    Thank you every visitors and for those who did not had the chance to visit fosdem check this report: https://xcp-ng.org/blog/2026/02/19/fosdem-2026-follow-up/ [image: vates-xcp-ng-at-fosdem-2026-1.webp] One question, I promised to forward to the forum, how many VM are you running on XCP-ng ? Dozen, hundreds, thousands or more ?

    @comdirect Use this command: (replace sda in the command below with the relevant device) cat /sys/block/sda/queue/scheduler The active scheduler will be enclosed in brackets. e.g. noop deadline [cfq] For multiple drives use: grep "" /sys/block/*/queue/scheduler

    @MichaelCropper My Truenas runs on bare metal, I have smb SR for iso, NFS SR for VMs, another smb for VMs. In production I have a second old Truenas that that has smb and nfs that I use for storage updates, migrate from faster to slower storage which is still generally enough for my needs, update Truenas, migrate back to faster. I also have a third Truenas that has user data, but it's big so I set up a backup remote smb to spread out my disaster footprint. In my lab is just a single bare metal Truenas with whatever kind of share I need. Generally just smh and nfs or iso and vm. Both systems run three XCP-ng hosts so I can do things like rolling pool updates with no VM downtime. RPU is genius, all automated, just click a button and watch VMs move and hosts reboot.

    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.
