@olivierlambert I feel like the cause of the timeout is what I posted here: https://xcp-ng.org/forum/post/107454 The incidents of the errors in syslog correspond by matching pool, date and time to the incidents of errors in XO backup. I've traced through several of these incidents in the syslog and matched them to the errors in the XO metadata backup and matched these to missing metadata backup files in the directory on the storage server (ex. 20260807T041000Z) which is created even if the backup fails. I would look in older logs to see if maybe this has been happening for a long time, possibly before an XO update now shows the error, but my syslog data only goes back 30 days. The XO metadata backup errors started over 30 days.

@dinhngtu Fantastic - thank you for thinking of and including that!

@TeddyAstie I think there's alot of interest in the Intel platform because of the lack of ridiculous licensing for virtualization features. The problem is that you need a pretty current 6.x kernel to use them and XCP-ng/XenServer is just stuck on a really aging kernel right now. As exposed in this thread, the PCIe pass-through isn't really working properly under XCP-ng. Even if pass-through worked, that's kinda lame because the real purpose would be to chop up the GPU into SR-IOV instances so multiple workloads could have a GPU. The Proxmox community is already rockin' and rollin' with this. I watched a video a couple of days ago where a B70 was chopped up into Qty.4, 8GB GPU's via SR-IOV and passed to clients. No ridiculous mega-$$$$ licensing. It just worked.

Check the output of dmesg -T|grep -Eiv 'guest|capacity|promiscuous' on the host. It's likely that there was a network disconnect at some point and you have a stuck mount. You could also check to see if df -h hangs when you execute it on the host.

@irtaza9 i would look a the usual suspect, /var/log/SMlog /var/log/xensource.log see https://docs.xcp-ng.org/troubleshooting/

@yllar Hello, We are still validating the ISOs, but we are getting closer to releasing them. We hope to make them available soon.
