@acebmxer not yet (a little under the water with the release patch, but we will do it )

@Pilow I did check this and it definitely completes within the hour. I am testing a lesser value for CR retention to see if this resolves it.

So the scheduled backup at 1pm this afternoon ran with no issue. As stated previously the Coalesces are adding now now show 2 for vm. edit - Apr 21 11:22:55 xo-ce xo-server[15617]: }, Apr 21 11:22:55 xo-ce xo-server[15617]: summary: { duration: '6m', cpuUsage: '4%', memoryUsage: '29.01 MiB' } Apr 21 11:22:55 xo-ce xo-server[15617]: } Apr 21 13:00:00 xo-ce xo-server[16924]: 2026-04-21T17:00:00.320Z xo:backups:worker INFO starting backup Apr 21 13:00:00 xo-ce sudo[16938]: xo-service : PWD=/opt/xen-orchestra/packages/xo-server ; USER=root ; COMMAND=/usr/bin/mount -o -t nf> Apr 21 13:00:00 xo-ce sudo[16938]: pam_unix(sudo:session): session opened for user root(uid=0) by (uid=996) Apr 21 13:00:00 xo-ce sudo[16938]: pam_unix(sudo:session): session closed for user root Apr 21 13:00:06 xo-ce xo-server[16924]: 2026-04-21T17:00:06.941Z xo:backups:MixinBackupWriter INFO deleting unused VHD { Apr 21 13:00:06 xo-ce xo-server[16924]: path: '/xo-vm-backups/138538a8-ef52-4d0a-4433-5ebb31d7e152/vdis/9f7daac4-80a1-41f9-8af0-99b6fe> Apr 21 13:00:06 xo-ce xo-server[16924]: } Apr 21 13:00:19 xo-ce xo-server[16924]: 2026-04-21T17:00:19.536Z xo:backups:MixinBackupWriter INFO deleting unused VHD { Apr 21 13:00:19 xo-ce xo-server[16924]: path: '/xo-vm-backups/6d733582-0728-b67c-084b-56abe6047bfc/vdis/9f7daac4-80a1-41f9-8af0-99b6fe> Apr 21 13:00:19 xo-ce xo-server[16924]: } Apr 21 13:01:23 xo-ce xo-server[16924]: 2026-04-21T17:01:23.971Z xo:backups:worker INFO backup has ended Apr 21 13:01:23 xo-ce sudo[16971]: xo-service : PWD=/opt/xen-orchestra/packages/xo-server ; USER=root ; COMMAND=/usr/bin/umount /run/xo-> Apr 21 13:01:23 xo-ce sudo[16971]: pam_unix(sudo:session): session opened for user root(uid=0) by (uid=996) Apr 21 13:01:23 xo-ce sudo[16971]: pam_unix(sudo:session): session closed for user root Apr 21 13:01:24 xo-ce xo-server[16924]: 2026-04-21T17:01:24.029Z xo:backups:worker INFO process will exit { Apr 21 13:01:24 xo-ce xo-server[16924]: duration: 83708608, Apr 21 13:01:24 xo-ce xo-server[16924]: exitCode: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: resourceUsage: { Apr 21 13:01:24 xo-ce xo-server[16924]: userCPUTime: 31147905, Apr 21 13:01:24 xo-ce xo-server[16924]: systemCPUTime: 14319055, Apr 21 13:01:24 xo-ce xo-server[16924]: maxRSS: 65888, Apr 21 13:01:24 xo-ce xo-server[16924]: sharedMemorySize: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: unsharedDataSize: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: unsharedStackSize: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: minorPageFault: 367979, Apr 21 13:01:24 xo-ce xo-server[16924]: majorPageFault: 1, Apr 21 13:01:24 xo-ce xo-server[16924]: swappedOut: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: fsRead: 5648, Apr 21 13:01:24 xo-ce xo-server[16924]: fsWrite: 16101272, Apr 21 13:01:24 xo-ce xo-server[16924]: ipcSent: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: ipcReceived: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: signalsCount: 0, Apr 21 13:01:24 xo-ce xo-server[16924]: voluntaryContextSwitches: 65983, Apr 21 13:01:24 xo-ce xo-server[16924]: involuntaryContextSwitches: 7745 Apr 21 13:01:24 xo-ce xo-server[16924]: }, Apr 21 13:01:24 xo-ce xo-server[16924]: summary: { duration: '1m', cpuUsage: '54%', memoryUsage: '64.34 MiB' } Apr 21 13:01:24 xo-ce xo-server[16924]: } lines 617-656/656 (END)

@pkgw I tested it with a cluster size of 2 megabytes. I got similar results to those with the default size.

@TeddyAstie I do not have Citrix ones. This VM was pretty much freshly installed to test Windows2025 on as pure Vates-maintained stack as possible. Update: Please note my post above. Tha this seems to be triggered by live-migrating the vm

Thanks, Florent, for the explanation.

@Pilow @acebmxer Thanx for your replies. And sorry, i havent seen your first reply between my last posts with the link to your existing Thread. So, i think this is some kind of a bigger thing. Will handle with care, but i have to leave for today. Maybe i have time to test the snapshot and revert workarounds on the weekend. But these are all production VMs. Have to coordinate. I have 2 NFS-SRs in the Pool. Will try to migrate VMs from one to the other and see if this helps. Kind Regards and thx again Alex

@MathieuRA I noticed you merged https://github.com/vatesfr/xen-orchestra/pull/9787 I just tried it. And it does seem to fix my original issue! Thank you! I am always impressed by you guys. Making testing and reporting upstream (to you guys) a good experience! Elise-FZI opened this pull request in vatesfr/xen-orchestra closed fix(xo6): remove dev routes from prod #9787

@gregbinsd let us know. If you do use my script. It pulls nodejs from NodeSource so it may not install the latest 24.15.0 tls. If you specific 24.15.0 it will install that version. If you need to change node version with my script use the rebuild option.

perhaps "in the context of a proceeding RPU, do not start halted VMs" ? or "boot only halted VMs that have HA enabled" ? but I can imagine corner cases where this is not wanted. some chicken & egg problem.

@vlamincktr XO PROXY from source is pretty reliable at no cost either use @acebmxer script or @ronivay here is a quick tuto on an ubuntu VM https://omnibox.huducloud.com/shared_article/QJ9y1bRSPj9VTbWp6NKaV7yn/installation-xoa-a-partir-des-sources-github-ronivay first part is XO CE, second part is XO PROXY CE beware as you delegate some jobs to XO PROXY, to ever upgrade XO PROXY when you upgrade XOA, so that they have the same backup mechanisms/code

@Pilow Apologies for the late reply. Thank you for sharing the work around. I have tried it and confirmed that the work around works. I hope they can find a solution for this issue.

@dthenot said: @ccooke Hello, You should be able to make the XOSTOR SR work again if you update sm and sm-fairlock on the other hosts. yum update sm sm-fairlock Then you should be able to re-plug the SR on the master and proceed with the RPU. Hello, Had the same problem, the command resolved the issue. It needs to be run on every host. Everything is working fine again. However, I had to complete the pool update manually.

@ducatijosh did you do a yarn build ?

@McHenry I think depends if the copy is a fast clone, depending of full chain length with 13 points behind, or a full copy of its own that will be independant

@jvanabra "merge synchronously" option is there for log purpose. When you click on your backup job you can get all logs from this job here: [image: 1777971428328-78941893-5585-486a-b9bc-7d4c59873aa6-image.jpeg]

Xen Project covered this as XSA-489.

@acebmxer My take on those links: Nested virt is not currently supported by XCP-ng or Vates, but XCP-ng is committed to support nested virt at some time in the future.
