Hi there,
problems...problems...problems... :-(
I bought a new USB PCIe Card today and passed it through a Windows 10. Inside the VM the PCIe Card is recognized as USB PCi device,
but if I shutdown the Windows VM the whole proxmox server freezes and doesn't even respond on the reset button.
These are my IOMMU Groups:
You see that the PCIe USB controller is in group 8 with the PCI bridge. So that shouldn't be the problem.
In the VM I pass device 03:00.0 through and that's it. Did I forget something? Why does the server freeze after Windows VM shutdown?
Do you have any ideas?
EDIT: Because I have the xhci_hcf driver in use and bound to two other devices, I have to eleminate the driver from the USB controller in group 8.
Maybe this is the clue, although I have read, that this is a tricky thing and doesn't always work. I am open for ideas. ;-)
Thanks a lot!
