There was a thread here a while back about some adventurer trying to
passthrough an Nvidia GPU which ultimately did not work. Unfortunately
that still seems to be the case. I'm using 12.x and I could not get it to
work in FreeBSD, Linux, or Windows guest. Win10 wouldn't even boot with it
passed through. Linux wouldn't load the driver(could have been me) and
FreeBSD guest loaded the driver, but I could not do anything useful with
the card. For example, nvidia-smi -q reported No devices were found. Here
is the guest view:
vgapci0@pci0:0:1:0: class=0x030000 card=0x77101558 chip=0x1f5010de

cap 01[60] = powerspec 3 supports D0 D3 current D0

cap 10[78] = PCI-Express 2 legacy endpoint max data 128(256) FLR RO NS
link x16(x16) speed 2.5(8.0) ASPM disabled(L0s/L1)
I believe in earlier discussion there was objection to overcoming Nvidia's
virtualization restrictions, but I think since then both vmware and kvm
have implemented workarounds to allow for this.
Is anyone one currently working on this or needs some testing done?
