Updates announcements and testing



  • Hello,
    I tried on small vdi's and my restore and cr problems solved with this update. I start large vdi restore and I will post results when done. Thank you.

    Edit: Iarge vdi restore and cr job (1.3 terrabyte) complete succesfully. Also delta backup jobs still working without error. Thank you again.



  • Thanks for the tests. I have pushed the vhd-tool package to the updates repository now, for everyone.



  • Update candidate: qlogic-netxtreme2 and qlogic-netxtreme2-4.4.0+10-modules

    • target: XCP-ng 7.5 and XCP-ng 7.6
    • reasons for the update: updated driver to fix various issues including kernel oops
    • packages:
      • qlogic-netxtreme2-7.14.49-1.x86_64.rpm
      • qlogic-netxtreme2-4.4.0+10-modules-7.14.49-1.x86_64.rpm
    • description of the changes:
      • an updated driver was needed to fix various regressions in hardware support for NICs using the bnx2x driver, regressions that started with XenServer 7.2.
      • we had a test package available but an official driver disk has been issued upstream, so we'll release this one instead: https://support.citrix.com/article/CTX239113
    • install: yum install --enablerepo='xcp-ng-updates_testing' qlogic-netxtreme2-7.14.49-1.x86_64
    • testing tips: test if you have the required hardware. If you haven't, just test that it installs correctly and nothing unexpected breaks.
    • reboot: not required if you know how to unload (rmmod) and re-load (modprobe) the driver from the command line. Else a reboot will do it for you.

    • testing tips: basic functions of the hypervisor
    • reboot: yes


  • Did a test on 5 physical hosts (from 7.5 to 7.6): everything is working correctly.

    We should probably release this in "prod" for Monday



  • Xen security update released for 7.5 and 7.6RC1.

    The qlogic-netxtreme2 package will stay in updates_testing a bit longer to let people test it.



  • I have now pushed the qlogic-netxtreme2 package to updates for 7.5 and 7.6.

    Update candidate: xcp-emu-manager

    • target: XCP-ng 7.5 and XCP-ng 7.6
    • reasons for the update: fix a VM migration issue that occurs mostly with loaded VMs
    • packages:
      • 7.6: xcp-emu-manager-0.0.6-1.x86_64.rpm
      • 7.5: xcp-emu-manager-0.0.3-1.1.x86_64.rpm
    • description of the changes:
      • Many users reported seemingly random migration failures. Community testing alllowed to find that it was consistently reproducible by forcing high resource usage such as with this command: stress --cpu 1
      • The problem was caused by the fact that xcp-emu-manager, our replacement of the proprietary emu-manager component from Citrix that handles suspend, resume and migrate operations, did not know how to handle progress messages that arrived when not expected anymore, near the end of the migration process. The fix consists in ignoring those messages when the next step of the process has already started.
      • Fixes https://github.com/xcp-ng/xcp/issues/72
    • install: yum install --enablerepo='xcp-ng-updates_testing' xcp-emu-manager
    • testing tips: migrate VMs, especially loaded ones. Or artificially stress linux VMs with the stress command then migrate them.
    • reboot: no reboot required, no toolstack restart.

    For this specific update, please report your results there: https://xcp-ng.org/forum/topic/522/unable-to-migrate-live-vms-after-upgrading-from-xcp-ng-7-4-to-7-5



  • The update for 7.6 has been made available as a regular update, as xcp-emu-manager-0.0.6-2.x86_64.rpm. It should prevent most migration crashes, but can still get stuck when the VM is heavily loaded. Instead of failing directly, it will now try to wait for a low enough activity to resume the process. We're still working on it to bring a better, complete solution.
