Good morning,
I have problems with Windows VMs, I install and everything works, but when I try to integrate an NVidia GPU it crashes every now and then and if I insert a PCie USB Card the VM freezes and Windows does not start, has anyone already had these problems?

If you tell me all the tests and tests to do I will put them here

Thanks in advance,
Francesco
 
Hi,

How have you got declared your gpu in your configuration?
- blacklisting nvidia-nouveau
- BIOS configuration for iommu group

- Last joke: if your gpu passthrough was working before an update, check in your proxmox web interface if your gpu haven't move of iommu_group :p
I ve already taked two times this joke on my configuration.

Because you have a problem with usb passthrough too, have you checked fìrmware upgrade for your motherboard ?

Best regards,

I double-checked using the official proxmox guide (https://pve.proxmox.com/wiki/Pci_pa...ows you to,experimental feature in Proxmox VE!) and everything works, the PCie USB card, now I unplugged it, started the server, turned off the server and reconnected it is turned to work, for the GPU it goes a bit randomly
