hi
My issue is that I used an AMD graphics card passthrough for a Windows virtual machine, and I encountered an error when I restarted it again.
qm stop >> qm start have errors
I tried the following steps:
add or remove Passthrough class parameters.
grub
vifo
use scripts
It looks like
It is worth noting that
dmesg in file
What else can I try? Thank you all for your hard work.
