Working well for me so far. -
So, Citrix published a new kernel hotfix yesterday, so I synced our kernel package to it. As a result, there's a new
kernelpackage in the testing repository, so please update again if you had updated already
yum clean metadata --enablerepo=xcp-ng-testing yum update kernel --enablerepo=xcp-ng-testingAnyone else, just follow the instructions of the big post above, you'll get the new kernel with the other updates.
I'll update the big post with details about the new kernel update.
-
@stormi installed this new kernel as well and rebooted.
Still no regression issues found till now. -
@stormi All new patches applied fine. No apparent problems identified so far.
-
@stormi So far, so good for my systems with the re-updated kernel.
-
A big thank you to those who tested, and last call for the others! Publish time is close.

If you are wondering "how close", I delayed them a bit to potentially group them with another update.

Hi @stormi
Any idea how long "a bit" is?
Cheers!

The updates I wanted to group them with did not come, so it all got delayed (and retrospectively I could have released them earlier).
Are you waiting for a specific fix?

Not specifically, but we have not yet installed the previous patches. We were planning on combining them with the upcoming patches. Since it always takes a while to update / reboot all hypervisors we wanted to avoid double work if we were to install the current available updates today and for example tomorrow new ones are released
-
The best I can say is: real close... probably...
-
The long awaiting (and awaited?) train of updates was finally published (including the XAPI update)!

A big thanks for your feedback everyone, and get ready for the next ones!

We don't see them yet, but I assume it may take a few hours for the mirrors to update?

In theory, mirrorbits should always redirect you to a mirror that has the latest files you are requesting. However there's also a local cache for yum metadata. Try to clean it:
yum clean all. -

yum clean all.Ah yes, after that I see 22 packages. Just googling for this but appears to be based on the
metadata_expireoption in/etc/yum.conf. The man page says the default is 6 hours, but that config file has a commented out90m. Either way, I'll wait a few hours/until tomorrow and then it should show all packages to update in XOA on all servers -
New security updates (xen, kernel)
Citrix security bulletin: https://support.citrix.com/article/CTX335432
Impact: privileged code in a guest VM may crash a host or make it unresponsive.
Note: although PV guests are unsupported since XCP-ng 8.1, this very update actually breaks PV 32 bit compatibility (on purpose, for a performance gain on dom0).
However, you really should not have any remaining PV guest at this stage (especially 32 bit), for security reasons. There are unfixed vulnerabilities, and they won't be fixed.🦺 Our support will be ready to help migrate to HVM (better), or other solutions.
Test on XCP-ng 8.2
yum clean metadata --enablerepo=xcp-ng-testing yum update kernel linux-firmware xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools --enablerepo=xcp-ng-testing rebootVersions:
- xen-*: 4.13.4-9.18.1.xcpng8.2
- kernel: 4.19.19-7.0.14.1.xcpng8.2
- linux-firmware: linux-firmware-20190314-2.xcpng8.2
What to test
Normal use and anything else you want test. The closer to your actual use of XCP-ng, the better.
Test window before official release of the updates
~2 days. I plan to release the updates on Monday morning, CET.

@stormi Updated my two host playlab and tested Debian 11 and Windows 10 VMs (create, live migrate with guest tools, start/stop/reboot, online-/offline storage migration from/to shared and local SR, snapshot with/-out RAM and revert) and imported an Ubuntu VM for testing as well. All seems to be good.
Made some full copies of the Debian VM while at it to see what performance I get in my temporary 10G setup with a simultaneous live migration between hosts, which worked out nicely (knowing that this is not a realworld test and just for fun).
-
We should expect some perf bump in dom0, around 5 to 10% which is nice
(thanks to PV32 removal) -
Tested on my HPE ProLiant DL385 Gen10 (EPYC), everything is working too
-
You mean xen 4.13.4, right? That's what's I installed.
I updated a few active machines and no problems so far:
HP G5 (E5450), HP G8 (E5-2680), AMD (Opt 6380)
