I'm guessing that it has to do with the nvidia-specific quirks implemented where the PCI BAR's are used to access the PCI Config Space and other BAR's. See: https://github.com/qemu/qemu/blob/master/hw/vfio/pci-quirks.c I think before others worked around it somewhat by reserving the memory and having 1:1 mappings ( http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through ), but that isn't really a proper solution. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
