I'm making progress on my VM.  If I start my unRAID, start libvirt, then start my VM I get passthru of the GPU and Ceton card.  I can run it and restart it.  But I have problems if I shut down.

 

If shut down and run virsh start or virsh create again, but VM starts (according to virsh list) but doesn't show up on the monitor.  Since I can't use VNC with GPU passthru, I have no way to interact with the VM and have to destroy it.

 

Are others having luck with shutdown and power up again?  If so, any suggestions?

 

Thanks

Some GPUs do not support this yet and a symptom of that can be lack of support for proper power management (e.g. shutdown).  Normally when a GPU is attached to an OS that is shutdown, it's expecting to lose power, which will also clear memory from the device making it ready for next boot.  This doesn't happen with a VM as the host still is on and providing power.

 

There's not much you can do to improve this situation other than trying a different GPU, but in a future release, we will have a new method to approaching GPU assignment that may have more success on a wider array of hardware.  Stay tuned.

What GPU are you using?
