bhyve passthru of a PCI-e USB card

[shvehlava]

Hello, daemons,

In an effort to reduce my dependancy on many machines, I've become a big fan of bhyve.

There was one last thing I wanted to get working - I have a scanner that only works with linux. I got a PCI card with two usb interfaces, stuck it into the machine, checked that it works, disabled it in loader.conf, checked with vm passthru that it's available (YES) and when I try to start the vm, I get:

fatal; pci passthrough not supported on this system (no VT-d or amdvi)

I read on the bhyve wiki that one must make sure his system supports the following:

* CPU supports Intel IOMMU (a.k.a. VT-d) feature
* PCI device (and driver) supports MSI/MSI-x interrupts

acpidump -t | grep DMAR returns nothing
pciconf -ls | grep MSI returns 'PCI-Express 2 endpoint MSI 1 max data 128(128)'

My question is, am I out of luck? I scoured BIOS settings for anything VT-d, but best I got is a single checkbox for 'virtualization' (which is checked of course). The host is not booting via UEFI, if that might make any difference.

Thanks!

Because of the exodus of most of our FreeBSD users to the official FreeBSD forums, you probably will get more feedback there: https://forums.freebsd.org/

Alright, I'll give it a shot. Thank you. But I'll be back.
