VM Shutting Down when started #6

Closed ghost closed 1 year ago

ghost commented 3 years ago

Hey guys, I've been trying to get single gpu passthrough working for several days to no avail. Finally asking for help since I have no idea what I'm doing wrong. This time I followed this (https://github.com/QaidVoid/Complete-Single-GPU-Passthrough) guide and have done all the steps. The problem is that when I start the vm it goes to a black screen and then to my motherboards loading screen, though nothing happens. I don't understand what the problem is in the logs: https://hastebin.com/ofazewelum.swift.

Specs: B450 Tomahawk, Ryzen 3600x, Nvidia 2080 Super, and running Ubuntu 21.04. SVM, NX, and IOMMU and enabled in bios.

Libvirt is exiting with following error:

libvirt:  error : libvirtd quit during handshake: Input/output error

Does the VM work without passthrough?

If not, I think libvirt is broken on your system.. In that case, you can try uninstalling it completely and installing it again or downgrading to the older version of libvirt..

The vm works fine without passthrough, tried a reinstall of libvirt but didn't help.

I also tried changing one of the hook scripts and I get this now, removing the devices from the vm (just to test) doesn't help

Please post your libvirt hook scripts and also the devices list from /dev/input/by-id.

Your script worked fine for me. Not sure what might be the cause of your issue.. I still think it might be the problem with libvirt.. If you can, downgrade libvirt and check..

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
