Mine was working on the latest commit however tonight due to a power failure my XO VM rebooted and now i too am experiencing the same errors. My hosts also rebooted as a result. Rolled back to a build from earlier this month and all is well again.

Great news Closing this as fixed. Thanks everyone for your feedback!

came across this topic.. i have exported a vm and trying to import it to another xcp. I had issues with the migration so i tried export and import and i have this error HTTP handler of vm.import undefined { "code": "IMPORT_ERROR_PREMATURE_EOF", "params": [], "url": "", "task": {

@olivierlambert @olivierlambert said in OVA import failing: Keep in mind the file has to flow from your browser toward your XOA, then to your XOA to your host, which might use another network share itself. If your XOA could mount the place where you have your OVA directly, you could use upload-ova utility (see https://github.com/vatesfr/xen-orchestra/tree/master/%40xen-orchestra/upload-ova#usage ) to send them directly. Going to look into that, thank you.

@ThierryC01 said in XCP-ng Windows PV Drivers 8.2.2: Why is there no video drivers for Windows, I have a Windows 10 Pro VM and the video lags a bit compared to my Linux Desktop VMs despite having 8GO RAM and 16MO (?16 max???) video memory. Because it's rudimentary GFX and has no acceleration at all. It's not made for what you might expect.

@darkbeldin For the record, both vm's were running on the same esxi host when exported. This may or may not be a factor (I suspect it is).

It's also explained very clearly here: https://xen-orchestra.com/docs/community.html (in the first point) Always update to latest code available before reporting a problem

We don't have any other report of this issue elsewhere. Double check you are on the completely latest XO version, and alternatively, try with XOA on latest channel.

Thanks for your input! I think it might be the one then Also, if there is a big problem with it, we can always update the package!

@olivierlambert we are thinking about implementing a relationnal DB in the future. Maybe it could offer to stock snapshots as "archived"... I don't know for now. I understand that it could be risky to delete old snapshots, and maybe the responsability of setting the snaspshots retention can be an ACL subject... There are plenty of avenues of work on this topic, and more generally on the retention of information about objects, tasks, and other actions. It's a real in-depth topic.

@Mark-C Wouldn't have made it without your help! Super. So far everything seems to be working normally, except for my original issue on the other topic, posting there now. If any more issues come up I'll post them here and reference on this topic. Many thanks!!

@fohdeesha lol :-). ok.... good to now :). Next optimization by decoupling harddisks and fans.... and always be quite on the datacenter :).

Perfect! Enjoy

@mohammadm i think for nfs you should handle that from the kubernetes side. i.e. use an nfs-provisioner or the built-in nfs storageclass

that log appear again, without any actions from my side. [image: 1713513115366-bab449b6-55cb-4e9f-b0af-ce8e9bb19d22-%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5.png]

@Raymondello you right, the issue is from the storage and I am looking into that. Thank you for sharing the UAT Testing, I didn't know about it

its still there ie the host is still atached to that vdi im thinking this is the issue why my backups wont run anymore if not i will do it on the xen server cli, but it would be nice to know why this isnt working

@hoerup Hi, I can't remember too much to be honest. I created a Debian 10 VM with 20GB disk, set up all the stuff that needed to be common for the Ceph pool pretty much following the Ceph documentation using the cephadm method - so Docker etc. This would be my 'Ceph admin VM' Once that was all sorted I cloned the VM 3 times, for my actual Ceph pool and changed the hostname and static IP etc. I've got 3 hosts with Supermicro boards that have two SATA controllers on board, so on each one I passed though one of the controllers to the Ceph VM and then just deployed Ceph and followed the documentation. The only issues I ran into and any other tips are in the other post I linked to. Now Ceph is all containerised it all seams a bit too easy! Hope they're not my famous last words!! It does like a lot of RAM, so I've reduced the OSD limits down a bit and its fine for me. Cheers.

Hello dear RC testers! We are releasing 7.5.0 final today, so here's how to go from 7.5.0RC to 7.5.0. Warning: this is only for people who installed the RC. Detailed procedure will be given in the release announcement for upgrading an XCP-ng 7.4 server Option 1, upgrade using the installation ISO Will work, although may be a little overkill since you already have a nearly-final 7.5.0. Option 2, update yum repository files and update the system # remove the RC-specific repository file if present rm /etc/yum.repos.d/xcp-ng-7.5.repo -f # install the 7.5 official repository file wget https://updates.xcp-ng.org/7/xcp-ng-7.5.repo -O /etc/yum.repos.d/xcp-ng.repo # update. If you had updated your RC regularly, this will install nothing, else you'll get a few packages yum update # if the kernel or xen-* packages got updated, reboot your server # that's it, you've got 7.5.0 final!

@AshleyDe In the last few days, I've had these same issues with a few Server2025 virtual machines (I assume are close ish to Win11 24h2).
