Hello to everyone.
I'm trying to passthru my GPU (RTX 2080 ti) from the host OS (FreeBSD 14.0 to my Windows 10 guest os) using vm-bhyve. This is how I have configured it :
this is my Windows10.conf file :
This is what happens when I try to start the vm :
it does not boot. But when I remove these args :
it boots regularly. So,there is something wrong with the passthru arguments. Take in consideration that I can pass thru the GPU if I don't use vm-bhyve,so the problem is with it. I mean,if I use the raw bhyve parameters,like these :
The vm boots regularly and I see the gpu on Windows 10 guest,even if it gives error 43,but that's another story).
