ASUS PN40 can not pass through the nuclear display #1

Open wnark opened 2 years ago

wnark commented 2 years ago

Hello, I am ASUS PN40 j4125, but after I pass through the core display, I get an error at startup:

virsh start ubuntu20.04
error: Failed to start domain ubuntu20.04
error: internal error: qemu unexpectedly closed the monitor: 2022-04-13T04:08:31.931342Z qemu-system-x86_64: -device vfio-pci,host=0000:00:02.0,id=hostdev0,bus=pcie.0,addr=0x2: vfio 0000:00:02.0: error getting device from group 1: Invalid argument
Verify all devices in group 1 are bound to vfio-<bus> or pci-stub and not already in use

I have gone to bios to open vt-d, and this pci group only has this nuclear display

My virtual machine's virsh parameters are： ubuntu.txt I've tried pve but can't pass through either. Passing through usb devices is normal.
