Hello, I am having trouble getting an Nvidia K80 passed through to a vm.
when I launch the VM the host locks up and I need to reset the machine. I have another GPU (780Ti) in the system and when I pass that through everything works okay.
if I pass one or both of the GPUs on the K80 it just locks everything up (remotely) if I go to the physical machine I can still appear to do things in the shell however if I for example sudo reboot the machine will hang instead of rebooting so I am not sure if I can actually do anything to the machine after the VM kills the host.
Here is the VM config - I have tried this with and without the pci-hole64-size argument. I got it from a thread here where someone was trying to pass multiple video cards to one machine. it did not change anything for me

The host machine is an Asus TUF gaming B550 plus, AMD Ryzen 5 5600X, 64GB of ddr4 3000, and a few 250GB ssds and an older 1200w psu.
Proxmox 8.4.1, I have the "no subscription" repository enabled and the host machines software is up to date. the guest VM is ubuntu server 24.04.2
I see there are some people who have passed through a few K80s successfully, but this is an old GPU and I wonder if the software I am running is too new for this to work right.
