One question, I promised to forward to the forum, how many VM are you running on XCP-ng ?
Dozen, hundreds, thousands or more ?
The thing is that it works very well and doesn't need fixes… I know, not usual right? It was so stable that we left it like that waiting for people coming for bugs and nothing happened… We'll cut a 1.0 in the next weeks/months.
@mjr99 I bypassed it weeks ago. Didn't have to downgrade netbox. At the time. I upgraded to the latest Xo from sources. Then netbox worked. I shall be upgrading xo soon again
Thank you all.
Difficile de parler de « réalité » avec les benchmarks. Vérifiez aussi l'iodepth (qui dépend du type matériel que vous avez, sur du flash/NVMe vous pouvez monter à 128 ou 256), la latence entre en compte aussi bien sûr.
Le bottleneck principal est le monothreading de tapdisk, si vous testez sur plusieurs VMs différentes la somme va monter de manière assez régulière.
