    @ronan-a we need to have CBT to use 3rd party backup & replication solution such as Veeam. On the other hand, XOSTOR with VHD disk might be ok using Xen Orchestra backup & replication features but it needs more testing on our end to make sure it works good enough. One big question is about the snapshot chain. Coming from VMware world where keeping snapshots may impact I/O performances, we're not very comfortable with it. Also, we need to find solution for low-RPO replication. On our VMware infrastructure we use Zerto DR for this but XOA being more like Veeam using snapshots, low-RPO will be tough to achieve (unless making snapshots doesn't affect performances at all ?).

    Resolved. Patched the rest of the hosts. Restarted all the toolstacks for good measure. I can move the master role now, and deploy new VMs.

    There are any commands that allow me to verify the integrity of the backup files?

    @cbaguzman for information, I made some changes on vhd-cli so in the future we'll get a more explanatory error message when a command failed because we passed an incorrect argument: https://github.com/vatesfr/xen-orchestra/pull/9386 b-Nollet opened this pull request in vatesfr/xen-orchestra closed feat(vhd-cli): prevent using invalid options #9386

    @florent "the export is done by one of the host of the pool" How is this host selected ? Is it the master one, the one hosting the VM, or the less busy one in case of shared storage ?

    @olivierlambert Client is a proxmox shop and whilst tolerating services running in XCP-ng / XO world they require that if everything fails they have the ability to pick up the pieces in-house. Proxmox has easy import of .ova but very manual process for .xva hence....

    @Pilow the rrd ( the stats ) use the same code path as the backup . I am not sure if it's a feature or a bug, but at least it's a good canary the data volume of stats can be quite huge and have an impact on management. So it's a little justifiable to use the same network for backup and stats, at least until we can separate things more clealy . At least it helps a lot to check if the network is really reachable (sometimes because of third party filtering or ip configuration error , other to the xoa missing some network), and the downside is not to dangerous.

    Yes but why it works with some and not others. I suspect the firmware version in the NIC itself.

    I also added windows build so that people can help with testing also on windows. It's a static build, no need for installer, just single zipped .exe file. No dependencies.

    If I remember some previous discussions, EVE-ng uses some features that doesn't work in nested mode with Xen.

    @wlp94114 said in Intel x710-t2l Problems: The x710 series has a reputation for being picky about driver and nvram versions. Out of curiosity, is there anything reported by the linux driver that would allow make the situation obvious?

    @irtaza9 it scans all the VDI's on the SR to see if something has changed, if there's a need for coalesce and so on. I dont think it will be a big issue if you increase the auto-scan-interval value to lets say 5 minutes (300 seconds), but do remember, that everything regarding the VDI's on the SR will take up to 5 minutes to update, as well as triggering coalesce after removing snapshots.

    @Pilow Does disk show up after you do the snapshot? If it is able to do the snapshot there is a high chance it can boot up. So try booting up (and check for disk) and shut it down and do the snapshot at that time if the disk show up. It helps to boot up on the old v5 commit and check from that side too if you have both copy before the commit update. Yep I can confirm that snapshot doesn't always work. But using the older v5 that used to work before the update does get it showing up on the newer v5 commit if I go through whole snapshot, revert, etc. one of those case work.

    @andSmv I definitely think it would be nice with support even though i repurposed my M2 Coral for other uses. But one thing to keep in mind regarding resources is that the product would appear to be heading to https://killedbygoogle.com coral.ai redirects to their new NPU offering and no updates have been made from google to the driver since 2022... Mouser still has plenty of stock though. Frigate.nvr which is one of the popular uses for the Coral do not recommend it for new installs either.

    We are not energy efficiency experts, while EasyVirt people are. I think they already have some stuff and it might be just a matter of plumbing.

    Thank you! So in this case, if better option for me to join the hosts to existing pool and then shutdown VMs and start it on host with older CPUs. Thank you again!
