::'''Scripting for Lab2'''. Lab 2 could be modified to have students create or be exposed to shell scripts with use the '''virtual shell''' ('''virsh''') to '''display in zenity available VMS in checkbox form to select and launch'''. Likewise, script can be launched to '''display in zenity VMs that are currently running in order to shutdown''' (perhaps in same fashion as a zenity dialog box).
