I have trouble getting a passthrough nic to be recognized in a guest VM (both BSD and Linux).
Running TrueNas release 12. I have 3 nics, 1 onboard and a dual nic card. All Intels.
So I have em0 (onboard), em1 (dual nic 1), em2 (dual nic 2). I am trying to passthrough em2.
What I did:
1. Followed the steps here to ensure I have virtualization enabled:
https://wiki.freebsd.org/bhyve/pci_passthru
2. Added relevant loader configs after determining the PCI device id:
3. Verified that the device is available as a passthrough (em2 became ppt0):
4. Created a VM (Tried pfSense and a generic Linux Distro) and assigned the passthrough device (of course, not at the same time):
5. Booted the VM
I can't see a nic.
One thing I suspect is that I see an error in the pciconf -lc output for the passthrough device:
But I don't know how to debug that one out.
Thanks for your help!
