism is only available for reuse by Oracle VM VirtualBox. It is not returned as free memory to the host. Requesting balloon memory from a running guest will therefore not increase the amount of free, unallocated memory on the host. Effectively, memory ballooning is therefore a memory overcommitment mechanism for multiple virtual machines while they are running. This can be useful to temporarily start another machine, or in more complicated environments, for sophisticated memory management of many virtual machines that may be running in parallel depending on how memory is used by the guests.

At this time, memory ballooning is only supported through VBoxManage. Use the following command to increase or decrease the size of the memory balloon within a running virtual machine that has Guest Additions installed:.

You can also set a default balloon that will automatically be requested from the VM every time after it has started up with the following command:. By default, no balloon memory is allocated. This is a VM setting, like other modifyvm settings, and therefore can only be set while the machine is shut down.

It avoids memory duplication between several similar running VMs. In a server environment running several similar VMs on the same host, lots of memory pages are identical. For example, if the VMs are using identical operating systems.
