It is normal on my Quadro M5000 - these cards are not supported as primary display with passthrough. This might be something to do with ROM, but I was not successful trying to investigate further. To compensate for this all my virtual machines have serial console, so I can do "virsh console" B. -- Bronek Kozicki b...@spamcop.net _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
