In openQA we support various backends which are able to 'host' tests. 'svirt' - one of those backends - is so generic that it allows to conned to a virtualization host via SSH a perform shell commands directly.
As VirtualBox has decent command line interface (especially VBoxManage command) it shouldn't be that hard to support VirtualBox in openQA's os-autoinst via svirt backend.
Add VirtualBox bootloader to openQA
