# VirtualBox
|
|
|
|
[VirtualBox](https://virtualbox.org) 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:
|
|
|
|
``` bash
|
|
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.

## Solus as Guest

|
### Preparing your system
|
|
Before you start, ensure your all packages are up-to-date on the virtual machine
|
|
|
|
``` bash
|
|
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
|
|
|
|
``` bash
|
|
sudo eopkg install linux-lts-headers
|
|
```
|
|
|
|
If you have a **current** kernel, installing the current headers
|
|
|
|
``` bash
|
|
sudo eopkg install linux-current-headers
|
|
```
|
|
|
|
Make sure you have the necessary packages installed
|
|
|
|
``` bash
|
|
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](https://www.virtualbox.org/manual/ch01.html#intro-installing) 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
|
|
|
|
``` bash
|
|
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
|
|
``` bash
|
|
sudo chmod 755 /media
|
|
sudo usermod -aG vboxsf `whoami`
|
|
```
