You can build XO from sources and have full access to all. You may use my script if you like - https://github.com/acebmxer/install_xen_orchestra

I'm doing more backup runs. And not all of the VMs trigger the warning and fall back. But it seems quite random so far.
I did one adjustment thoug.
My number of NBD connections are set quite high, 20. And after reading this post I decided to try if lowering to 1 would have an effect. And it seems that it does. The latest backup-run hasn't showed any warnings this time... Maybe it's a false lead. But it is a behaviour I noticed this time
All hosts are restarted with 9.2.18 loaded now. Will see what happens next.

@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
