@dinhngtu Something called "Elpha Secure" ...none of our other antivirus shows it being bad but I wanted to ask around before I unflagged it.

@michael.manley Would it be possible to backport the XSA-498 fixes? I've tried updating the SDK as a whole but it resulted in a lot of churn and caused errors elsewhere: https://github.com/xcp-ng/xenadmin/pull/271 The fixes to the SDK have been posted here https://github.com/xapi-project/xen-api/pull/7176 and here: https://xenbits.xen.org/xsa/advisory-498.html

mid 2026: you can't add a ipv6 address via XOA (XOA5) because the gui lacs the field for the v6 gateway-address XOA6 lacks feature to configure ips of the host the configuration of ipv6 (static) vie the "gui" on the host seems not be implemented yet (or i am missing something critical) command line configuration inside dom0 of the host is afaik not supported ? Some point looks like minor issues. it would be great to "address" pun intendet that as well

@olivierlambert said: I'm not sure it's a great idea, because even 64 hosts is huge in terms of VMs and fallout if you have a problem on your pool DB. Even if you drastically improve the current mechanism, the impact of a problem pool wide is far bigger with 64 hosts than 24 for example. It's more than purely tech, it's also a tech design/choice. Exactly, the failure domain just grows exponentially when going beyond a certain collective pool size. I was doing some more research and I found a few possible choices that Tesco may have moved too, but don't want to detract from this forum here.

@pkgw I tested it with a cluster size of 2 megabytes. I got similar results to those with the default size.

@benapetr said in New project - XenAdminQt - a cross-platform GNU/Linux, macOS, Windows native thick client: you can switch between them nope, that just 2 from multiple nics. Need press add ip address to add other NICs. Now i see how it works.

Thank you every visitors and for those who did not had the chance to visit fosdem check this report: https://xcp-ng.org/blog/2026/02/19/fosdem-2026-follow-up/ [image: vates-xcp-ng-at-fosdem-2026-1.webp] One question, I promised to forward to the forum, how many VM are you running on XCP-ng ? Dozen, hundreds, thousands or more ?

If I remember some previous discussions, EVE-ng uses some features that doesn't work in nested mode with Xen.

XCP-ng 8.2 has just reached its end of life, but the adventure continues with XCP-ng 8.3 (and other versions to come). You can read the communication on this point on our blog: https://xcp-ng.org/blog/2025/09/16/xcp-ng-8-2-lts-reached-its-end-of-life/ To continue benefiting from updates and developments, we invite you, if you haven't already done so, to upgrade your systems to XCP-ng 8.3. A relevant thread has been around for quite some time if you want to participate in early testing of the updates: https://xcp-ng.org/forum/topic/9964/xcp-ng-8-3-updates-announcements-and-testing/

Yes, the old method should work

@TrapoSAMA All of mine are 2022, but saw this in previous driver versions with 2025. Low priority on this so I haven't fixed it yet.

@dinhngtu Thanks and good point. After my previous post I did stumble across some info (can't find the links) that suggested something similar. If I'm remembering correctly, the basic idea was the flash/NVRAM memory on the motherboard, which stores boot entries, is limited. If it's full, it's possible / may be necessary to do some cleanup using the bios itself or utilities available for Linux (efibootmgr) and Windows (bcdedit). I've not tried this myself as our install is working properly, but perhaps that can help someone else in the event they stumble across this particular issue.

@Danp Oh thanks, that makes sense, though I am not sure how I got it to work in the POC... Cold migration will be fine for the time being anyway

@yllar Maybe it was because of the loopdevice not being completely created indeed. No error for this GC run. Everything should be ok then

@MW6 You've lost two disks in a single array, you're data is lost. Time to restore from backup.

@olivierlambert The only place running XCP-ng on things like an RK3588 make sense is for home lab stuff, I probably wouldn't even build work lab stuff on these. Never enough ram (so far) and limited cores, plus almost everything will need to be running in virtual processor architecture. All that said, it might be neat to simulate these ARM processors in x86 so that we could create a VM of the Pi, etc.
