        @rzr Since the targeted test window is over by now, I wonder: what are your plans regarding this set of patches? Will it be released soon?

          yes this is the plan, we're a bit slower this time because the iso publication is a longer process, but afaik no issue are spotted so far, thank you for your patience.

                    Installed these patches on a pool of 4 hosts, can confirm everything looking good!

                      Just installed these onto my test systems including my twinstor guinea pigs and all seems good so far.

                          Ran into some issues with sdncontroller.py (XCP-ng 8.3 and xcp-ng-xapi-plugins-1.16.0-1) when creating traffic rules on VLAN VIFs (and networks) in XOA — same error on both Premium and Community. The problem turned out to be a line feed sent by XOA.

                          On line 236 of sdncontroller.py, I added a fix that solved the problem, and it now works perfectly managing traffic rules in XO on VLAN networks:

                          def update_args_from_ovs(args):
                              # FIX: strip line feed (\n \X0a) sent by Xen Orchestra
                              args["bridge"] = str(args["bridge"]).strip()
                              # get parent...
                          

                          I had another problem when adding rules on networks that weren't connected on all hosts, because those hosts didn't have VMs running on that network (default). Manually connecting them worked fine.

                          I think it's more of an XO error than xapi plugin, but worked ok in my case.

                          Thanks for the great work!

                            Ah good catch @andersonalipio ! We'll check that 🙂

                              @andersonalipio I would be interested to get some elements from your installation.

                              • your /var/log/sdn-controller-plugin.log file (on the host) in order to check the parameter passed by XO.
                              • output of xe network-param-list uuid=$UUID (for the network concerned) or xe network-list params=all (if uuid is unknown)
                              • output of xe pool-list params=other-config (for xo:sdn-controller:* elements)
                              • output of xe vif-list params=uuid,network-uuid,other-config (for xo:sdn-controller:* elements)

                              Feel free to share it privately via PM if you prefer, possibly using https://paste.vates.tech/ .

                              Cc @Team-XO-Backend too (as it could be from XO side)

                                @andersonalipio can you also share the XOA version you're running? @semarie did a bunch of improvement on lifecycle of hosts and VM at some point XO side.

                                  @semarie I'll do it as soon as I get access to the server, hopefully tomorrow.

                                      this output is pointless because our current rules are on network, not on VIF anymore.

                                          Hello,

                                          We have just made "refreshed" XCP-ng installation ISOs available for everyone; these include all updates released over the past year, up to the present day.

                                          You can read the blog post here: https://xcp-ng.org/blog/2026/08/14/xcp-ng-8-3-lts-refreshed-installation-isos/

                                            New maintenance update candidates for XCP-ng 8.3 LTS

                                            This release batch contains mostly fixes, tool version updates, and some improvements.

                                            What changed

                                            Virtualization & System

                                            • kernel:

                                              • Reliability fixes for CVE-2026-45840 and CVE-2026-53227.
                                              • On some systems, PCIe expansion cards connected to a hotplug-capable PCI bus might not be seen at boot time. This release fixes such systems.
                                              • Fixed CVE-2026-64600, also known as RefluXFS. By default, XCP-ng doesn’t use XFS; when an XFS SR is used, we consider the LPE risk low, but fixed it anyway as a defence-in-depth measure.
                                            • xen:

                                              • Synchronization with XenServer release 4.17.6-12:
                                                • Various XSA fixes that were already included in XCP-ng previous releases are now part of this XS release.
                                                • It also brings fixes for possible bugs and crashes.
                                              • Fix bug causing UEFI logic to set inappropriate screen resolutions.
                                            • edk2: Add XCP-ng branding to the UEFI VM boot logo

                                            • varstored and xcp-efivar-utils:

                                              • Sync with XenServer 1.3.4-2.
                                              • Group existing EFI helper scripts into a shared package xcp-efivar-utils.
                                              • Update dbx hashes from secureboot_objects v1.6.5.

                                            Test on XCP-ng 8.3

                                            yum clean metadata --enablerepo=xcp-ng-testing,xcp-ng-candidates
                                            yum update --enablerepo=xcp-ng-testing,xcp-ng-candidates
                                            reboot
                                            

                                            The usual update rules apply: pool coordinator first, etc.

                                            What to test

                                            As usual, normal use and anything else you want to test.

                                            Regarding this sm update, please check whether the SM logs show any crashes related to the GC, particularly on NFS SRs, and send us these logs if there are any issues.

                                            Test window before official release of the updates

                                            ~ 4 days

                                            We would like to thank users who shared feedback since our last call for testing:
