Yeah, adding testing would be good. From this list of limitations: - PCI passthrough require permissive mode - at most 26 emulated disks are supported (more are still available as PV disks) - only one nic is supported - graphics output (VNC/SDL/Spice) not supported PCI passthrough requiring permissive mode is fine for now. 26 emulated disks is probably fine forever. We should have support for multiple nics, and I have a idea for that. The lack of graphics output is probably the biggest limitation at this time. Regards, Jason
