trying to start a vm with a pcie passthrough device, specifically an nvidia vGPU device, and starting the vm in the gui times out. when i try to
Code:
qm start vmid --timeout 300
i get
Code:
kvm: -device vfio-pci,sysfsdev=sys/bus/pci/devices/0000:16:01.3: vfio sys/bus/pci/devices/0000:16:01.3: no such host device: No such file or directory
start failed: QEMU exited with code 1
this seems like a pve issue. troubleshooting steps i tried:
shut down already running vGPU vm and start it again with qm start, get the same error. start previously running vGPU vm with gui, start works.
there are already 8 2b vm's running on this rtx a5000, the nvidia docs say you can run 12. the host itself has about 100GB ram left to start this vm, but somehow still has a problem allocating the 16GB memory for this vm. i'm honestly by now not sure if this is an nvidia driver issue or pve issue.
