XCP-ng 8.3 updates announcements and testing

[Andrew]

@gduperrey I updated my little AMD Ryzen 5 5600U (Zen3) and it's running great!

As for the important VM to VM network performance, using Debian 13 and iperf3 single thread, before (update not enabled) is about 7.2-8Gb/sec. After the update (xen-platform-pci-bar-uc=false) I get about 10.1-13Gb/sec. So that's about a 40-60% improvement. This brings it in line with similar small Intel systems.

I did not see any change (or problem) setting it on my small test Intel system (getting about 10.1-10.8Gb/sec).

FYI: Remember, after the config change and xe-toolstack-restart, restart the VMs!

Yeah I had to stop then start the VM to enjoy the new performance. On my end, iperf (not iperf3) bring even more perf on my setup, especially with multiple threads (-P4 and -P8 gave more than 100% boost)

New update candidate for you to test!

A new non-urgent update is ready for user testing before a future collective release. Below are the details.

A bug was found in the Emergency Network Reset due to desynchronisation between xsconsole and XAPI. This issue prevented the Emergency Network Reset from working at all. This update includes the fixes from the upstream xsconsole project to fix it.

---

Maintenance updates

• xsconsole
  • Backport sync of network reset trigger file path with XAPI to fix emergency network reset
  • Backport fix for pool.conf IPv6 to avoid IPv6 truncation

Test on XCP-ng 8.3

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

Reboot is not strictly necessary, but the xsconsole instance running on the first virtual terminal of your host won't be restarted otherwise. If you do not reboot, make sure to start xsconsole from another terminal after the update.

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

Versions:

• xsconsole: 11.0.8-1.2.xcpng8.3

What to test

Normal xsconsole usage, is still useful feedback. However, if possible, the most helpful test would be performing an Emergency Network Reset through xsconsole, making actual configuration changes and verifying that they are correctly applied after reboot.

Test window before official release of the updates

None defined, but early feedback is always better than late feedback, which is in turn better than no feedback
