$ ./lab.sh start

Shutdown all domains

$ ./lab.sh stop

Get the domstate of all domains

$ ./lab.sh status

Return domain names as a shell list

$ ./lab.sh get-nodes

Execute a command on each node and print results on stdout/stderr

$ ./lab.sh exec ls -lah

Print the snapshots associated with each domain

$ ./lab.sh list-snapshots

Create a snapshot for each domain using the name specified

$ ./lab.sh create-snapshots initial_snapshot

Restore each domain using the specified snapshot name

$ ./lab.sh restore-snapshots initial_snapshot

Delete snapshot for each domain

$ ./lab.sh delete-snapshots initial_snapshot

Validate connectivity to nodes via SSH

$ ./lab.sh ping

Create bash completion rules

# ./lab.sh bash-completion > /etc/bash_completion.d/lab
