How to start a VM permanently.

[llorenzogo]

Hi there!

i have a VM that is used by a lot of users and sometimes someone accidentally shutdown the server. Does anybody knows how can I configure Proxmox to auto start the VM?

Kind regards!!
Leo.

GUI: VM - Options - Start at boot (Yes)

Hi, but what I need is not to start when the whole proxmox boot, I need it to start when the vm is down.

You can check whether the VM is running with the qm command and you can start the VM if it is not running: qm status 100 | grep -q 'stopped' && qm start 100. You could automate this to run every minute in a cron-job.
Or you can create a hookscript to start the VM when it is shut down. In both cases you might want to check if the Proxmox host is shutting down first.

What about enabling HA? If the VM is shutdown from inside, it should be started right away as only shutting it down via Proxmox VE tooling (from the outside) would change the desired HA state of the VM

Assuming it's a windows system, you can set the permissions/policies to prevent UNAUTHORIZED users from shutting down the system. I guess it can be done on linux as well.
