@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.

@Team-Storage I am also having the same issue. Here is link on my forum post: https://xcp-ng.org/forum/topic/12093/lost-connection-to-iso-repository/9

@yannsionneau Thank you very much. Please let me know if there’s anything I can help with.

So the scheduled backup at 1pm this afternoon ran with no issue.

Adding: is there a possibility to see the vm-export progress in the XCP-ng Center in a next update? Actually we only can see the vm-import progress. Thanks!

@olivierlambert I added this feature request in the backlog regarding RPU improvements.

@MajorP93 said: @florent Thanks! I did not have time (yet) to look into the heap export due to weekend being in between. I will update to current master and provide you with the heap export in the following days. Best regards no problem , the sooner we'll have these exports, the sooner we will be able to indentify what is leaking in your usage, since we already plugged the leaks we reproduced in our labs

@gleveque Hello Can you retry with an up-to-date XCP-ng 8.3 host? PCI expansion ROM are now enabled when doing pass-through. The guest VM can now access the ROM bar. Regards, Yann

@olivierlambert +1 For creating vApps GUI in XO Reason: I recently had this configuration: VM1 - Delay 90 Seconds VM2 - Delay 100 Seconds VM3 - Delay 0 Seconds The VM3 instead of starting first, always starts last without fail. One difference I noticed is that VM3 is UEFI vs VM1 & 2 being in BIOS mode. I read elsewhere in the forum that vApps is the only reliable way to have an order. Maybe if we can somehow ensure that delay works, vApps will become less significant ?

@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.

@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.

@abudef I don't know. I forwarded the question.

@ataxyanetwork I managed to install XOA (Current version: 6.2.2 - XOA build: 20251219) and did some more testing. I am experiencing the same issue when trying to restore from an existing backup. When I create a new backup job, I can perform a filelevel restore without any problems. However, when I rerun the job, I am no longer able to restore from the most recent backup. It only works with the initial backup. Can you also reproduce this ?

@Bytevenidos That's an interesting way of doing this, I'll have to remember it. I think the Fuel Ignition tool has a vhd output, it also produces both ignition and combustion parts for you. Worked pretty good on one test machine, but I need to go deeper into some of the other choices you can type in.

Hello @MathieuRA , @florent Moving the discussion to this thread as it seems to be tackling the same issue: https://xcp-ng.org/forum/topic/11892/xoa-memory-usage/28?_=1776334896974 I reported my findings so far over there Best regards

Thank you so much for your feedback, @Vagrantin !

@denis.grilli The problem is not the performance of the scan ... the problem is, that this storage device only consists of block devices (disks) that should go into standby mode when not used ... but I think I've found a code line that checks if other-config for an SR contains auto-scan: false... I think ...

@yannsionneau Thanks for the update! We are eagerly awaiting your findings! Thanks for looking into it.
