def self.register(cli)
  cli.desc "Restart virtual machines or containers (reboot)"
  cli.long_desc <<~HELP
    Reboot one or more virtual machines or containers. Sends a reboot
    signal to the guest OS for a clean restart.

    EXAMPLES
      Reboot a VM:
        $ pvectl restart vm 100

      Reboot a container:
        $ pvectl restart ct 200

      Reboot all VMs with a specific tag:
        $ pvectl restart vm --all -l tags=webserver --yes

    NOTES
      For VMs, this sends an ACPI reboot signal (requires guest agent or
      ACPI support). For containers, uses LXC reboot.

      For a hard reset (equivalent to pressing the reset button), use
      'pvectl reset' instead (VMs only).

      pvectl help shutdown        Graceful shutdown without restart
