Updates announcements and testing



  • @stormi Is it safe to assume that these packages are only intended for the latest version of XCP-ng?


  • XCP-ng Team

    @danp yes, the latest stable version of XCP-ng, so 7.5 at the moment.

    I updated my message to add the target version.



  • In a pool environment, does this package need to be installed on the master only, or on all the nodes?


  • XCP-ng Team

    @lavamind All nodes in the end. But maybe installing it only on one node to do a test would be OK, provided that's the node where the delta backup restore operation occurs. It will not make the node incompatible with the others. But if the operation involves several nodes, better upgrade them all. Maybe someone else (@olivierlambert ?) can give more information about that.


  • Admin

    It's better to update on all nodes, because you won't have to remember which one is patched or not. The risk is very low, we aren't expecting any side effect.



  • 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.


  • XCP-ng Team

    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.

    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


  • XCP-ng Team

    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.


  • XCP-ng Team

    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


  • XCP-ng Team

    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.

    An update to XCP-ng 7.6 has been pushed: xcp-emu-manager-0.0.9-1, that fixes all known migration issues (well, except this bug from XenServer: https://github.com/xcp-ng/xcp/issues/111). Update for XCP-ng 7.5 is being prepared.


  • XCP-ng Team

    Updates to XCP-ng 7.6 have been pushed today:

    Reminder: how to update.

  • XCP-ng Team

    New update candidate for XCP-ng 7.6. It adds support for NFS 4.1, that has been contributed by a member of the community and already merged upstream in the XAPI project!

    Install it:
    yum update sm sm-rawhba --enablerepo='xcp-ng-updates_testing'

    Revert:
    yum downgrade sm sm-rawhba

    Thanks in advance for your feeback!
