[vfio-users] Nvidia Error 43 and vendor_id state='on'

[Jayme Howard]

When I get error 43, I generally just delete the video card (and the
virtual one) from the device manager a few times, rebooting in between.
Eventually it comes back just fine.  It's definitely not ideal, but it's
worked for me so far.
