Hi,

Thanks for trying to help. I tried it both ways - in loader.conf and 
from the loader prompt but unfortunately it didn't work. For 
clarification, here's the exact way I start the VM:

1. $ screen -S fbsd11-vm
2. $ sudo su -
3. # (cd to where vm is)
4. sh /usr/share/examples/bhyve/vmrun.sh -c 4 -m 8192M -t tap3 -d 
fbsd-guest.img fbsd-guest

If I transfer the VM to a freebsd-11 host (r333874) it also happens. So 
the behaviour is a property of the VM. Unless of course the issue is 
with bhyve itself on both -stable and -current.

A possible clue (but I'm really out of my depth here) is ISTR something 
like this happening if say the VM is called say fbsd-guest and is then 
subsequently launched with some other name like fbsd11guest.

Any ideas?

thanks,
