Start VM after a specific LXC start

[Vittorio]

Hi all

Is it possible to start a VM after starting a specific LXC that has also a startup delay?

Actually I have set up the VM as start order 3 and a couple of container as start order 1 and 2 and a startup delay of 90 sec each

But the VM start as soon as the first container start.

Is there a way to do it?

Thanks

The VM then should only start after 180 seconds. Strange that this isn't the case for you.

You could script something using hook scripts.

Where can I find info regarding hook scripts?

What can I assume is that startup delays works only between VMs or LXCs, not between both.
So if I have more than one VM, it respects the orders and delay, same in LXCs.

Thanks

Isn't well documented. Search this forum for "hook script" and have a look at the example script: https://git.proxmox.com/?p=pve-docs.git;a=blob;f=examples/guest-example-hookscript.pl;hb=HEAD

So you could edit the exampel script to something like...

elsif ($phase eq 'post-start') {

     # Second phase 'post-start' will be executed after the guest
     # successfully started.

     print "$vmid started successfully.\n";
     # wait 120 seconds and start VM with VMID 200 after LXC with VMID 100 has finished starting    
     if ($vmid eq '100') {
         sleep 120
         qm start 200
     }

 }
