XCP-ng 8.3 updates announcements and testing

Greg_E

I see this for my 8.2 pool this morning, I'll kick it off when we all go into a meeting so it will be done when we finish.

manilx

@Greg_E Updated 3 pools @business (3 Intel hosts, 2 EPYC hosts) all OK with stats. Also 1 pool @home (2 Intel Protectlis) all OK with stats.

archw

I updated the master pool...all went well. I updated one of the other hosts. After it rebooted, I got lots of messages about "Async.VM.clean_shutdown: 8%" on the various VMs.

My bad....XO was a two builds behind and well as XO was not up to date.

I updated to commit 95e72 and updated XOA version to 5.106.2 and all is well.

User error on my part but I hope this helps someone.

@Greg_E

No issues so far with my production system (8.2.x) and this batch of important updates, these are on Intel Silver (v2?) processors.

But my system is so vanilla that I doubt there would be any issues anyway. The only "out of normal" thing I've done today is storage migrate a VM off of one Truenas to another so I can apply some updates to Truenas. Then I'll migrate everything to the updated server so I can update the "main" storage.

Can't migrate VHD between pools

I updated my Intel test host/pool at the New update candidates for you to test! 8 days ago.

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

I then ran the New security update candidates for you to test! 2 days ago

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

I was no longer able to migrate a VHD from my Intel "test" host/pool to my AMD "production" host/pool
My thought was I had to wait for the "release" update.

When the update was published, on my "production" host I ran New update candidates for you to test! and New security update candidates for you to test!
(why didn't I just run yum update ??)
Still no migration

Tried to update my hosts

[10:23 x1 ~]# yum update

I then checked the software versions and there is a diff. in
git_id , date , xapi_build and db_schema

[10:23 x1 ~]# xe host-list params=software-version
software-version (MRO)    : product_version: 8.3.0; product_version_text: 8.3; product_version_text_short: 8.3; platform_name: XCP; platform_version: 3.4.0; product_brand: XCP-ng; build_number: 8.3.0; git_id: 0; hostname: localhost; date: 20250507T15:15:51Z; dbv: 0.0.1; xapi: 25.6; xapi_build: 25.6.0; xen: 4.17.5-13; linux: 4.19.0+1; xencenter_min: 2.21; xencenter_max: 2.21; network_backend: openvswitch; db_schema: 5.786

[10:20 x2 ~]# xe host-list params=software-version

What is the next step to fix this?

ph7

Now I am not sure if I did run the New update candidates for you to test!
Is there a way to force the updates?

gduperrey

@ph7 As David mentioned, the security updates were released yesterday. They are no longer in the candidates repository, but in the updates repository.

Note that the updates in the testing repository have not yet been released. They include a more recent version of the XAPI. This could explain why you can no longer migrate this VHD between your test and production environments.

Are you trying to perform a live migration or with the VM powered off?

ph7

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

Are you trying to perform a live migration or with the VM powered off?

No live migration, different pools, VDI migration only, powered off.
Warm migration is working.

It's OK, I can wait for the release

Andrew

@ph7 @gduperrey With current updates: Cold (VM off) migration works for me. Live migration, when forced due to incompatible CPU fails (badly, host toolstack restart required).

With the VM off, normal VM/VDI migration worked for me in the following process (VM power on after each migration, and then off again, as a test):

XCP 8.2 Intel (Pool 1) -> XCP 8.2 Intel (Pool 2) -> XCP 8.3 Intel (Pool 3) -> XCP 8.3 AMD (Pool 4) -> XCP 8.3 Intel (Pool 3)

Note: Each host/pool uses local storage. Software versions on hosts match for the same version of XCP. @ph7, looks like you need to yum clean all and yum update again.

@Andrew

looks like you need to yum clean all and yum update again.

Tried it but it didn't work
And I ran the rm -rf /var/cache/yum

[13:09 x2 ~]# yum clean all

And rebooted

Cold migration doesn't work, but Warm migration does.
No panic, I can wait for the release

stormi

Just to be sure, is there an issue for us to investigate here, or expected failure due to version mismatch?

ph7

@stormi
If You are asking me, I can run the New update candidates for you to test! on my "production" home lab server if the testing repo still exist

stormi

Yes update candidates that were not urgent security fixes are still in the xcp-ng-testing repository (and more is coming soon, today or on
monday).

ph7

@stormi
I ran the xcp-ng-testing and now the migration seems to work
