@psafont thats good to know the system will prevent you from uploading the same ISO. Since my latest testing i cant seeem to get XO-CE to show the incorrect file name .img of the iso that was uploaded. But know @plaidypus is not alone in this as I have seen it myself and that is why you will see most of the iso in the picture have a date just a few days prior to this recent testing. I manually deleted the iso that were .img and manually uploaded the ISOs again.

just a personal opinion I'm leaving here, no follow-up needed. If I want to run containers I use OKD. I've always seen all the comments about keeping the dom0 controller to a minimum, docker alone adds a 2GB overhead to it, no more problems in adding stuff to it.

Thanks for the feedback @mathiashedberg !

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.

@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!

@m4rCsi Very nice, thanks for sharing the repo. We will defintely look carefully as we are also working on writing a XO CSI Driver. Ping @Cyrille

@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 :).

@olivierlambert While VDI is maybe not as vital as it once was...I'm experimenting with multimedia work in XCP-ng. Having a VM with GPU off-loading of CODEC encoding would be nice. It's a pretty big CPU hit to make that go.

Perfect! Enjoy

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
