Thanks @gskger for the feedback. The update has been pushed on Wednesday evening and the blog post published yesterday: https://xcp-ng.org/blog/2020/11/26/security-and-bugfix-update-cve/
For XCP-ng 8.2, updates also include UEFI support fixes.
-
@stormi thank you as well for regulary pushing out security updates and bugfixes
. Makes me feel comfortable to have a solid virtualization environment (even with a non-commercial homelab) 
. -
Thank you for the feedback also
Ideally, we'd like to have more people like you! -
A reminder about this thread and what it's for.
This is where we announce new update candidates for stable releases of XCP-ng, so that you can provide feedback before we push them to the updates repositories for everyone.
For security-related updates, we usually need quick feedback.
Anyone can test. Just:
- Subscribe to this thread (and make sure to enable mail notifications in your forum settings)
- Install the update candidates when we announce one (we usually provide the installation instructions)
- Check that you don't spot any obvious regression. We're not asking that you do extensive QA of the updates for us, just that you can confirm that it works for you.
See you in the next few days for a new batch of security updates

New security updates candidates
Update candidates are ready for XCP-ng 8.1 and 8.2.
Install them with:
yum clean all --enablerepo=xcp-ng-testing yum update kernel xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools xenopsd xenopsd-cli xenopsd-xc --enablerepo=xcp-ng-testingAnd reboot.
Please install them and report to confirm that everything is still working as expected. -
Update done, rebooting went well, will start to monitor for anomalities.

@stormi Same here. Updated my three host playlab (8.2.0 fully patched) with no problem. Starting, stopping, migrating (running/stopped) VMs, storage migration (local, shared SR), creating/snapshoting/deleting VMs (Linux only) worked as well as backup and restore (of one VM). Looks good.
-
@stormi I've updated my R620 running XCP-ng 8.2, and only issue I've observed thus far is the network slowdown that we've been discussing elsewhere.
I need to rebuild the kernel again without the one patch. Has there been any feedback / response from the Xen group?
-
@danp I haven't contacted them globally though I asked a developer individually for guidance on how to move on. My issue is: we do know that for some users there's a performance impact and it's related to the kernel updates, but the results of the tests don't reveal yet the exact updates or patches that are involved, or not for everyone (though the one you found looks definitely a good candidate to explain at least parts of the slowdown). And I want to see where @fohdeesha's attempt at helping everyone get better perfs will lead.
(but let's continue on the dedicated thread)
-
Thanks for all the tests. The security updates have been pushed: https://xcp-ng.org/blog/2020/12/18/december-2020-security-updates/
-
New security update for XCP-ng 8.2 only
See https://xcp-ng.org/forum/post/35658
The interesting story about this one is that it was first reported and debugged on this forum, on the thread linked just above, without us knowing that it would be identified as a security (DoS) issue by Xen developers when we'd report it to them.
Please install it, reboot, and as usual check for any obvious regressions.
-
@stormi Can not speak for the issue solved, but upgrading my three host playlab from XCP-ng 8.2 fully patched worked as well as create, live / storage migrate, copy, delete, snapshot (with/without ram), backup and restore of Linux and Windows 10 VMs. Nice upstream, downstream and forum work
. -
@gskger Thanks, you're always there for the tests!
-
Indeed, that's really useful! Thanks @gskger
-
Update pushed to the update repository, blog post to be published on Monday.
-
Another update in testing:
ca-certificates, for both XCP-ng 8.1 and 8.2.The one we have (from Citrix Hypervisor) is 2 years old and it's good to refresh the list of root certificates from time to time. Not much impact on XCP-ng actually because it's mostly used when you wget or curl an external URL AFAIK. And probably for yum too.
Install with
yum clean metadata --enablerepo=xcp-ng-testing yum update ca-certificates --enablerepo=xcp-ng-testingThen usual checks that nothing looks unexpectedly broken.
-
@stormi
I did not test the updates in the test-repository this time because I wanted to test the Rolling Pool Update function from XO. I recently created a pool of 2 hosts.I noticed the patches were available according to XO on the recently installed host, but not on the host I am using already for a longer time (and used to install the test-patches before). This host is also the pool master.
Only after ayum clean alland ayum updatethe updates were visible on the first host and thus the pool.After fixing that, the Rolling Pool Update went very smooth. I like this feature!

@stormi said in Updates announcements and testing:
yum clean metadata --enablerepo=xcp-ng-testing
yum update ca-certificatesAfter the rolling pool update of the released production patches, I wanted to test the ca-certificates from the testing repository as well.
