--- Comment #1 from Alex Williamson alex.williamson@redhat.com --- Use a Q35 VM configuration with the assigned GPU downstream of an emulated PCIe root port as a workaround. The driver assumes this configuration, presumably it's the only one that exists on bare metal, and reads from the upstream device without checking that it is actually present.
