Hello friends,
I use PVE 4.4 and want to passthrough ATI 6450 (UEFI Compatble) to virtual machine Windows 10 x64
When I simply add
in vmid.conf file, I get error:
01:00.0 - videoadapter
01:00.1 - is a sound device of videoadapter
if I change this string to correct value:
and run manually from command line:
vga passthrough work perfectly.
In case x-vga=on, but no pcie
problem remains the same:
PVE make wrong strings:
and generate error, wnen i start vm.
if i change to correct values:
and run vm from console, all works perfectly.
I get this problem with q35 chipset and i440fx chipset with both ovmf and seabios.
Does anyone knows how to solve this problem?

When I simply add
Code:
hostpci0: 01:00, x-vga=on, pcie=1
and I can see, that PVE make wrong passthrough string:kvm: -device vfio-pci,host=01:00.1,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,x-vga=on,multifunction=on: vfio: Device does not support requested feature x-vga
