<![CDATA[VM autostart stopped working]]>I have no idea what happened. I simply restarted my home server after some time and two out of the four VMs simply didn't start despite being configured to do so in XO-CE.
I googled up some thread where someone suggested flipping the autostart setting off and on via the console, which I did, but the VMS still refuse to autostart. They do start manually just fine.

I have also set every VM's autostart to disabled and then disabled the pool-wide autostart setting, rebooted the server, re-enabled everything, rebooted, and it's still not working 😞
Can anyone tell me what to do here, what to check? I don't really understand this system or Linux in general, everything I do is by copying what I find on internet or by trial and error.
I literally changed nothing about the server and it's just not working all of a sudden 😞

I checked and it's a real, documented XCP-ng parameter, "the delay to wait before a call to start up the VM returns", so that explains the behavior.
I couldn't find auto_poweron_delay documented anywhere in the XCP-ng or XO docs, so I'm not sure if it's something XO's advanced VM settings expose under a different name, or something unrelated you picked up while googling. 🤷
If you check the VM's Advanced tab in XO and see what's actually set there, that would help pin down which setting you're really dealing with.
Either way this looks like a gap in the autostart guide, since it doesn't mention that start-delay can interact with autostart at all.

I don't get it.
No idea how to achieve a startup delay for a specific VM though. There's also "auto_poweron_delay" and I don't understand what the difference from "start-delay" is.
