I am currently
using a GTX 580 for passthrough. The 500 series does not
support UEFI as far as I'm aware. If I remember
correctly, that error occured when the card was already
claimed by something. My card is very finnicky about getting
claimed so I usually need to 'reboot' the card after
freeing it from the NVIDIA driver or a VM. I just do this by
suspending but I'm sure there's another way to power
cycle just the card. You definitely need to use one of the
older tutorials, any one that uses EFI won't work for
I would try launching the card with PCI stub and then
pulling the ROM, maybe vfio-pci is somehow claiming the
card. My current procedure is to launch both GTX 580's
with PCI stub initially and then bind one to vfio and the
other to NVIDIA for my host OS. Not sure how to help with
your specific problem but I can share more about my setup if
it would help. I'm using a Win 7 guest so that could be

It's pretty well guaranteed that a 500 series GeForce
does not support
UEFI. AFAIK, there's not a terribly high success rate
with these cards
either. The 600 series are generally what I consider the
bottom end of
working reasonably well. Otherwise there's not really
information in your report to provide any specific advice.
