@MajorP93 I am currently working on this issue but to answer you quickly, yes we have automatic tests, unit and integration tests (you can see them in *.integ.mjs and *.test.mjs files, and @xen-orchestra/qatest folder), a long QA to validate at each release. We add a regression test at every bug we encounter. The issue is we could not reproduce your exact issue yet.

It's possible that you hit this known issue.

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
