XCP-ng 8.2 updates announcements and testing

olivierlambert

It's better to update on all nodes, because you won't have to remember which one is patched or not. The risk is very low, we aren't expecting any side effect.

Hello,
I tried on small vdi's and my restore and cr problems solved with this update. I start large vdi restore and I will post results when done. Thank you.

Edit: Iarge vdi restore and cr job (1.3 terrabyte) complete succesfully. Also delta backup jobs still working without error. Thank you again.

Thanks for the tests. I have pushed the vhd-tool package to the updates repository now, for everyone.

Update candidate: qlogic-netxtreme2 and qlogic-netxtreme2-4.4.0+10-modules

target: XCP-ng 7.5 and XCP-ng 7.6
reasons for the update: updated driver to fix various issues including kernel oops
packages:
- qlogic-netxtreme2-7.14.49-1.x86_64.rpm
- qlogic-netxtreme2-4.4.0+10-modules-7.14.49-1.x86_64.rpm
description of the changes:
- an updated driver was needed to fix various regressions in hardware support for NICs using the bnx2x driver, regressions that started with XenServer 7.2.
- we had a test package available but an official driver disk has been issued upstream, so we'll release this one instead: https://support.citrix.com/article/CTX239113
install: yum install --enablerepo='xcp-ng-updates_testing' qlogic-netxtreme2-7.14.49-1.x86_64
testing tips: test if you have the required hardware. If you haven't, just test that it installs correctly and nothing unexpected breaks.
reboot: not required if you know how to unload (rmmod) and re-load (modprobe) the driver from the command line. Else a reboot will do it for you.

Did a test on 5 physical hosts (from 7.5 to 7.6): everything is working correctly.

We should probably release this in "prod" for Monday

stormi

Xen security update released for 7.5 and 7.6RC1.

The qlogic-netxtreme2 package will stay in updates_testing a bit longer to let people test it.

stormi

I have now pushed the qlogic-netxtreme2 package to updates for 7.5 and 7.6.

Update candidate: xcp-emu-manager

target: XCP-ng 7.5 and XCP-ng 7.6
reasons for the update: fix a VM migration issue that occurs mostly with loaded VMs
packages:
- 7.6: xcp-emu-manager-0.0.6-1.x86_64.rpm
- 7.5: xcp-emu-manager-0.0.3-1.1.x86_64.rpm
description of the changes:
- Many users reported seemingly random migration failures. Community testing alllowed to find that it was consistently reproducible by forcing high resource usage such as with this command: stress --cpu 1
- The problem was caused by the fact that xcp-emu-manager, our replacement of the proprietary emu-manager component from Citrix that handles suspend, resume and migrate operations, did not know how to handle progress messages that arrived when not expected anymore, near the end of the migration process. The fix consists in ignoring those messages when the next step of the process has already started.
- Fixes https://github.com/xcp-ng/xcp/issues/72
install: yum install --enablerepo='xcp-ng-updates_testing' xcp-emu-manager
testing tips: migrate VMs, especially loaded ones. Or artificially stress linux VMs with the stress command then migrate them.
reboot: no reboot required, no toolstack restart.

For this specific update, please report your results there: https://xcp-ng.org/forum/topic/522/unable-to-migrate-live-vms-after-upgrading-from-xcp-ng-7-4-to-7-5

stormi created this issue in xcp-ng/xcp

closed Migration can fail especially for loaded VMs #72

stormi

The update for 7.6 has been made available as a regular update, as xcp-emu-manager-0.0.6-2.x86_64.rpm. It should prevent most migration crashes, but can still get stuck when the VM is heavily loaded. Instead of failing directly, it will now try to wait for a low enough activity to resume the process. We're still working on it to bring a better, complete solution.

An update to XCP-ng 7.6 has been pushed: xcp-emu-manager-0.0.9-1, that fixes all known migration issues (well, except this bug from XenServer: https://github.com/xcp-ng/xcp/issues/111). Update for XCP-ng 7.5 is being prepared.

oallart created this issue in xcp-ng/xcp

closed Live migrating HVM linux (and others?) with storage migration from any older release to 7.6 works but vm dead #111

stormi

Updates to XCP-ng 7.6 have been pushed today:

xapi-* and xcp-featured : add ZSTD compression support for faster export and backups
openvswitch : fix wrong log rotation configuration (https://github.com/xcp-ng/xcp/issues/100)

Reminder: how to update.

New update candidate for XCP-ng 7.6. It adds support for NFS 4.1, that has been contributed by a member of the community and already merged upstream in the XAPI project!

Install it:
yum update sm sm-rawhba --enablerepo='xcp-ng-updates_testing'

Revert:
yum downgrade sm sm-rawhba

Thanks in advance for your feeback!

U are never ALONE

@stormi I am watching you.

maxcuttins

We are the watchmens

tuxen

I'm here. Alive n' kickin'

stormi

So did anyone install the update candidate for sm, check that they see no obvious regression and ideally test NFS 4.1 support?
