- Clover is then installed on the USB drive
- Clover Configurator is then run on the USB drive
- The USB drive contents are copied to the VM host
- VNC is used to connect to the guest UI
The qxl virtual video device is used (part of the standard kvm qemu install)

	be some cases where these are mixed up]
