VirtualBox is a free and open source virtualization 'hypervisor' for x86-based machines. VirtualBox can be installed and run on GNU/Linux and other Operating Systems.

The virtual machines provided by VirtualBox can be used to run a number of guest Operating Systems such as GNU/Linux, Windows, and others.

VirtualBox is available for Funtoo Linux on the arch profiles x86-32bit, x86-64bit and pure-64.

Glossary of Terms

Term	Explanation
Host OS	The Operating System on physical hardware that VirtualBox will be installed to and run from. i.e. Funtoo Linux
Guest OS	The Operating System that is run within a Virtual Machine provided by VirtualBox. Could be Funtoo Linux, another GNU/Linux distribution, Windows, etc.
Guest Additions	Guest Additions is a collection of applications, libraries and kernel modules/drivers that are installed in your Guest OS. These provide support for graphics, networking, file transfer, access to real physical devices (e.g. USB flash drive), and so on.

Host Installation

Warning

This page is currently being redeveloped.

Note

The following information is aimed primarily at VirtualBox on a typical "desktop" install of Funtoo Linux.

Binary VirtualBox

VirtualBox is also available as a binary package. If you wish to use the binary version see:

No results

The binary package contains extensions which are not available with the source package.

Installation

root # echo "app-emulation/virtualbox-extpack-oracle PUEL" >> /etc/portage/package.license/virtualbox
root # emerge app-emulation/virtualbox

Installation of app-emulation/virtualbox implies app-emulation/virtualbox-extpack-oracle.

Guest Additions

Make sure that user running X session belongs to vboxguest group. Create group when it does not exist. Add user to the group. That will enable :

Shared clipboard;
Display resizing;
Seamless mode;
Drag & Drop.

root # groupadd vboxguest
root # gpasswd -a ''user'' vboxguest

Windows Guests

Warning

This is new information.

VirtualBox versions less than 5.0

You must enable additions USE flag when you intend to install Windows as a guest O/S. That will also install the ISO image containing all necessary Windows guest drivers.

VirtualBox versions 5.0 and above

As of version 5.0 the USE flag additions has been removed from the package app-emulation/virtualbox. The guest additions ISO required for a Windows guest is now provided in a separate package, app-emulation/virtualbox-additions. Install this to access the guest additions ISO: /usr/share/virtualbox/VBoxGuestAdditions.iso.

Linux Guests

If you want to run Funtoo GNU/Linux as a guest O/S, emerge app-emulation/virtualbox-guest-additions in the Funtoo GNU/Linux guest O/S. For other GNU/Linux, please refer to VirtualBox documentation.

Post Installation

You will not be able to run and use VirtualBox as a regular user if you are not a member of the vboxusers group.

root # gpasswd -a ''user'' vboxusers

You must re-log so changes take effect.

Loading Modules

Required and optional modules must be loaded before launching VirtualBox. You can do that as root or upon boot.

Note

vboxnetadp and vboxnetflt are optional.

As root

root # modprobe vboxdrv
root # modprobe vboxnetadp
root # modprobe vboxnetflt

Upon boot OpenRC

Edit /etc/conf.d/modules :

modules="vboxdrv vboxnetadp vboxnetflt"

Kernel Driver

Each time a new kernel is installed, vboxdrv kernel module must be recompiled. To ensure Portage knows about that, look at /var/lib/module-rebuild/moduledb. The following record must be present.

a:1:app-emulation/virtualbox-modules-''version''

Running emerge @module-rebuild will recompile VirtualBox driver after installation of new kernel.

EFI case

latest releases of virtualbox have a volatile NVRAM and this makes an EFI guest boot troublesome. To workaround this following steps required:

remove any CD images (like systemrescuecd) from the VM settings
start the VM
wait for the countdown or press Esc immediately to reach the EFI shell
type edit startup.nsh to open the full-screen editor
enter "fs0:\EFI\Funtoo Linux [GRUB]\grubx64.efi" (including the double quotes, since the path contains spaces)
press CTRL-s (maybe twice) to save and confirm saving by pressing Enter
quit editor by pressing CTRL-q
type reset to reboot the machine (or kill the VM and boot it using the GUI)
wait for the countdown or press Enter to immediately run the startup.nsh script

EFI guests now should properly boot. reference reports: https://www.virtualbox.org/ticket/14279 and https://bugs.funtoo.org/browse/FL-2640
