    @poddingue Wow, fantastic! Your time and efforts are most appreciated. And I'd be more that willing to have the contents put on the docs.xcp-ng.org site. I'm just pleased that the information still can be found useful and will be able to serve the community for some time to come. My only question is with these additions, is it possible to view the full articles similar to how the PDF and improved Word documents I hacked render that first article? I'm afraid I'm not savvy enough about Github to understand this. Many thanks again!

    @tjkreidl I found that some Intel PRO GPU card have SRV-IO without any additional license, but this functionality is supported in Linux kernel 6.12 and up. I hope in new XCP-NG will have 6.12+ and support GPU sharing.

    acebmxer said: I have issue with rolling pool update with 1 of my 3 pools at work. It was the last pool to be updated. Host 1 updated no issues. vms stopped migrated off host 2 to complete updates. Support ticket opened - Ticket#7758427. Found 1 vm with cpu stuck at 100% and unresponsive. Force rebooted vm and proceed updates on host2. Well I think i found the source of my problems. After having continues other odd issues with this remote pool. I decided i was going to reboot everything. That's when every vm started to fail. Logged into Synology rs1221+ and it was just very sluggish and not responsive. No new error alerts or anything to explain the odd behavior. Rebooted it and even after boot still odd behavior until finally disk error. Then the system started to respond. Luckily I have a spare drive onsite but cant gain access until Monday possibly Tuesday. Fingers crossed. Lucky for backups. Looks like the important vms had a successful backup as of yesterday so thats good.

    @iams3le we have switched to the signed xcp-ng drivers. We also replaced our older 2022 servers.

    @Rod-G These have 9.4.2-xxxx and I need to go through and update everything now that I see how far behind I am. the second VM completed fine after its reboot, something was just stuck in a dirty state and got in the way of the import or health check.

    @Danp I was going to do the upgrade over the December / January Christmas break in Australia but that is when this issue became apparent so we didn't want to be making major changes until it was resolved. I note @anthoineb noted the first report was late August / September 2025 which was just before 8.2.1 reached EOL, so it would be a shame not to have a fix for it tested on 8.2.1 as it seems an upgrade to 8.3 would be unwise while we still have this issue?

    @florent said: where does this disk comes from From my Redhat 10 @florent said: if you have access to your SR from the outside, you can also put the qcow2 file directly I create a VM to be a NFS to access the 3 HDs, the qcow disks are on the Redhat 10 that I was trying to import from. Do you mean I put the qcow disks on one of the HDs and access them when I create a VM?

    @pierrebrunet sorry for the delay in responding... I scored some time out of the office. Before replying, I rebuilt the XO server using the latest version and created a new backup identical to the last. Just wanted to be sure this issue wasn't fixed... I've attached the log. 2026-05-20T21_41_04.958Z - backup NG.json.txt

    @Danp fully patched 8.3 (through the most recent May patches). XO commit d810e (master commit e3a58). I usually update XO around the first of each month; so it's a little bit behind master. There are crash logs in /var/crash. I can provide a log bundle if needed, or copy/paste some info here if I know what to provide.

    @yannsionneau @thierryescande Thank you very much for the updates! We are scheduling some downtime on the services in the upcoming weeks, then I hope to be able to try out all your suggestions. Our fallback plan is to switch the Broadcom network cards for other Melanox cards. I will be posting the results once we have them!

    The sr.scan-driven SMlog growth angle that gumbo2k surfaced is a real lead; there's some context in the storage-related log files reference, but the docs don't go as far as "here's how to throttle it safely on a pool where the underlying disks should spin down." Soft ping to @Team-Storage and @Team-Hypervisor-Kernel: could one of you weigh in on whether other-config:auto-scan=false on the SR is the supported way to reduce scan pressure, or if there's a better lever? I don't want to send anyone down a path that breaks an SR. Apologies if this has already been answered somewhere I haven't seen.
