One question, I promised to forward to the forum, how many VM are you running on XCP-ng ?
Dozen, hundreds, thousands or more ?
Update 2:
Renaming eth2 to eth6 and eth7 worked like a charm.
Had to do a fresh install because the emergency network restart didn't work.
it's hard to tell which PIF belong to each bond on XO (at least on source-compiled version), needed to use old xcp-center to figure it out.
This thread can be closed.
still having some network issues :S
@pilow
As I am completly new to this scripting and such I did reach out to Ai for assistance and believe the license check should be bypassed now.
Again not suggested to use in production. Use at your own risk.
still has its own branch for more testing before merging to main branch.
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.
