After the setup of my first Proxmox VE, I need to shutdown and startup your Proxmox hardware node. There are many reasons for this such as adding new hardware or to apply new kernel updates.
Before shutting down the Host machine, I have to shutdown the LXC container and all VMs.
When I start the Proxmox VE host node, the VM will not start up automatically. I will do it manually.
Here is the way to make the VMs auto-start with the HOST.
Datacenter > Virtual Machine > 109 (example.com) > Options > Start at boot
Double click the “Start at boot”, select the check box and OK.
