    @robertblissitt yup, afterward this seems to be a good best practice... my hosts were up for 4 month, and because of DNS resolution problem had 77 patches to catch up (80 for one with advanced telemetry enabled) a rolling reboot would have probably put in front the initial migration/evacuation problem (and subsequent zombies VMs) and no patches applied, and no pool in a semi upgraded state note to my future self, try a rolling reboot first.

    @Tristis-Oris There are many features missing since it's alpha now, but you can open bug tracker request on github if you want to keep track of progress for this particular feature.

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

    @uberiain at this point, when I am uninstall the old XCP-ng center software, and install the new msi, I just realized the xcp-ng keeps the settings file in Roaming folder. (C:\Users\user\AppData\Roaming\XCP-ng) When I deleted it I could re-register the servers.
  • IPv6 support in XCP-ng for the management interface - feedback wanted

    @psafont Sounds good on point #1. On point #2 I agree LLA shouldn't be the primary management IPv6 address on the interface, but you could run into trouble by not having a LLA address assigned at all. All of the IPv6 standards assume a LLA is assigned to an interface running IPv6 for things like NDP or RA to work ergo mysterious things could break as a result of an LLA address not being assigned. Just spitballing here, but if you're concerned that only an LLA would be assigned to an interface then perhaps there could be logic to disable IPv6 for said management interface if no non-LLA address is assigned, or IPv4 could be preferred if only LLA addresses as assigned?

    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/

    @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

    @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.

    On the VMware side, it's possible VMware doesn't set the right mode, so try to boot in BIOS or UEFI to see if it boots.

    This is the end for this nice and useful thread, as XCP-ng 8.3 is not a beta nor a RC anymore: it's a supported release now. However, we still need your feedback, as we publish update candidates ahead of their official release, for users to test them. Right now, there's a security update candidate which is to be tested. I strongly invite everyone who is currently subscribed to this thread to now subscribe to the new, dedicated thread: XCP-ng 8.3 updates announcements and testing, and to verify that their settings allow sending notification e-mails and/or other forms of notification.
