    Hi everyone! I've upgraded standalone host from 8.2 to 8.3 yesterday. On 8.2 I was using /etc/rc.local and vApps to autostart VM-s, it was working like a charm, especially since you can delay startup time which is quite handy if you have block based storage that needs long time to boot so you can delay boot of file server VM before the storage boots online for example. After upgrading to 8.3 I've realized that rc.local + vApps method does not work any more, can someone confirm that? I've found solution here: https://docs.xcp-ng.org/guides/autostart-vm/#with-the-cli , however since i was typing and not copy-pasting, instead of "xe pool-param-set uuid=<VM_UUID> other-config:auto_poweron=true" on the last part I typed in autopoweron:true, restarted and it does not work. I typed it with colon (:) again and listed pool param list, then i saw two "autopoweron:true" flags with same value, i decided to type autopoweron:false, then i had 3 flags, two true and 1 false... Later on I realised that i had to use equals (=), so now autostart works. Is this normal behaviour when using colon instead of equals sign? Please see picture attached: [image: 1785409860850-screenshot-from-2026-07-30-12-58-04.png] Also, is there a way to add autostart delay to VMs? Thanks!

    @poddingue Thanks for looking into it further as well.. If there is a hard cap on the amount of NBD connections, then that is very interesting. Because the closest I've ever been able to find regarding this setting, was the general answer of "Try and see what works for you". So if ther is indeed a hard cap, then I would propose that this is limited inside the GUI itself. e.g. if the cap is 8, then don't let the integer exceed 8. I'm doing increasing increments of the number of connections now. So far I've done 1,2,10. And 10 does seem to be breaking again, but only on some. Thanks as well for the link. I'm collecting the logs through xen-bugtool --yestoall now. I do wish that something like this is implemented in GUI someday. And I even made a FR feedback on it. Since I really do want to provide good information for the devs. But collecting manually isn't the most convinient way unfortunately. Logs should be up shortly

    Merci beaucoup pour vos retours ! @nathanael-h : C'est l'étape suivante !!! J'ai découvert cluster API le mois dernier et j'ai déja testé sur d'autres plateforme ! ça déchire !!! Je ne savais pas qu'il y avait un support de XCP-ng ! Je finis ma série d'article pour une installation classique et je bascule sur cluster API ! @ataxyanetwork Merci pour ton repo. Je vais regarder ça
