      @bleader @stormi Microcode was updated and initrd was rebuilt correctly and the system rebooted with the updates, so I don't know what the error was. Running the commands manually produces no errors. Maybe the system was busy and it was the shorter 30 second settle timeout (vs. the default 120 seconds), at this time it returns quickly.

      The warning was only on one system (out of 5 identical pool hosts) but caused no actual issues.

          New update candidates for you to test!

          As you may know, we group non-urgent updates together for a collective release, in order not to cause unnecessary maintenance for our users.

          The moment to release such a batch has come, so here they are, ready for user tests before the final release.

          • XAPI:
            • Synced with XS82ECU1074
              • Enhancement: robustification of the command xe host-emergency-ha-disable
              • Correction of different issues:
                • Performing a hard shutdown of a VM may hang due to unnecessary RBCA permission checks. An icon (yellow triangle) may then be displayed on some management applications, indicating that the shutdown process did not complete successfully.
                • Canceling a hard shutdown of a hung VM fails because the cancel function only checks for proper shutdowns.
                • Migrating VMs from 8.2.1 to 8.3 with the xe vm-migrate command may fail with the error 'Failure: Unknown tag/contents'.
                • You may encounter a 500 error (internal server error) when trying to retrieve RRD measurements from a powered off virtual machine.
          • xsconsole:
            • Synced with XS82ECU1074: Fix for a time-out when creating an iSCSI SR.
          • guest-templates-json:
            • Add generic templates for Linux BIOS and UEFI
            • Synced with XS82ECU1085:
              • Oracle 8 requires minimum 2 vCPUS.
              • Added template for Ubuntu 24.04
          • sm:
            • Synced with XS82ECU1075
              • Updated multipath.conf for several SANs
              • Fix for CA-393194: Find the real PV in a VG before removing the VG.
          • blktap: Synced with XS82ECU1075: Improvements on coalesce performance.
          • curl: Backport fixes for several CVE: CVE-2024-2004, CVE-2024-2379, CVE-2024-2398, CVE-2024-2466, CVE-2024-6197, CVE-2024-7264

          • xenserver-status-report: Update to latest version, synced with XS82ECU1058
          • python-defusedxml: Added as a new dependency of xenserver-status-report.
          • Alternate Drivers: Updated to newer versions.
            • intel-i40e-alt: From version 2.22.20-3.1 to 2.22.20-5.1
            • mellanox-mlnxen-alt: From version 5.9.0.5.5.0-1.1 to 5.9.0.5.5.0-1.2

                    New security update candidates for XCP-ng 8.2 LTS (xen, microcode_ctl)

                    Two new XSAs were published on November 12th 2024.
                    Intel published a microcode update on the November 12th 2024.

                    NOTE: This was published soon after the previous testing updates, therefore, we did not publish the previous and everything will be published altogether.

                    • XSA-463 an unprivileged guest making two quick accesses to the VGA memory can deadlock a host.
                    • XSA-464 an unprivileged PVH guest may access sensitive information from the host, control domain or other guests.

                    SECURITY UPDATES

                    • xen-*:
                      • Fix XSA-463 - Deadlock in x86 HVM standard VGA handling. A mistake in the locking of process of the "standard" VGA memory makes it possible for a guest to make 2 quick accesses and create a deadlock that will hang the host.
                      • Fix XSA-464 - libxl leaks data to PVH guests via ACPI tables. The ACPI tables for PVH guests initialization left the excess memory space with its previous content, which was then copied to the guest memory as it was, resulting in possible leak of sensitive information. This doesn't affect XCP-ng in its normal configuration, as only HVM and PV-in-PVH (not affected) guests are supported.
                    • microcode_ctl:
                      • Latest Intel microcode update, published on November the 12th:
                        • Security updates for INTEL-SA-01101
                        • Security updates for INTEL-SA-01079
                        • Updated security updates for INTEL-SA-01097
                        • Updated security updates for INTEL-SA-01103
                        • Multiple other updates for functional issues.

                    Test on XCP-ng 8.2

                    Install all the current update candidates: the ones we already made users test to prepare for the next train of updates, and the new ones which fix security vulnerabilities. We will release them all together.

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

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

                    Versions:

                    Security updates:

                    • xen: 4.13.5-9.45.1.xcpng8.2
                    • microcode_ctl: 2.1-26.xs29.6.xcpng8.2

                    The rest of the packages is described in the previous update candidate announcement.

                    What to test

                    Normal use and anything else you want to test.

                    Test window before official release of the update

                    ~ 2 days because of security updates.

                      We also need you to test updates for XCP-ng 8.3. I created a new thread dedicated to XCP-ng 8.3, and renamed this present thread to make it dedicated to XCP-ng 8.2.

                      Please ensure you follow the new thread if you plan to help on testing XCP-ng 8.3.

                      New thread: https://xcp-ng.org/forum/topic/9964/xcp-ng-8-3-updates-announcements-and-testing
