XCP-ng 8.3 betas and RCs feedback 🚀

XCP-ng-JustGreat

Upgraded 3-node pool (home lab: Dell OptiPlex 7040 SFF x 3) from 8.3 RC1 to 8.3 RC2 using bootable ISO. It worked perfectly for me. As others have noted, it does ask you to select the management interface when upgrading the slave nodes. Once you do that, it automatically populates all of the previously configured network parameters for that host so you are really only confirming the existing values. The OptiPlex 7040's (i7-6700) all have Intel VPro AMT so they are running headless. The MeshCommander program is used to access the VPro console on each host. A DisplayPort display emulator dongle is needed to keep the integrated-GPU active in order to be able to see the console and firmware setup screens with this configuration. It's effectively a poor man's iDRAC. So far, everything is working well on 8.3 RC2.

A week or two ago a bunch of updates went out. Were these part of RC2? I updated via yum back then and since this announcement nothing new has come up.

Is there a command line command to run to verify what is installed now is RC2?

jivanpal

@archw Yes, if you installed any 8.3 beta or RC and have recently performed a yum update and reboot, then you are up to date with the packages that are included in the 8.3-rc2 release.

I decided to try upgrading my master to 8.3 in BIOS mode (see yesterday's post about UEFI failure). The upgrade seems to have gone well overall but when I try to access my NFS-mounted SRs I get

"SR_BACKEND_FAILURE_140(, Incorrect DNS name, unable to resolve., "

Evidently not everything was preserved in the upgrade.

@nomad A host is not supposed to lose its DNS configuration upon upgrade, but it looks like it did. Can you check from the CLI?

nomad

@stormi It was user error.

/etc/hosts wasn't preserved and the storage NAS isn't in DNS.

Looks like this RPM isn't available in 8.3 yet. Please remember to make it available as we need it.

It was created for Ticket#7714169

thanks!

stormi

@nomad @ronan-a is on it. It's built but not made available in the base repository yet.

Upgrade to RC2 worked fine so far with netinstall ISO in ventoy on a 8 gen i5 HP laptop. And a "full" ISO on its own USB on a Lenovo Thinkcentre Ryzen 5 2400GE

2 days ago I upgraded my fully patched Ryzen 5 RC1 to RC2 by ISO.
Unfortunately I also upgraded my XO to commit aa490.
All backup jobs since then has triggered CPU performance alerts on my backed up delta, offline VM, XCP-ng host and the VM running XO.
I will update the XO to latest commit today.
Are there any changes in RC2 that could cause this?
I have only received 1 alert on high memory earlier.

ISO update (as recommended) for my pool of three XCP-ng 8.3 RC1 hypervisors.
Everything went perfectly for each server.
I had to reinstall the additional packages (traceroute vim-enhanced mtr etc...), re-enable LLDP advertisements on the network interfaces (lldptool -L -i eth0 adminStatus=rxtx) and recreate the multipath configuration file (/etc/multipath/conf.d/huawei.conf).
In short, nothing seems abnormal.

can't install zabbix on 8.3.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

at 8.2 i only need to enable more repos, but 8.3 already use it own Vates mirror for Centos.

yum install pcre2 --enablerepo=epel,base,sources

Loaded plugins: fastestmirror

@ph7 I don't see much changes which may lead to this result at first sight.

It is indeed missing. I must have missed something when I replicated the repository from CentOS vault.

Ok, I'm feeling dumb. I just mounted the guest tools ISO (hosts -> hostname -> console -> "select disk(s)" pulldown, select "guest-tools.iso") and I'm seeing kinda old versions of xe-guest-utilities (-2 instead of -12).

: || lvd@vm42 ~ [1023] ; ls -l /media/Linux/xe-guest-utilities*rpm
-r--r--r--. 1 root root 985556 Dec 11 2023 /media/Linux/xe-guest-utilities-7.30.0-2.i386.rpm
-r--r--r--. 1 root root 985384 Dec 11 2023 /media/Linux/xe-guest-utilities-7.30.0-2.legacy.i386.rpm
-r--r--r--. 1 root root 1246820 Dec 11 2023 /media/Linux/xe-guest-utilities-7.30.0-2.legacy.x86_64.rpm
-r--r--r--. 1 root root 1247000 Dec 11 2023 /media/Linux/xe-guest-utilities-7.30.0-2.x86_64.rpm

When I do the same on my production 8.2.1 pool I see

: || lvd@chipmunkdev ~ [1000] ; ls -l /media/Linux/xe-guest-utilities*rpm
-r--r--r--. 1 root root 985488 Feb 7 2024 /media/Linux/xe-guest-utilities-7.30.0-12.i386.rpm
-r--r--r--. 1 root root 985308 Feb 7 2024 /media/Linux/xe-guest-utilities-7.30.0-12.legacy.i386.rpm

-r--r--r--. 1 root root 1246948 Feb 7 2024 /media/Linux/xe-guest-utilities-7.30.0-12.x86_64.rpm

Should I be looking somewhere else for the most recent xe-guest-utilities?

Same alert today with commit 63a88
Should I report this in Home / Xen Orchestra / Backup ?

stormi

@ph7 If you can test with an older version of XO and see if the issue is still present, this might help understanding whether it's an XO issue or not. But I think you can also already create a dedicated topic where XO devs can tell if they see what this could be.

stormi

@nomad Good point!

So, they are the same tools (8.2 got the update later, based on that of 8.3), but the version is defined in a peculiar way (based on the release of the RPM, which I mistakingly re-initialized to 1 on XCP-ng 8.3). I'll fix this, but you can already use them if you need them.

nomad

@stormi If it's the exact same thing just with a different version number I can wait for a future update. I already have the -12 RPM in my yum repo for automatic install on all VMs.

I was looking to see if there was any notable changes from what we already had as well to see if an icon for AlmaLinux would show up in the home -> VMs list (everything else has an icon showing the OS running on the VM, just poor Alma is left all alone at the display ball.)

stormi

@nomad There are two key players in this icon thing: the guest tools who report the OS name (this already works), and then Xen Orchestra matching this to an icon. In Xen Orchestra 5, the icon set is not easy to expand, so the developers said this would be done in XO 6.

nomad

@stormi I'm glad to know I was slightly right about some of the way it works anyway.
