XCP-ng 8.3 updates announcements and testing

[flakpyro]

@gduperrey Installed on the same 2 hosts as the last batch of test updates released in December.

No issues to report so far, ran a backup job after after without issue.

[olivierlambert]

Works for me!

[gskger]

@gduperrey Installed on some R720s with GPUs and everything works as expected. Looks good

Edit: also installed the update on my playlab hosts and a Dell PowerEdge R730. Again no issues and all hosts and VMs are up again.

Upgraded to testing as I had problem with coalesce on 8.3 and VDI of 330GB. Smaller one coalesced fine (50Gb and 100GB) but on 330G it run for 12sec and said something about timeout error. With testing packages coalesce is working fine.

@gduperrey Updates installed and running but I don't have 8.3 in production yet...

[ph7]

Tested OK on
Intel(R) Core(TM) i7-4710MQ CPU @ 2.50GHz

Update published: https://xcp-ng.org/blog/2025/01/23/january-2025-maintenance-update-for-xcp-ng-8-3/

Thank you for the tests!

@gduperrey On my 2 hosts on the pool I did a yum update on the slave first. Idiot!
It updated and rebooted. Now wanted to do the same on the master. Doesn't show any updates!

How do I install the updates on the master now?

[gduperrey]

@manilx Have you tried cleaning the yum cache on the master?

yum clean metadata

[manilx]

@gduperrey YES! Now the updates show. Updating.....

@gb.123 I doesn't seem directly related to this thread, which is dedicated to testing update candidates. Maybe open a new thread?

[gb.123]

@stormi

Done.
Since this I checked this after a while, I wasn't sure if it was related to update or independent. I have opened the new thread as you suggested in the 'Network' section

New update candidates for you to test!

• intel-microcode:
  • Latest Intel release microcode-20250211:
    • Security updates for: INTEL-SA-01166, INTEL-SA-01213, INTEL-SA-01139, INTEL-SA-01228
    • Updates for multiple functional issues
    • Upstream update drops files for older Sapphire Rapids steppings, we kept the previous versions
• netdata:
  • Update to Netdata v1.47.5

• qemu: Backport a security fixe (CVE-2023-3354) for QEMU VNC server vulnerability
• r8125-module: Disable some performance functionalities in the driver (TXchecksum/SG/TSO) by default to workaround bugs on Windows Server 2022 guests. These can be re-enabled using 'ethtool -K eth0 tx on tso on sg on'
• sm:
  • Fix issue where users may encounter problems with HPE Nimble arrays: unable to mount iSCSI LUNs, non-functional or imperfect multipathing.
  • Regarding Large Block driver, always enable the VG on the emulated device.
  • Prevent corruption in the LINSTOR KV-store caused by a race condition between user calls and GC.
• systemtap: No functional changes. Fix compilation for compatibility with new gcc version.
• xapi: Re-enabled nested virtualization in 8.3, with the same limitations as in 8.2.
• xcp-emu-manager: No functional changes, Fix rpm spec file for new cmake version
• xcp-ng-release: Update cipher list in .curlrc
• xcp-ng-xapi-plugins:
  • Add new service plugin to manage (start, stop, ...) XCP-ng services
  • Add a new ipmitool plugin to get information from ipmitool that:
    • Returns information about sensors
    • Returns ipmi lan information
• xen:
  • Re-enabled nested virtualization in 8.3, with the same limitations as in 8.2.
  • Fix XSA-467 / CVE-2025-1713
• xo-lite: update to version 0.8.0. For more information you can read latests posts on the Xen Orchestra blog: 0.7.1 & 0.8.0.

Regarding the nested virtualization, Xen-Orchestra is not yet updated to allow this in 8.3, even if we see the option in the advanced tab of the VM. They are working on it and this will come in a future update.

To actually enable the nested possibility, it must be done on the command line with xe.

Once your VM is created:

xe vm-param-set platform:nested-virt=true uuid=<vm-uuid>

To check this:

xe vm-param-get param-name=platform uuid=<vm-uuid>

You should have a line similar to below, with the nested-virt: true parameter visible:

nested-virt: true; timeoffset: 0; exp-nested-hvm: true; secureboot: false; device-model: qemu-upstream-compat; viridian: true; nx: true; acpi: 1; apic: true; pae:true; hpet:true

To deactivate it:

xe vm-param-remove param-name=platform param-key=nested-virt uuid=<vm-uuid>

For XOSTOR users:

• See the description for sm above.

(Reminder: XOSTOR is still in beta stage on XCP-ng 8.3)

Optional packages:

• Alternate Driver: Updated to newer version.
  • atlantic-module-alt:
    • Update vendor version of driver 2.5.12
    • Disable LRO for reliable bridging per README
    • More information about drivers and current versions is on the drivers page: (https://github.com/xcp-ng/xcp/wiki/Drivers).

Test on XCP-ng 8.3

From an up-to-date host:

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

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

What to test

Normal use and anything else you want to test. The closer to your actual use of XCP-ng, the better.

Test window before official release of the updates

~ 4/5 days

[bleader]

Home host updated successfully, no issue.

[flakpyro]

@gduperrey

installed on 2 test machines

Machine 1:
Intel Xeon E-2336
SuperMicro board.

Machine 2:
Minisforum MS-01
i9-13900H
32 GB Ram
Using Intel X710 onboard NIC

Both machines installed fine and all VMs came up without issue after.

[XCP-ng-JustGreat]

Latest test updates were applied to three-node home lab pool (3 x Dell OptiPlex SFF 7040 i7-6700/48GB RAM/256GB NVMe boot drive/TrueNAS Core 10Gbps-attached NFS shared storage) without incident. VMs appear to running normally, live migration between hosts works fine and no apparent problems so far.

[abudef]

The update went fine and everything is working fine.

@gduperrey said in XCP-ng 8.3 updates announcements and testing:

xapi: Re-enabled nested virtualization in 8.3, with the same limitations as in 8.2.

Since I keep bothering with nested virtualization here on the forum, I of course immediately tried the support in 8.3

Setup:

• HW XCP-ng 8.3
• • Nested XCP-ng 8.3
• • • Windows Server 2025
• • • Debian 12.9

Windows installation on the nested hypervisor went ok and the system seems to be working fine.
The problem occurred with Debian. ISO 12.9 netistall, UEFI was used. The system boots up and shows the notorious install screen: Graphic install, Install ... Regardless of the type of installation chosen, immediately after starting it, nested hypervisor XCP-ng 8.3 crashes and reboots. By the way, this problem with Debian is also on VMware - if I use nested XCP-ng 8.3 there, the Debian installation crashes it just the same.
