Auto-Start Container if specific VM is up

[alexgoaga]

Hey guys,
Im running promox on an hp microserver gen 8 for a while now and works like a charm. Unfortunately on my specific setup i have multiple vms that mount some synologys on the network and some of them are going down / up quite often due to experiments. Some containers also mount some file from there

Is there any solution if i start a VM manual , others can auto join ?
Or better , if a ping gets response / heartbeat , atuo-start after 4-5 mins ?

some solutions come to mind:

* you create a script that starts the first vm and then the others, and only start the vm with this script
* you make use of the 'hookscript' functionality of vm to start others in the 'post-start' hook
* you have a timer/cronjob that queries the vm status and starts the others if its up (don't forget to track the on/off state correctly)
