For the present I think I've found a workaround not directly related to
vm-bhyve.  I'm going to insert "service vm stop" into the doshutdown()
procedure in /usr/local/etc/apcupsd/apccontrol before the actual
${SHUTDOWN}. It should give the VMs sufficient time to shutdown before
the actual /sbin/shutdown is executed.

Do you think the above hack would have any negative effects?
