VMs not working

Hi,

My VM's have stopped running, keep getting Domain id=1 is tainted message in the logs. I was initially trying to pass through an unassigned sata disk directly for new virtual machine however my other existing unrelated vm has stopped working.

Any help would be much appreciated.
