      Well, I'm not seeing the same behavior here, fe80::4496:9d87:690d:ccc7 is collapsed, unlike in your screenshot 🤔

          This seems to be specific to XenServer guest agents?

            I'm now back with better information from the original pool.

            xe vm-list uuid=0513005e-3626-1867-306d-9d5415cd6516 params=networks
networks (MRO)    : 0/ip: 192.168.97.60; 0/ipv4/0: 192.168.97.60; 0/ipv6/0: fe80:0000:0000:0000:a57c:c544:3b03:8910

            I will apply latest updates to see if this has any bearing on the matter.

              After applying latest updates and commits, to both xcp and XO. The zeroes were still non-collapsed.

              However. Rebooting the VM resulted in the zeroes now collapse properly as expected.

              I had previously rebooted the VM, so I don't believe that was the solution. But I did not check inbetween pulling latest source, and updating XCP. So I'm unsure which update solved it.

              But this then has been resolved.
              Update: Not solved! Now on fully updated XCP & XO, and the VM being rebooted as per post-details above.

                @jr-m4 Could you check if your VMs are using XenServer or XCP-ng tools?

                  They are using the vates provided xcp-ng guest tools.

                    I have now tried updating to the latest version included in the xcp-ng guest-tools.iso. Followed by a reboot.

                    At the moment, the zeroes are collapsed. But I won't count my chickens before they've hatched. So I will reply back if they expand out again (as seen before).

                    Thanks!

                      I believe I have a reproducible method to make it expand.
                      The trick aparently is Live migrating the VM.

                      After reboot

                      Pre live migration:

                        Do you have multiple guests agents in the VM (e.g Citrix and XCP-ng ones) that may step on each other for this IP ?

                          I do not have Citrix ones. This VM was pretty much freshly installed to test Windows2025 on as pure Vates-maintained stack as possible.

                          Update: Please note my post above. Tha this seems to be triggered by live-migrating the vm
