virshall can start, shutdown or destroy all VMs on a hypervisor LAB so I can remove 'start' from create and pristine; sometimes it is useful to only create (but not start) the LABs. Similarly, sometimes bringing the LAB into pristine state, but without restarting the VMs, is useful.

## 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 any of these exist, bail and require the user to run ./destroy first
|
|
##
|
|
##
|
|
## * Log in to the hypervisor, and:
|
|
## * Clone the base image to all VM names (ssd-vol0/vpp0-[0-3])
|
|
## * Mount these in a staging directory
|
|
## * Rsync over our build/$(overlay)/$(hypervisor)/*
|
|
## * Unmount the staging directories
|
|
## * Start the VMs
