I've been using a Proxmox home server for quite some time now without many problems.
Recently i got an AMD Navi 10 RX 5700 XT and tried to pass it through to a windows VM.
I mainly followed the official Proxmox guide but got it running by using some other tutorials too.
For now, it works once after i reboot the host. Then its no problem to start the VM, but after a restart the VM doesnt start no more, showing this error:
swtpm_setup: Not overwriting existing state file. kvm: ../hw/pci/pci.c:1637: pci_irq_handler: Assertion 0 <= irq_num && irq_num < PCI_NUM_PINS' failed.
stopping swtpm instance (pid 98348) due to QEMU startup error
TASK ERROR: start failed: QEMU exited with code -1`
I tried fixing it using this but it didnt change much.
EDIT: link was not shown
dmesg also reported
vendor_reset: module verification failed: signature and/or required key missing - tainting kernelHowever, according to https://github.com/gnif/vendor-reset/issues/46#issuecomment-983087796 this error is not as important...To everyone else encountering this error, I finally fixed it this way: This forum entry sent me here, which then helped me resolve the issue. Huge thanks to you, InEnduringGrowStrong, for pushing me in the right direction.
Ah nice you got it working.
Once it works it's great.
I've been running mine for a while now, but purposefully avoided Kernel upgrades so far.
Haha, I already started worrying about that :) But you‘re right, its great.
