Also, "vm destroy" does not destroy VMs, if they have snapshots:

# vm destroy my-test1
Are you sure you want to completely remove this virtual machine (y/n)? y
/usr/local/sbin/vm: ERROR: failed to destroy ZFS dataset d02/vm/my-test1
# zfs destroy d02/vm/my-test1
cannot destroy 'd02/vm/my-test1': filesystem has children
use '-r' to destroy the following datasets:
d02/vm/my-test1@2016-07-30-23:37:34
# 

I think "vm destroy" should always destroy the VM no matter the snapshots
and dependent clones.
