[vfio-users] KVM + QEMU + GPU passthrough (Windows7 Guest)

[José Ramón Muñoz Pekkarinen]

	Hi,

	Actually it's more funny, it really works like you said, but, for any 
reason vfio-pci.ids doesn't prevent radeon and my xorg server to take the p-t 
gpu, and do their business. So using pci-stub.ids I can avoid ioh3420.

	Then my question is, how vfio-pci.ids is different to pci-stub.ids, and why 
it works better with the latest?

	Thanks!

	José.
