  • cat README
  • facter ipaddress
  • systemctl --all | grep pe- command to validate that all PE services are fully started, then use the quest tool to restart the quest.
  • restart_classroom_services.sh. If still observe stopped Puppet-related services (e.g. pe-console-services) several minutes after the VM has started, double check that you have sufficient memory allocated to the VM and available on your host, then use the following restart script to restart these services in the correct order.

Here's some examples of these commands in action.
