Yes it works, I just tried it using sysutils/vm-bhyve (just add
virt_console0="Yes" to the configuration file).
Based on the logs, these device settings are used by it:
bhyve devices:
-s 0,hostbridge \
-s 31,lpc \
-s 4:0,virtio-blk,/dev/zvol/zroot/vms/freebsd14-test/disk0 \
-s 5:0,virtio-net,tap0,mac=58:9c:fc:aa:aa:aa \
-s 6:0,virtio-console,0=/vms/freebsd14-test/vtcon.0
I could connect to /vms/freebsd14-test/vtcon.0 using socat:
socat - UNIX-CONNECT:/vms/freebsd14-test/vtcon.0
Inside the vm it's /dev/vtcon/0.
