Dear Colleagues,

vm-bhyve keeps virtual machines on zfs volumes with volmode=dev. How can
I access/mount the filesystems within the volume when the virtual host
is offline? 

If I kept virtual disks in raw files, I could access them as devices
with mdconfig. But:

root at newserv:~ # mdconfig -a -f /dev/zvol/zroot/vm/mail/disk0 
mdconfig: /dev/zvol/zroot/vm/mail/disk0 is not a regular file
root at newserv:~ # 

Also, how can I exchange those zfs volumes for use with other
hypervisors? They are not real raw disk files so I cannot use
sysutils/vmdktool etc.
