Hello,

We have a pool with local storage, and when we perform updates we want to perform live migrations of all VMs on a particular host to a different host.

In XOA, we can display all VMs from a host, select them, and migrate them to a different host (within the same pool).
The issue here is that when we migrate multiple VMs at the same time, we notice a longer downtime in the last stage of the migration (I think it's the final pause before it moves over from old host to new host).
It goes a lot better when we migrate only 1 VM at a time.

For this reason, we'd like to set a custom concurrency when migrating multiple VMs.
I.e in this window we get when we select to Migrate:

An option to set concurrency to 1 would be very much appreciated so we can just select everything and the system will do its thing by itself one VM at a time.
Then a few hours later we can check and reboot the hypervisor when it is empty

Would something like that be possible?

Cheers!
Niels

Hello,

Unrelated to my other thread ( https://xcp-ng.org/forum/topic/7054/occasional-error-doing-live-migrations/1 ) there is another issue we sometimes see during live migrations.

This is an issue we mainly see on our larger VMs. That means starting at about 12 CPU cores / 48GB RAM, and usually these also have more local storage (500-800GB).

After the migration reaches 99-100% completion, the progress bar resets back to 0%. At this point, on our larger VMs, the VM will sometimes stop responding and sometimes fail the migration completely after 10-15 minutes of being unresponsive, or it will eventually come through after 5-10 minutes of being unresponsive.

In the logs, this is what we see:

Now I'm thinking the Xenops_interface.Xenopsd_error message might be a red herring since it occurs during the entire migration, and also continues after the VM has already started being responsive again

Here, the VM was unreachable from 16:55:30 until 17:00:28.
On our smallers VMs we don't really see the behaviour, but our larger VMs do have it quite often. This means we are always quite anxious to live migrate larger VMs since there's often a few minutes impact.

Is there anything we can do to debug this?

Hello,

We sometimes see a live-migration initiated through XOA fail. The failure is not immediately visible in XOA itself, but rather it looks like the task has cancelled.

We are migrating within the same pool and we also have local storage.
I've been digging through the xensource.log file (which is very very verbose) and I believe this is the relevant cause of the migration failure:

It doesn´t consistently happen, i.e. I can just retry the migration and it will work, but we aren't sure why it happens.
Does anyone have any idea?

@gduperrey said in Updates announcements and testing:

New Update Candidates (xen, xapi, templates)

• Xen: Enable AVX-512 by default for EPYC Zen4 (Genoa)
• Xapi: Redirect http requests on the host webpage to https by default.
• Guest templates:
  • Add the following templates: RHEL 9, AlmaLinux 9, Rocky Linux 9, CentOS Stream 8 & 9, Oracle Linux 9

Test on XCP-ng 8.2

From an up to date host:

For Xen, Xapi and Guest templates:

yum clean metadata --enablerepo=xcp-ng-testing
yum update xen-dom0-libs xen-dom0-tools xen-hypervisor xen-libs xen-tools xapi-core xapi-tests xapi-xe guest-templates-json guest-templates-json-data-linux guest-templates-json-data-other guest-templates-json-data-windows --enablerepo=xcp-ng-testing
reboot

Versions:

• xen-*: 4.13.4-9.29.1.xcpng8.2
• xapi-*: 1.249.26-2.2.xcpng8.2
• guest-templates-json-*: 1.9.6-1.2.xcpng8.2

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

No precise ETA, but the sooner the feedback the better.

Hello,

Is there any update on the ETA for this? Since it has been almost a month. We'll do the xcp-ng updates again soon and if these patches are close to release we will wait for them to prevent double work.

Cheers,
Niels

@eoin said in New patch - sudo:

@Darkbeldin Oh dear.... okay. Is every patch requiring reboot? If not, are there any ways to figure out if a patch needs reboot or not in XOA?

Just wanted to point out that you should always be prepped to reboot a host periodically, this is true for any hypervisor, it's not a good idea to not patch and just leave it running 24/7, especially in an environment where security matters.

Good thing is reboots of XCP-ng hosts don't really take that long.

While this is also what I'm used to, I have always wondered why it is advertised that no host reboots are required for patches, yet every update requires a patch:
https://xcp-ng.com/pricing.html under "Live Patching":

Enables administrators to patch hypervisors without needing to migrate, shut down or suspend VMs (no host reboots required)

@florent said in backup using http instead of https:

@KPS it's an easy win, so here is your christmas present
https://github.com/vatesfr/xen-orchestra/pull/6596
the message should show if nbd is really activated or not in XO, if there is a nbd enabled network on the host , and if the connection is successfull

Just wondering, could NBD also be used in the future for speeding up live migrations with local storage?

Hi,

Yes, indeed 8.2.1. Was a typo

I've updated the BIOS to 3.5. We'll have to see since it only happens every few months and I did not find a way to reproduce it.

Andrew: System Event Log (in the IPMI Interface) shows nothing. Memtest/Supermicro health check tool also shows no errors (sadly).

From this error, since it mentions tcp, could it indicate the cause might also be a NIC or NIC firmware?

Hello,

We have a host that will crash once every couple of months, taking down all VMs on it and rebooting itself after a few minutes.

We are running XCP-ng 8.1 on a Supermicro chassis. Supermicro's own health-check tooling reports the hardware is OK. We have a few other servers with exact same hardware that do not have this issue.

The crash-logs are very very verbose which is good but I am not sure what information is the most relevant. In the dom0.log I see the following which looks to be the cause:
