VirtualBox
VirtualBox is an x86 virtualization software package developed by Oracle.
Determine which kernel you are using
Solus support both a current and lts kernel. It is important to install the version that corresponds to your kernel.
If you aren't sure which kernel you are running, run the following in terminal:
uname -r
You will either have a .current or .lts suffix. Examples: 4.13.12-32.current or 4.9.61-57.lts
Solus as Host
VirtualBox is available in the Software Center, select the package that matches your kernel.
| virtualbox | virtualbox-current |
|---|---|
| VirtualBox modules for the linux-lts kernel | VirtualBox modules for the linux-current kernel |
Troubleshooting
If the wrong VirtualBox package was installed, the following error will pop up when starting a virtual machine. Please check the instructions just above to install the correct package for your kernel.

Preparing your system
Before you start, ensure your all packages are up-to-date on the virtual machine
sudo eopkg upgrade
For using VirtualBox, it is important to install the correct headers for your kernel
If you have a lts kernel, install the lts headers
sudo eopkg install linux-lts-headers
If you have a current kernel, installing the current headers
sudo eopkg install linux-current-headers
Make sure you have the necessary packages installed
sudo eopkg install gcc make autoconf binutils xorg-server-devel
Reboot the virtual machine.
Install the Guest Additions
Now install the Guest Additions : from the VirtualBox menu Devices -> Insert Guest Additions CD image...
On the guest Machine, open Files and click on the optical drive icon (CD name starts with VBOXADDITIONS) then click on the Run Software button and follow the on screen instructions.

Note: For each kernel update you will need to rebuild the VirtualBox Modules. So simply remount the ISO and run the instructions again.
Virtual machine settings
Here is a brief overview on some options you may want to set (you can only do it when your virtual machine is not running).
Select your guest machine and click on the Settings icon.
Clipboard Sharing, Drag & Drop
By default, Clipboard Sharing and Drag'n'Drop are disabled, you can change this in General -> Advanced

Number of CPU
Virtual machines are created with only 1 CPU. You can change this in
System -> Processor
3D Acceleration
For better performances, it is strongly recommended to enable 3D Acceleration in Display -> Screen
USB Controller
If you have installed the extension pack and your hardware supports it, you set the USB Controller to USB 2.0 or 3.0, in USB
Note: Access to USB is granted by the user group vboxusers on the Host operating system. You can add yourself to this group with the following command
sudo usermod -aG vboxusers `whoami`
Shared Folders
You can share folders from the Host to the Guest in Shared Folders
Note: auto-mounted shared folders are mounted into the /media directory, along with the prefix sf_. For example, the shared folder myfiles would be mounted to /media/sf_myfiles. Access to auto-mounted shared folders is only granted to the user group vboxsf on the Guest operating system.
Execute these commands to set the permissions and add yourself to the group
sudo chmod 755 /media
sudo usermod -aG vboxsf `whoami`
