Hi,

I have a problem about PCI passthrough on KGPE-D16. I plugged in a PCI to
USB adapter to the PCI slot, and it's in IOMMU group 7 with the ASpeed
video card and the LSI 1394a controller. I try to pass them all to a VM,
but then kernel crashes. I tried in Linux 4.9.47 and Linux 4.12.10.

Does anyone with KGPE-D16 have this problem?

Iru

You are attempting to pass the primary video device to a VM which hardly
ever works, I tried the same thing and it didn't work (I wanted my PCI
sound card in the VM, and as PCI doesn't support ACS and all the PCI
devices on the D16 are behind the same bridge they are in the same IOMMU
group so I had to do that - I ended up buying a USB sound adapter)

Now I'm using GTX 650 as my primary video device and not using the on board
ASpeed  video card.

Also I tried to pass the onboard USB controller to the VM, and also crashed
the kernel.

Damn :[
FYI you forgot to reply all - please re post this to the list :]

Hmm can I have dmesg logs and your libvirt or w/e VM config files? for the new config you are trying.
I am playing games right now with my pass thru usb ports.
