    @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.

    Hi @pierrebrunet. I have deleted the "parentless" VDIs and snapshots. So the "Unhealthy VDI" page is empty for me. So everytime I retry with the VM in question it is creating a new (full) backup-chain. Regards, Marc

    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

    Hi! I suppose you mean XOA? And yes, you can, until we have a UUID bind per XOA.

    The information is visible in the build number you have in your XO section. The build number will be visible in the latest appliance once deployed. Because it's not mandatory to use the last one, we don't track it. As I said, it's not a problem to update it until we ask people to change it

    Right now there's no way to know what's happening inside a VM disk. So we can't know when a VM disk is full or not.

    I had similar problems in 8. Even though I had static leases set in DHCP, oftentimes services come up before the IP address has been obtained. The physical console and SSH worked, but not XOA nor XCP center. Set a static IP address and reboot. If that does not work, repeat the installation and set a static IP at install. Make sure your IP address has not changed and look at the lease time. Is it only leased out for a few minutes? Here is where we discussed it for version 8: Broken Host Consoles in fresh xcp-ng 8 installation. VM consoles work.

    Hi, No. Using UUIDs is vital to have consistent files (if you change the VDI or VM name etc.) Any XO, even a fresh one, is able to connect to your remote and restore your backup. So there's no need to access files directly.

    How to save Statistic from XOA when rebooting the XCP-NG Nodes?

    It should be the same result on XCP-ng Center: it uses RRDs files stored on the host. Why do you continue to talk about the after the reboot? You mean after the upgrade, right? RRDs are preserved after a reboot If you do a yum update, those stats should be in theory preserved. If it's not the case, try to diagnose why, by comparing behavior between XCP-ng Center and XO. If it's not the same, then it's a client issue. If it's the same, then it means a version upgrade (yum or ISO) won't preserve RRDs. If you really want long terms stats for "real production" usage on long term, I strongly suggest that you think to store them in a real time series database, like Prometheus or so.

    @dbeato Update on this. Basically I needed to run the Updates on the XCP-ng hosts even though they were on 8.1 and upgraded 5 packages. Once I did that since I had an Updated XOA system, then I reboot the servers and XOA and now backups are running!

    Nothing. You should have the stats visible in live (post-upgrade). That's it. If you don't, it might be because your nodes are behind a NAT.

    You can, but as I said, in this case, you'll need to move the storage with it. Unlike with a shared storage, where only the RAM is migrated between 2 hosts. So RAM only migration is really faster than storage motion, especially true if the VM is using a large disk.
