      @nikade You can even see that Dom0 VM has 16 vCPUs and host has 40 CPUs, in my case anyway. So Dom0 sees just some chunk of host resources.

      Is there any intent to publish the latest xcp-ng 'release' with an XOSTOR iso ? There's an iso for the non-XOSTOR version (xcp-ng-8.3.0-20250606.2.iso) released on 18 Dec 2025, but the latest iso with xostor comparability is xcp-ng-8.3.0-20250616-linstor-upgradeonly.iso released in 16 June 2025. Reason for asking is the last incremental upgrade on 18th Dec partially failed on our pool master and so we need to do a 'clean' upgrade, however there are XOSTOR disks on that machine, and doing a network upgrade after a partial failure and regardless with xostor - is not advised / achievable. Thank you!

      If you look at the metadata files on the backup remote, you should see two files: data and metadata.json. Search either of these for the term "xapi_build", and that should let you know the version of xapi that was active when the backup was made. With this additional information, it should be possible to calculate which updates to apply to your host.

      That's also because XO Lite is replacing basically "nothing before", while XO 5 is 10y full of features that we can't all re-implement at once in XO 6

      not better with production upgraded to 6.0.1 (XOA and XO Proxies) we will open a support ticket ps : if we delog/relog from XOA with another user, we have better chance to get the file restore working... not 100% very unstable is there a link ?!

      Ah indeed, labels are honored even in the case of a warm migration. We used it ourselves when we migrated from Intel to AMD CPUs, it was really the best compromise betweeen live and cold (especially when you change the CPU vendor). Glad to see it's helping many people and companies now

      @McHenry Turning off the Manage via Windows update first + tools uninstall + reinstall should take care of it.

      @dinhngtu I believe it was changing the guest TSC Mode that seems to have done the trick.

      Because doing an update without rebooting doesn't reload the updated main programs, like XAPI. A host in only updated after a full reboot.

      @olivierlambert said in Xen Orchestra Node 24 compatibility: Can you reproduce the issue on XOA? Or it's only on the sources + your current OS? We do not have a XOA license (yet) which is why I am currently solely using XO from sources. Therefore currently not able to reproduce on XOA. OS is Debian 13.

      Pinning CPUs to dom0 - Does it really make a difference?

      @hitechhillbilly no it doesn't, it just ensures the N-th vCPU of Dom0 only runs on N-th pCPU of the machine. Not sure about the practical impact of it, in the past it has been used for getting meaningful CPU temperatures from coretemp (with physical core matching virtual one), but that doesn't work anymore since Xen filters MSR accesses (including Dom0).
