How to keep the VM boot state is not shut down？

 

[AKA]

I'm sorry, but probably no one here understands whatever you wanted to know.
Maybe try a more detailed rephrasing?

How can I keep the VM on and not be shut down by customers

First I would try to prevent that in the guests OS. Like removing the interface buttons for a shutdown.

And wouldn't be that hard to write a bash script that runs on the server using cron and checks if a VM is shutdown and if it finds one that should be running it could start it.

You just would need to have a list of VMIDs that should always be running, step through that list all 5 minutes or so and then use qm status <VMID> to check if the VM is running, if it is not it could be started with qm start <VMID>.

Edit:
Something like:

#!/bin/bash

VMIDLIST=(100 101 102 103) # list of VMIDs that should always be running

for vmid in ${VMIDLIST[*]}
do
    if [ $(qm status $vmid) == "status: stopped" ]; then
        qm start $vmid
    fi
done

How would I remove the shutdown button in the guest??

If you don't tell us what OS the guest is using thats hard to tell.

Sorry...its windows 11

For Win10 you can remove it using policies like for example described here. I guess for Win11 there should be something similar.
