    @florent Thanks for your reply! We have started to migrate thousands of VMs, so disk transfer speed is important for us.. We will also do our detailed tests soon with different threads setting and publish it here. I think threads=1 is a good and logical default, but not efficient. Others might complain if you set it to a higher value. Configuration option would be a real good solution.

    @skipthompson81 said: this CONFLICT is not OK! You will need to provide more details about this specific backup job. It's possible that the backup succeeded, but then the subsequent Health Check failed or timed out. Have you tried downloading and examining the full log from the failed backup?

    Hello I'm pulling stats for all VMs to understand CPU usage. We're a bit behind the curve in terms of XO versions, but these questions hopefully are still relevant. If using a granularity of days, the interval is set to 86400 (understandably) but the endTimestamp varies. Running this on June 9th @ ~1740 we get timestamps for both Mon Jun 8 01:00:00 AM BST 2026 and Tues Jun 9 01:00:00 AM BST 2026. Does this average across the day? Why is the timestamp 0100? Why would there be different timestamps between VMs (all are running) and does that mean that the figures are misaligned in the results? These are retrieved via curl and a bash script, a bit hacky, but for clarity the request is: ++ curl -X GET -s -H accept:application/json -b authenticationToken=[[REDACTED]] -o [[REDACTED]] 'https://[[REDACTED]]/rest/v0/vms/[[REDACTED]]/stats?granularity=days' Really keen to know if we can control the start and endtime, as well as provide a manual interval, as well as the aggregation strategy (min, max, average). Are any of these possible? Lastly, is cpuUsage the percentage as per the dashboard, but averaged over all CPUs? Thanks so much in advance. James

    You have a problem on your XCP-ng, this is not related to a XO issue. It's stuck doing a snapshot, which is really a basic operation that shouldn't fail at all. Double check your SMlog on the host.

    It looks like I can remove the remotes and set them up again, and configure the backup jobs to address the new share. That's okay, there are not too many.

    You need one XOA, connected to both pools. It will stream the VM content (delta) from the source to the destination. You don't need any directly link between your SR in both DCs. You DCs can be isolated with just one XOA connected to both, and it will work.

    No XCP-ng/XenServer workaround, it's a "built-in"/by design limitation (it's considered as "stalled"). So your goal would be to avoid these extremely long tasks (ie: to finish before the task is destroyed)

    You'll end up with a chain, yes (so every read will need to make "hops" on each member of the chain). Longer the chain, slower the operation. But it shouldn't be too catastrophic either (for a heavily IOPS loaded VM, you'll notice the difference, but not in other less IOPS hungry scenarios)

    Sure, thanks. I'm using xoa and desktop app simultaneously. I hope that the desktop app will be available for long time.

    No, because those logs are useful in case of problem (to find a potential bug). However, they are garbage collected automatically (the oldest ones) after a while.

    All I can tell is that's not an usual issue. Never heard of problem of this kind before… So yeah, there is something weird. Could be related to NFS permissions maybe, or something between XCP-ng and your NFS host. It's not XCP-ng code directly, because otherwise everyone else using NFS will endure the same problems. So it's more a "combo" between XCP-ng and your NFS within your infrastructure. Please read the wiki on where to check logs (especially SMlog) to spot potential hints on where's the issue.

    @S-Pam Having a VIF for management and one for storage-traffic is a good solution, we do it that way to avoid crippling management during backups.

    Any ideas for a more elegant way than to write a script? For my point of view vApps should work without HA mode but unfortunately it doesn't work on my XCP-ng server. Only console/script start of the vApp using xe appliance-start uuid= "set here the uuid of the vAppp" is working. But it is again rework for the next XCP-ng version, I think manually set vices in systemd are not persistent through an update. Will vApp supported also in future? there are some discussions about it, if really needed.

    A soft reboot will try to migrate existing VMs (ie running on this host) to another host in the pool. Using Xen motion, so only if there is a shared storage. If it fails, then you need a force reboot, that will shutdown the VM, and then reboot the host.

    IIRC, we based the button in XO to do both modification at the same time when you set it up for a VM (in the pool if it's not enabled and in the VM). However, it's been a while I didn't check the code, I'll take a look to be sure
