virtio_console in bhyve? (FreeBSD host and guest)

Some more information:

When I deploy a Linux guest virtual machine on that FreeNAS system,
bhyve is invoked in exactly the same way:

bhyve [...] -s '30,virtio-console,org.freenas.vm-tools=/var/run/containerd/b5652839-4765-4384-8cd0-90964d4b1b4f.vmtools.sock'

(different UUID, of course).

Yet, in Linux the virtio_console is probed correctly, a device named
'/dev/virtio-ports/org.freenas.vm-tools' is created in the guest and the
guest and the host can communicate.

So the problems seems to lie not with FreeNAS but with the FreeBSD
implementation of virtio_console(4).

Anyone? Is this even the correct mailing list or should I address
freebsd-emulation or something entirely different like -stable?

Thanks,
Patrick
