Hi, i have a proxmox installation with three vm on it. One is a windows machine that i passthrough an AMD RX580 GPU and i screen that vm on a monitor. Everything was working fine until today, after i upgraded the proxmox installation. Something on the driver broke on the windows VM and i have no screen... how can i correct this? was thinking on making a downgrade. Some help please :(

Is there any information i can post here to debug the problem?

I have the proxmox installation drive, can i replace the installed components with those in the installation media? Without changing configurations to set up?
 
Hi. Thanks for your answer. Im now on the same place as last time. willing to upgrade my proxmox installation but im scared of loosing pci passthrough as the vm that has the gpu is my main computer. is there a safe way to revert installation if something goes wrong? would like to avoid ghosting the harddrive
