Description gdinolt 2020-01-24 23:50:37 UTC 
The VM command fails with error:

/usr/local/sbin/vm: ERROR: unable to load vmm.ko!

The error occurs because (at least in FreeBSD 13)

kldstat -qm vmm.ko

returns a value of 1, even if vmm.ko is already loaded.

The error is in /usr/local/lib/vm-bhyve/vm-util

         kldload ${_mod} >/dev/null 2>&1
         [ $? -eq 0 ] || util::err "unable to load ${_mod}.ko!"

I replaced the -qm with -qn, which seems to work at least as far as getting vm to start.
