      @dthenot No worries, just wanted to make sure I understand the expected behavior when I had the qcow2 patches installed.

        @bufanda You just need to make sure to have a sm and blktap qcow2 version.
        Otherwise, having a normal sm version would drop the QCOW2 VDI from the XAPI database and you would lose VBD to VM aswell as name of VDI.
        So it could be painful depending on how much you have 😬
        But in the case, you would install a non QCOW2 sm version, you would only lose the QCOW2 from DB, those would not be deleted or anything. Reinstalling a QCOW2 version then rescanning the SR would make them re-appear. But then you would have to identify them again (lost name-label) and relink them to VM.
        We try to keep our QCOW2 version on top of the testing branch of XCP-ng but we could miss it 🙂

          @dthenot Only have 2 Test VMs currently not running with qcow2. Nothing production and nothing crucial. It's a lab pool. As I said just to understand the behavior when I test the new updates. But thanks for the details. Really appreciated

                  I think this is after the new update

                  Processor : AMD Ryzen 7 7840HS

                    Hi,

                    It's just an ACPI error, it shouldn't be a problem.

                      I agree. But just thought I should report nevertheless.

                      Update: This seems to be related to 7840HS motherboard. I tried it on another AMD Ryzen 7945HX but did not get this error.

                        It's clearly due to the motherboard, yes. Mostly buggy BIOS/UEFI and ACPI tables. This world is like the far west.

                          New security and maintenance update candidate

                          A new XSA (Xen Security Advisory) was published on the 8th of July, related to hardware vulnerabilities in several AMD CPUS. Updated microcode mitigate it, and Xen is updated to adapt to the changes in the CPU features. We also publish other non-urgent updates which we had in the pipe for the next update release.


                          Security updates

                          • amd-microcode:
                            • Update to 20250626-1 as redistributed by XenServer.
                          • xen-*:
                            • Fix XSA-471 - New speculative side-channel attacks have been discovered, affecting systems running all versions of Xen and AMD Fam19h CPUs (Zen3/4 microarchitectures). An attacker could infer data from other contexts. There are no current mitigations, but AMD is producing microcode to address the issue, and patches for Xen are available. These attacks, named Transitive Scheduler Attacks (TSA) by AMD, include CVE-2024-36350 (TSA-SQ) and CVE-2024-36357 (TSA-L1).

                          Maintenance updates

                          • http-nbd-transfer:
                            • Fix missing import exceptions in log files.
                            • Fix a potential HA startup failure with LINSTOR.
                          • xo-lite: update to 0.12.1
                            • [Charts] Fix tooltip overflow when too close to the edge
                            • [Host/VM/Dashboard] Fix timestamp on some charts

                          Test on XCP-ng 8.3

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

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

                          Versions:

                          • amd-microcode: 20250626-1.1.xcpng8.3
                          • http-nbd-transfer: 1.7.0-1.xcpng8.3
                          • xen: 4.17.5-15.1.xcpng8.3
                          • xo-lite: 0.12.1-1.xcpng8.3

                          What to test

                          Normal use and anything else you want to test.

                          Test window before official release of the updates

                          ~2 days.

                            And fixes for XCP-ng 8.2 are coming but they require more work to backport the patches.

                              Tested on my usual Intel test servers you've seen me post in this thread in the past as well as a 2 host AMD Epyc pool,(HP DL325 Gen10) rolling pool reboot worked as expected, hosts rebooted without issue, backups and replication appear to function as usual.

                                  Installed fine. Didn't get a chance to deep dive and/or test features.

                                       One of the configured repositories failed (XCP-ng Updates Repository),
                                       and yum doesn't have enough cached data to continue. At this point the only
                                       safe thing yum can do is fail. There are a few ways to work "fix" this:
                                      
                                           1. Contact the upstream for the repository and get them to fix the problem.
                                      
                                           2. Reconfigure the baseurl/etc. for the repository, to point to a working
                                              upstream. This is most often useful if you are using a newer
                                              distribution release than is supported by the repository (and the
                                              packages for the previous distribution release still work).
                                      
                                           3. Run the command with the repository temporarily disabled
                                                  yum --disablerepo=xcp-ng-updates ...
                                      
                                           4. Disable the repository permanently, so yum won't use it by default. Yum
                                              will then just ignore the repository until you permanently enable it
                                              again or use --enablerepo for temporary usage:
                                      
                                                  yum-config-manager --disable xcp-ng-updates
                                              or
                                                  subscription-manager repos --disable=xcp-ng-updates
                                      
                                           5. Configure the failing repository to be skipped, if it is unavailable.
                                              Note that yum will try to contact the repo. when it runs most commands,
                                              so will have to try and fail each time (and thus. yum will be be much
                                              slower). If it is a very temporary problem though, this is often a nice
                                              compromise:
                                      
                                                  yum-config-manager --save --setopt=xcp-ng-updates.skip_if_unavailable=true
                                      
                                      failure: repodata/0a94f9d57be162987a7e5162b4471809af2ee0897e97cc24187077fb58804380-primary.sqlite.bz2 from xcp-ng-updates: [Errno 256] No more mirrors to try.

                                      Perhaps mirrors are still syncing?

                                        @flakpyro Yes, it always takes a little time for the mirrors to synchronize.

                                        I'm getting correct feedback from the main repository (https://updates.xcp-ng.org/) with the correct updates available.

                                          @gduperrey I wonder why now I have to run those commands on my hosts each time for the updates to show:

                                          yum clean all
                                          rm -rf /var/cache/yum
                                          

                                          Not fun
