XCP-ng 8.3 betas and RCs feedback 🚀

ThierryC01

Everyone: we are about to release XCP-ng 8.3 Beta 2!

It was delayed by one month due to the UEFI issues discussed above, now fixed.

The last thing we need is your feedback on the updated installation ISO: https://updates.xcp-ng.org/tmp/xcp-ng-8.3.0-beta2-test3.iso

I hope I have more success than with the test2 ISO for which I don't remember getting any feedback

Hi,

I have updated my xcp-ng 8.3 beta 1 with this xcp-ng-8.3.0-beta2-test3.iso and while it boots, I have lost all my VMs and no SR are recognized, I am left with a just a server that sits on its own and I cannot connect an oldest XOA to it. If you need more info (logs, anything) tell me now as I really need my VMs back, I think I should be able to revert to the previous version if the backup worked. I only have one homelab server so this is the situation where you kind of update your live prod...

Before upgrading, I applied all the 8.3 patches that were pushed recently.

@stormi It was the time. It was not just a bit off, it was 12 years off

Should have thought of that, we had similar issues at work with Rocky 8 servers. I naively thought the NTP servers would have prevented such issues, but I am not sure the NIC works at install time. I have never been able to get the netinstall to work off that box. Meh... this worked, thanks you very much!

@ThierryC01 Oh, I didn't think someone would upgrade from Beta1 using the ISO. Actually the test4 ISO forbids it to avoid upgrade issues.

Can you share the /var/log/installer/install-log file? (on a separate thread, where you can ping me)

ThierryC01

@stormi Thanks for your help, my VMs are back online but there is no more stats in the tab "stats" for any VM and the host, the log page gives this error multiple times:

vm.stats
{
  "id": "3c807c46-bfdc-f33a-5954-4de92bcf3f08",
  "granularity": "seconds"
}
{
  "message": "Unable to get the true granularity: 5",
  "name": "FaultyGranularity",
  "stack": "FaultyGranularity: Unable to get the true granularity: 5

}

This is an error another user reported through a support ticket. Do others confirm?

olivierlambert

I confirm the issue here

Tristis Oris

same issue.

rmaclachlan

Same here (ticket is in).

Anyone having issues with NFS SR performance too? Since the update my VMs are transferring about 140MB/s vs before the update we were seeing speeds around 440MB/s.

I'm using "dd if=/dev/zero of=tmp bs=1G oflag=dsync count=1" to test, if I SSH onto the host I can get full speed to the NFS mount but from within a VM it is much slower, this means backups are also crawling since XOA can't read the VHD very quickly.

iSCSI performance seems unaffected.

Same issue on latest 8.3 release, no stats.

@stormi
OmniOS guest fails to boot in xcp-ng on version 8.3.

Installation is fine: create a new vm, set viridian=false and installation progress smoothly. I've noticed that installation seem to lack PV-drivers.

When booting from freshly installed disk it panics with:
panic[cpu0]/thread=ffffffffffbc490c0: unable to configure /xpvd nexus

I've tried several version of OmniOS (and latest OpenIndiana), I also tried Solaris 11.4, tried disabling apix with apix_enable=0 in /etc/system and all without success.
The same setup in xcp-ng 8.0 works like a charm with working PV-drivers (but no tools).

Anyone with an idea of a workaround or even better, a resolution to this.

olivierlambert

If you have the same problem in 8.2, then it's not 8.3 related.

BobTB12

@olivierlambert oh, sorry, got too carried away and did not notice this is 8.3 beta.

kait

can confirm the stats/true granulrity issue as well

ph7

No stats :o(
but netdata seems to work

stormi

So we are working on this issue. The format of the JSON output changed, which explains why it doesn't work in XO anymore. We'll fix it either in XCP-ng or in XO, depending on what is the best thing to do.

@stormi
No stats in XO-lite v0.1.7 (0d127) , as you probably already know

stormi

@ph7 Indeed, we know about XO lite too. Thanks

stormi

And XCP-ng 8.3 Beta 2 finally released!

https://xcp-ng.org/blog/2024/02/15/xcp-ng-8-3-beta-2/

Fixes are on the way for the stats issue. It involves both XCP-ng and Xen-Orchestra, so this will take a few more days.

Tristis Oris

Good news. Release at this year possible?
What xapi version now at 8.2.1? dunno how to check it.

@stormi I assume you had issue so took file down as link is giving a 404 page not found? lol
