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

the VM OS actually can see the GTX Graphics card. The<br>
problems only begin after installing the NVIDIA drivers. So<br>
this is a troubleshooting attempt.<br>

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