    This release batch contains fixes, and a security fix on an optional package,

    • kexec-tools: Update to sync with Xen Server:
      • Add checks to reboot a crashed host if kernel crash handling doesn't complete.

    Control Plane

    As this is my first time installing these update candidates,

    Actually we moved first batch of packages that landed in testing to candidates repo, to avoid mix up in the second batch that just landed in testing repo. Since nothing new appeared in candidate you should probably already had them before, home this is clarifying what is actually happening 🙂

    Next yum update should just pull the latest stable versions?

    Not if you already have installed then from testing (or candidate) repo, because versions are same, it's only the distribution channel that change, no impact for testers.

    I'm not sure what you understood from @scarfantennae's question, but that we moved packages from xcp-ng-testing to xcp-ng-candidates doesn't seem on topic here.

    The question is: "now that I've applied this update candidates from the testing repositories, am I definitively in testing mode?".

    The answer is: no, because:

    • The --enable-repo switch only applies to the two commands you ran: clearing the cache and applying updates. The repositories remain disabled by default, so yes, next time you update you'll only get stable updates if there are any.
    • Either the exact packages that you installed will be pushed as official updates (in which case there will be nothing for you to do), or we'll push newer updates that will supersede them automatically next time you update.

    Hope it's clear.

    XOSTOR users: specific update procedure

    Some XOSTOR packages are provided in separate repository, and should be installed along xcp-ng regular packages, using the following commands:

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

    Note: linstor packages themselves have not been updated, only kmod-drbd and xcp-ng-release-linstor. Thus, this time it's not necessary to restart the satellites before rebooting.

    The following XOSTOR-specific package received updates (and must be updated in the same transaction, which the above update commands will do):

    • xcp-ng-release-linstor: 1.4-2.xcpng8.3 -> 1.5-1.xcpng8.3 (from xcp-ng-testing repo)
    • kmod-drbd: 9.2.16-1.0.xcpng8.3 -> 9.2.18-2.0.xcpng8.3 (from xcp-ng-linstor-testing repo)

    Test on XCP-ng 8.3

    Warning: XOSTOR users should skip this part and follow the instructions of the previous section.

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

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

    What to test

    As usual, normal use and anything else you want to test.

    Test window before official release of the updates

    ~2 days

    We would like to thank users who reported feedback since our last call for testing:

    Since it's a lowest priority you can take all the time you need, and If too busy, no problem we can do it for you and then backport the change to XCP-ng.

    Or Is there any volunteer interested to learn about how to contribute to xcp-ng ? I can mentor you, pm me.

    New security update candidates for XCP-ng 8.3 LTS (kernel)

    Test window before official release of the updates

    ~3 days

    The testing window is extended a bit, expect also a next batch (to be tested later this month).

    It has been planned to group updates for the convenience of administrators (stay tuned in blog).

    Meanwhile If you didn't notice yet, an updated xen-4.17.6-9.2.xcpng8.3 package landed in testing repo, it addresses some low risk vulnerabilities as reported at:

    More to come soon
