Hi there,
I have a problem with vga passthrough of my amd rx580 gpu. It is about getting Error starting domain: Internal error: Unknown PCI header type ‘127’ when starting linux virtual machine in a virt-manager.
I believe it is a software problem of incorrect deinitialization in linux vm, because windows vm makes no problem for secondary passthrough.
Here is a video demonstration: https://youtu.be/Zg3cJHJtNzg
Any suggestions?
I do not know where exactly to report this issue, so created this post here hoping to get help.
Also I have created a post in reddit, no solution found there though.
