        There's a misunderdstanding when I ask for tests. What hardware you have doesn't really matter. Even if you don't have Intel CPUs, your hosts will receive the updates. So they are impacted. If there are regressions in the updates, you'll be impacted.

        That's why what's the most important with all the updates I ask feedback for is not what they fix, it's what they don't break. A large number of "I installed them, things seem to still function normally" is what we really need.

        Testing the actual changes the updates bring is a plus, but not a requirement to be able to contribute.

          Security Updates released. Intel hardware again. You'll need to choose between safety and performance regarding one of the flaws if you are running untrusted guests. https://xcp-ng.org/blog/2019/11/18/security-updates-for-intel-hardware/

            I just pushed a bugfix update for XCP-ng 8.0: sm-2.2.3-1.0.3.xcpng8.0.

            If fixes a never-ending coalesce issues described at https://github.com/xcp-ng/xcp/issues/298 and https://bugs.xenserver.org/browse/XSO-966

            If you had alread applied all the security updates, there's no hurry. You can wait for the next batch of security updates if you don't strictly require the fix. If you apply it alone, no reboot is required. xe-toolstack-restart is enough.

            closed XCP-ng 8.0 / CH 8.0 coalesce issues #298

              @stormi Thank you!
              I'll be applying and validating the patch.

                @stormi the update actually solves the problem of zombies process, but the coalesce, all disks after backup/snapshot (removal) still continue with a 1 disk stuck in the leaf chain.

                I am also testing the update made available in https://support.citrix.com/article/CTX265619 in an XS 7.1 pool.

                  I'm interested in the results because it's the same patch!

                    @stormi The perception I have is as follows in XCP8:

                    • After backup, all the disks were left with 1 disk frozen in the leaf tree.
                    • Even pausing the VM and rescanning disk, the coalesce process does not start.

                    For CH7.1 with the XS71ECU2020 update, the coalesce process completed 100% by pausing the VMs. We will now re-back it up and see if the coalesce runs again 100%.

                    I used standard times in LIVE_LEAF_COALESCE_TIMEOUT=10.
                    The new test will be with LIVE_LEAF_COALESCE_TIMEOUT=300.

                      @stormi The strange thing is, I had to turn off the VMs, rescan disk and then turn on again.

                      The coalesce process began with the linked VMs (in production) and successfully completed. The following values have been changed at /opt/xensource/sm/cleanup.py :

                      LIVE_LEAF_COALESCE_MAX_SIZE = 1024 * 1024 * 1024 # bytes
                      LIVE_LEAF_COALESCE_TIMEOUT = 300 # seconds
                      

                      Well, apparently everything ok... we will see in our next backup if it will be necessary to turn off the VMs for the coalesce to start and complete correctly.

                        @stormi After the informed change, the backup occurred with 100% success, on no disk in the coalesce chain.

                        We're migrating another cluster to XCP-ng 8!
                        Thanks for the support, quick return and attention.

                          A new update just pushed for XCP-ng 8.0: xcp-ng-xapi-plugins. It adds a plugin that the latest version of Xen Orchestra (just released) needs in order to offer a new feature: integration of netdata for all hosts into a single interface. See the blog post.

                          If xcp-ng-xapi-plugins is the only update available for your hosts, then no need to reboot after installing. A toolstack restart is enough.

                          If you don't need the new feature, you can skip this update until the next batch.

                            New security update candidate for testing in XCP-ng 8.0 and 7.6.

                            Fixes security issues in Xen. Also provides updated microcode for some Intel

                            Details and discussion on https://github.com/xcp-ng/xcp/issues/319

                            Please test (we simply need people to install them and check that they do not see obvious regressions).

                                    Hi

                                    I've a problem with freezing Windows VMs after applaying latest updates - do You know anything about it? Those vms have guest tools from citrix.

                                      I haven't heard of it until now.

                                        @akurzawa I also experienced an issue after the update as well. After the host rebooted and I tried turning on a Windows 10 VM it hung on the Windows boot screen.

                                        • I eventually force rebooted

                                        • Force shutdown + Change CPU and RAM (not sure if the resource adjustments helped of not)

                                        • Start VM and it came up in Windows recovery mode

                                        In the windows recovery mode I just exited and it continued the boot process. This time it booted successfully but I was greeted with the below message upon login.
                                        6c585cde-511c-453e-85e7-ebc9b4156ad3-image.png

                                        I had to use XCP-ng center to use keyboard shortcuts to select yes on the dialog box as mouse input was not working. After the restart everything is working as usual again.

                                        I also have the Windows Updates based guest tools enabled on this VM.

                                        @stormi I think this has to do with the new version of guest tools Citrix has pushed from their release of CH8.1. Checking the services they now show major version 9. Not sure if @akurzawa is facing the exact same issue or a variant of it?

                                          This smells like windows pv drivers upgrades. Had similiar effects on various VMs.

                                            FYI: https://support.citrix.com/article/CTX235404

                                            "Important: Updating to this version of the driver removes the quiesced snapshots capability of the VM. If you are using quiesced snapshots and wish to retain this functionality, do not adopt these 9.0.0.x drivers."

                                            They do not tell about crashing VMs though 🙂
