    @florent With CR running and NBD enabled for 2, I see both exports and one import (per disk). It's never the import that's stuck and only one (not both) of the exports (if it happens). I have updated XCP 8.3 to the new January 2026 patch and XO to current master and will keep an eye on it again.

    @florent, I had to do the same for Xen Orchestra Community Edition. In my case, config.toml already contained the [authentication] section, so adding a separate config.tokenValidity.toml file did not work. Instead, I had to modify the existing config.toml located at /opt/xo/xo-server. In my opinion, it is best to keep defaultTokenValidity set to 30 days as a fallback in case no value is specified. You can then simply increase maxTokenValidity to the duration you prefer. [authentication] defaultTokenValidity = '30 days' # default value of 0.5 years # comment out and increase to 5 years #maxTokenValidity = ' 0.5 year' maxTokenValidity = '5 year'

    @mpiton thanks for sharing docs, the crucial part was openssl rand -hex 32 my password was too simple and that's why i got :"Query authentication does not match server setting" error after setting 32 characters password i got my metrics, in both http://localhost:9004/metrics and http://<xo-ip>/openmetrics/metrics

    Oh okay, so it's not a NAT issue then (thought XOA and the host were not together). Might be this issue then, please comment in the GH issue you posted to report you have the same problem edit: with your log too!

    @dr4s1l-0 @Dr4s1l-0 you will not see the config drive mounted in your system, cloud-init only mounts it temporarily very early on in the boot process, copies the found config files off of it, and unmounts it. Mounting it manually will just cause more issues. You can probably see it being mounted early on in the logs in /var/log/cloud-init.log Cloud-init has introduced a ton of bugs this year and has no documentation regarding them, it has been a nightmare to try and track down these issues - I have a support customer with the same issue on recent versions of ubuntu and I've gotten nowhere. At this point I think it's best to take it up with the upstream project, cloud-init - from the XOA/XCP perspective we're doing everything we can, resulting in presenting a properly configured config drive - any issue after that is the cloud-init package

    What does the memory min/max settings look like in the advanced tab of those VM's? You could try to set the dynamic min/max to same values. Could very well be that your guest OS doesn't handle it properly when host is trying to dynamically adjust the available VM memory. Although this shouldn't happen (afaik) if there's plenty of memory available on the host, but worth a try at least.

    Hi, The Docker container isn't coming from us, so there's no way to know where is the problem. Please contact the 3rd party provider for this Docker repo.

    VDI Won't Coalesce (shows orphaned but isn't)

    So another odd thing I'm seeing with this VDI, it's showing the size incorrectly. It shows 180GB of 180GB used up (on thin provisioned SR, both the old and new are), however the VM is only using 140GB of that 180GB. Something definitely went wrong with this VDI during transfer, just not sure what. I will say that I increased the VDI size again and now it displays more accurately, showing 180GB of 185GB used (both in XOA and with vhd-util). Almost behaving as if this was at one point on a thick provisioned SR or something. Just to avoid issues I'm maybe tempted to create a fresh VHD, copy data to that, then delete this one.

    It's not only this code. But in general, a good way to manage that is: "every message in CAPS is coming from the lower layer" (ie not XO).
