===== VM Auto Start (Start At Boot) =====

  - Select the VM
  - Click the menu **Options**

===== VM Auto Shutdown =====

  * First, we must install QEMU Guest Agent

  apt install qemu-guest-agent

  * Find the menu **QEMU Guest Agent**, make sure it's enabled
  * If enabled, when the host shuts down, Proxmox will send a proper shutdown command to the VM
