(no title)

Yeap, actually I haven't run directly `bhyve` but using the `vm` wrapper as is very convenient.

I haven't looked at passrhrough yet, but I do feel that if I need to use it I would probably have to fight a bit with it, anyone had a hard experience setting it up?

No big fight, you just have to exclude the devices at boot so the vm can take them over [1] and if you have a AMD-System add that [2] and use the nvme virtual harddisk [3]

Nothing useful to add, just a "no". I wasn't trying to do GPU passthrough but instead passthrough a PCI card with four independent USB controllers so I could allocate those ports to VMs.

Excluded the devices at boot with pptdevs. Using vm for bhyve management so added `passthru0="10/0/0"` (device id) to the vm config. Started it up. Device was in the VM.
