        New update candidates are available to fix the recently disclosed Xen security issues (see http://xenbits.xen.org/xsa/ and https://support.citrix.com/article/CTX246572).

        Please test as soon as possible. Objective of the test: make sure that there is no obvious regression. Just tell us that you installed the update candidate, the version of XCP-ng, and whether it works as well as before or not after a reboot.

        XCP-ng 7.6

        xen-4.7.6-6.4.1.xcpng

        Installation of the update candidate:

        yum install --enablerepo='xcp-ng-updates_testing' xen-dom0-libs xen-hypervisor xen-tools xen-dom0-tools xen-libs
        

        Reboot required after the installation.

        XCP-ng 7.5

        xen-4.7.5-5.8.1.xcp

        Installation of the update candidate:

        yum install --enablerepo='xcp-ng-updates_testing' xen-dom0-libs xen-hypervisor xen-tools xen-dom0-tools xen-libs
        

        Reboot required after the installation.

          Anyone? This update candidate should be as safe as could be and internal tests are OK, but I don't want to push it before I get feedback from a few testers.

              security fix installed. Does it require a reboot of the system?

                  @stormi testhost updated, restored some part of our infrastructur (DC, Mail, ...) on local ZFS pool, connected the VMs to a test network. Runs. A bit slow (more vCPU used than the PCPU can delivier), but runs.

                    @stormi said in Updates announcements and testing:

                    Anyone?

                    I updated one host in a pool and reboot. It is working as before. Seems no problem. I can't see any diffrence vcpu usage as @borzel say.

                      So far so good .. I haven't noticed any visible change in performance like @borzel but still monitoring.

                        Since there's an update for both XCP-ng 7.5 and 7.6, please all tell me which version you tested 🙂

                          @AllooTikeeChaat there was no performance change, was the first use of that test host 🙂

                          @stormi XCP-ng 7.6, just HVM, no PV

                            If all goes well I'll push the updates to everyone on monday. Meanwhile, please go on with the testing if you can.

                                Thanks to everyone who tested the update candidate. I've now pushed the security update for XCP-ng 7.6. I'm holding that of XCP-ng 7.5 until at least one person confirms that it's working for them.

                                    I've installed the updates on a pool. Now every time I migrate a pfSense HVM VM within the pool the console is gone and memory usage is at 100%. I did do the following on the pool master: yum update xenopsd xenopsd-xc xenopsd-xenlight --enablerepo='xcp-ng-updates_testing'. The package version also differs from other hosts (0.66.0-1.1.xcpng versus 0.66.0-1.el7.centos). Would that be the cause?

                                      @Ultra2D Could you downgrade to the previous version with yum downgrade xenopsd xenopsd-xc xenopsd-xenlight, restart the toolstack and tell us if migration works better?

                                      Also make sure that you already have the latest updates for xcp-emu-manager, which fixed many migration issues about two months ago. See https://github.com/xcp-ng/xcp/wiki/Updates-Howto#a-special-word-about-xcp-ng-75-76-and-live-migrations.

                                        @Ultra2D In fact, you may be right, differing versions of those packages may cause an issue, because both hosts may behave differently regarding VMs that have no platform:device-id set.

                                        So another test to do would be install the update candidate for those packages on all hosts and restart their toolstack, then test migration of that VM again.

                                          @stormi Thanks. Installing the update candidate on all hosts and restarting the toolstack works, but only after power cycling the VM once.
                                          xcp-emu-manager is version 0.0.9-1

                                          Is it advisable to stay on the testing repo until the next version? There are some more non-Windows HVM VM's.

                                            @Ultra2D so you mean that installing the updated packages would "break" the first migration of such a VM unless it's been rebooted once? If that is so, then I'd advise to revert to the previous version (or to make sure not to attempt a migration without power cycling the VMs once). Else, your choice. If the updated packages bring a benefit to you, you can keep them, else revert to the previous ones.
