## Using SSH:
## *  Log in to hypervisor, retrieve list of running VMs
## *  Log in to hypervisor, retrieve list of ZFS volumes
## *  List any VM matching spec ^vpp[\d]+-[\d+]$
## *  List any ZFS datasets matching matching spec ^ssd-vol0/vpp[\d]+-[\d+]$
## *  If --force is set:
##     *  Destroy matching VMs
##     *  Recursively delete any matching ZFS datasets
