Hi everyone,

I switched from Esxi to Proxmox, GPU passthrough is fine on Esxi but not working with Proxmox, I got this error when start the VM with GPU added:"unable to read tail (got 0 bytes)".

I also got some problems as cant reboot/shutdown host/guest

On guest I got this error: TASK ERROR: VM quit/powerdown failed - got timeout

On host, it is like infinity countdown :(
My system:
Ryzen 5 1600X
X370 Gaming K4
RX 580 + RX 470
16 GB DDR4
Can someone help me ? :(
