Jul 27, 2009  Guest Additions installs on the guest system and includes device drivers and system applications that optimize performance of the machine. Launch the guest OS in VirtualBox and click on Devices and Install Guest Additions. The AutoPlay window opens on the guest OS and click on the Run VBox Windows Additions executable.

The following section describes known problems with this release of Oracle VM VirtualBox. Unless marked otherwise, these issues are planned to be fixed in later releases.

  • The following Guest SMP (multiprocessor) limitations exist:

    • Poor performance with 32-bit guests on AMD CPUs. This affects mainly Windows and Oracle Solaris guests, but possibly also some Linux kernel revisions. Partially solved for 32-bit Windows NT, 2000, XP, and 2003 guests. Requires the Guest Additions to be installed.

    • Poor performance with 32-bit guests on certain Intel CPU models that do not include virtual APIC hardware optimization support. This affects mainly Windows and Oracle Solaris guests, but possibly also some Linux kernel revisions. Partially solved for 32-bit Windows NT, 2000, XP, and 2003 guests. Requires the Guest Additions to be installed.

  • NX (no execute, data execution prevention) only works for guests running on 64-bit hosts and requires that hardware virtualization be enabled.

  • Guest control. On Windows guests, a process started using the guest control execute support will not be able to display a graphical user interface unless the user account under which it is running is currently logged in and has a desktop session.

    Also, to use accounts without or with an empty password, the guest's group policy must be changed. To do so, open the group policy editor on the command line by typing gpedit.msc, open the key Computer ConfigurationWindows SettingsSecurity SettingsLocal PoliciesSecurity Options and change the value of Accounts: Limit local account use of blank passwords to console logon only to Disabled.

  • Compacting virtual disk images is limited to VDI files. The VBoxManage modifymedium --compact command is currently only implemented for VDI files. At the moment the only way to optimize the size of a virtual disk images in other formats, such as VMDK or VHD, is to clone the image and then use the cloned image in the VM configuration.

  • OVF import/export:

    • OVF localization, with multiple languages in a single OVF file, is not yet supported.

    • Some OVF sections like StartupSection, DeploymentOptionSection, and InstallSection are ignored.

    • OVF environment documents, including their property sections and appliance configuration with ISO images, are not yet supported.

    • Remote files using HTTP or other mechanisms are not yet supported.

  • Neither scale mode nor seamless mode work correctly with guests using OpenGL 3D features, such as with Compiz-enabled window managers.

  • The RDP server in the Oracle VM VirtualBox extension pack supports only audio streams in format 22.05kHz stereo 16-bit. If the RDP client requests any other audio format there will be no audio.

  • Dev-c++ package for discord. Preserving the aspect ratio in scale mode works only on Windows hosts and on Mac OS X hosts.

  • On Mac OS X hosts, the following features are not yet implemented:

    • Numlock emulation

    • CPU frequency metric

    • Memory ballooning

  • Mac OS X guests:

    • Mac OS X guests can only run on a certain host hardware. For details about license and host hardware limitations. See Section 3.1.1, “Mac OS X Guests” and check the Apple software license conditions.

    • Oracle VM VirtualBox does not provide Guest Additions for Mac OS X at this time.

    • The graphics resolution currently defaults to 1024x768 as Mac OS X falls back to the built-in EFI display support. See Section 3.14.1, “Video Modes in EFI” for more information on how to change EFI video modes.

    • Mac OS X guests only work with one CPU assigned to the VM. Support for SMP will be provided in a future release.

    • Depending on your system and version of Mac OS X, you might experience guest hangs after some time. This can be fixed by turning off energy saving. Set the timeout to 'Never' in the system preferences.

    • By default, the Oracle VM VirtualBox EFI enables debug output of the Mac OS X kernel to help you diagnose boot problems. Note that there is a lot of output and not all errors are fatal. They would also show when using a physical Apple Macintosh computer. You can turn off these messages by using the following command:

      To revert to the previous behavior, use the following command:

    • It is currently not possible to start a Mac OS X guest in safe mode by specifying the -x option in VBoxInternal2/EfiBootArgs extradata.

  • Oracle Solaris hosts:

    • USB support on Oracle Solaris hosts requires Oracle Solaris 11 version snv_124 or later. Webcams and other isochronous devices are known to have poor performance.

    • Host Webcam passthrough is restricted to 640x480 frames at 20 frames per second due to limitations in the Oracle Solaris V4L2 API. This may be addressed in a future Oracle Solaris release.

    • No ACPI information, such as battery status or power source, is reported to the guest.

    • No support for using wireless adapters with bridged networking.

    • Crossbow-based bridged networking on Oracle Solaris 11 hosts does not work directly with aggregate links. However, you can use dladm to manually create a VNIC over the aggregate link and use that with a VM. This limitation does not exist in Oracle Solaris 11u1 build 17 and later.

  • Neither virtio nor Intel PRO/1000 drivers for Windows XP guests support segmentation offloading. Therefore Windows XP guests have slower transmission rates comparing to other guest types. Refer to MS Knowledge base article 842264 for additional information.

  • Guest Additions for OS/2. Seamless windows and automatic guest resizing will probably never be implemented due to inherent limitations of the OS/2 graphics system.

  • Some guest operating systems predating ATAPI CD-ROMs may exhibit long delays or entirely fail to boot in certain configurations. This is most likely to happen when an IDE/ATAPI CD-ROM exists alone on a primary or secondary IDE channel.

    Affected operating systems are MS OS/2 1.21: fails to boot with an error message referencing COUNTRY.SYS and MS OS/2 1.3: long boot delays. To avoid such problems, disable the emulated IDE/ATAPI CD-ROM. The guest OS cannot use this device, anyway.

In order to access certain aspects of a virtual machine in VirtualBox, you will need to install Guest Additions (similar to VMWare Tools I guess)

There is a manual page for installing Guest Additions but not all of it is self-explanatory…

First you need to log into your Linux virtual machine (VM) and install/configure x, y and z.

Install DKMS

This part is relatively straightforward, just install using whatever package manager your Linux distribution has. The below example uses APT that comes with Debian-based distros:

Where to find VBoxGuestAdditions.iso

Usefully Oracle don’t tell you in their guide, but it is available with the rest of the downloads at http://download.virtualbox.org/virtualbox/

So for example for version 4.1.6 the VBoxGuestAdditions_4.1.6.iso is located at http://download.virtualbox.org/virtualbox/4.1.6/VBoxGuestAdditions_4.1.6.iso

You need this image to install the VirtualBox Guest Additions themselves onto your VM, so you can either download it to your Linux VM and mount it there, or (which is what I did) download it to your Mac OS X host and mount it in the DVD drive using the VirtualBox Manager.

How to mount the image

Additions

You need to mount the image on the Linux VM, so that you can install VirtualBox Guest Additions from it. If you have mounted it in the VirtualBox Manager in the DVD drive then you will still need to mount it in the Linux VM; Since I can’t remember the last time I had to mount something in *nix from the command-line, here’s a quick way.

Then you should see VBoxLinuxAdditions in that directory, which you need to run as per the manual. If the above doesn’t work it might be because your DVD drive in VirtualBox is called something else, like dvd (instead of dvd1) which probably differs depending on which distro you’re using.

Then you need to run the installer.

Virtualbox Guest Additions Mac Os X Host

Once that’s done you can restart.

Everything should be finished now installation/configuration-wise, but you might encounter some problems… (otherwise skip to Mount the host folder)

Kernel header problems

I got some missing kernel header problems when trying to install Guest Additions, which if building the main Guest Additions module fails will be logged.

Review

If you see something like this…

So you can do just that!

Hopefully this should install now (although the XFree86 bit will fail, assuming you’re using the command-line) and you may need to restart the VM, although I’m not sure.

Mount the host folder

You can create the host folder in the VirtualBox Manager in the Shared Folders tab on the Settings for that VM. If you add it on the command-line it’ll appear under the machine folders anyways. If you want to type it though, here’s what you’d type into the Mac OS X terminal (note this is the only thing that you’d type into the host itself)

To mount the Shared Folder from within the guest, the instructions from Ubuntu (as my guest is Ubuntu, although I think this is a better way to mount it anyways) were very useful.

Just change the target to be wherever you want the Shared Folder to be mounted in the guest. Now in theory if you go to that path in the guest, it should be the same as the directory you shared from the host!
