XCP-ng 8.3 updates announcements and testing

@rzr Installed on my 2 node lab pool, so far no issues.

HP DL G8 Intel E5-2673 v2 shows 64 CPUs. The actual CPUs show correctly, the higher ones (that don't exist) show [CPUxx] Unable to fetch temperature (19 - No such device)

Machines with hotpluggable CPUs are a pretty tricky case, the logic tries up to "maximum possible CPU" and fails here because the CPU is not online (No such device error). That doesn't prevent the temperature from getting fetched for CPU that exists.
I can try to add a check to hide this specific error, so it's doesn't create noise for offline CPUs on such machines.

Temps seem to be working on i5-10500T:

[11:46 delta-2 ~]# xenpm get-core-temp
Package0: 57°C
CPU0: 56°C
CPU2: 57°C
CPU4: 56°C
CPU6: 56°C
CPU8: 55°C
CPU10: 57°C

As this is my first time installing these update candidates, is there no other action required after doing:

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

Meaning I am not permanently in testing mode now? Next yum update should just pull the latest stable versions?

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.

Updated my four host home lab pool with latest batch of updates with no observed issues.

@rzr We've found a regression in the VM revert with the new version of xapi (26.1.11)

The CD VBDs of the pre-revert are not removed when reverting, this means that the reverted VM usually ends up with duplicated VBDs for CDs.

We've verified a fix for it and we're integrating it as soon as possible. This means that this test cycle will take longer.

@rzr @stormi Perfect, thanks for clarifying!

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

What to test

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