Because the generator part depends on many Java packages, building it for different platforms (for example for CentOS Stream 9) requires huge amounts of resources. Separating Python part allows us easy Python build for different Python version and probably it will allow us to add SDK into EPEL, which would simplify using it as a dependency for other projects (for example oVirt Ansible Collection) > With this change we lose all the history from the sdk examples, and we > break all the links to the example scripts. Try this search: > https://www.google.co.il/search?q=upload_disk.py If really needed we can add some README to current generator repo, but the most important link, which is official documentation, hasn't changed: http://ovirt.github.io/ovirt-engine-sdk/4.4/ Not to mention that finally after solving lots of issues with documentation generation it's up-to-date and aligned with SDK releases.

The examples and the generator are different parts of the python sdk. Why do we need to add another repository? We already have too many repositories. With this change we lose all the history from the sdk examples, and we break all the links to the example scripts. Try this search: https://www.google.co.il/search?q=upload_disk.py Why was this not discussed here before the change?

Both of these are a result of the patch this was ran for - which makes
host-0 use ovirt-node, for the he-basic suite.

[ovirt-devel] ovirt-engine-sdk repository changes
Hi, just bit summary of few changes in ovirt-engine-sdk repo [1]. There was the decision to split the SDK generator and the python SDK itself. So we created a new repository on GitHub called python-ovirt-engine-sdk4 [2]. We switched from Travis CI to GitHub Actions, because Travis no longer supported .org domain where we had our tests. The GitHub Actions automatically builds the SDK and pushes it to the new repo similar to the Go SDK. There were some issues with the documentation generator [3] so we switched to the new version of pdoc [4]. We migrated the SDK examples because the examples have nothing to do with the generator itself moved it to the new repository [6].

This is not the vm xml but the metadata xml.
Looking at the logs on both hosts:
[nsoffer@sparse ost]$ head -1 *vdsm.log
==> host0-vdsm.log <==
2021-08-08 13:16:04,676+ INFO (MainThread) [vds] (PID: 65169) I

- The hosts clocks are using different time zones (+ vs +0200) is
this intended?
- You are testing different versions of vdsm - is this intended?
We have about 60 errors:
$ grep 'Migration without shared storage is unsafe' host0-vdsm.log | wc -l
60
Looking at the first migration that failed, the vm xml is here:
2021-08-08 14:20:34,127+ INFO (vm/cde311f9) [virt.vm]

The relevant parts for storage are:

So we have one qcow2 disk on file storage, and one direct lun.
On the destination, the first migration attempt is here:

I think you should be able to find a dump of it in vdsm.log:
https://jenkins.ovirt.org/job/ovirt-system-tests_standard-check-patch/18650/artifact/check-patch.he-basic_suite_master.el8.x86_64/test_logs/ost-he-basic-suite-master-host-0/var/log/vdsm/vdsm.log
I think the first line of starting a migration is:

Makes sense. That's indeed what I was looking for, for VM cpu usage.

In "real", you might refer to two different things:
1. OST is a different environment - has ridiculously little memory/cpu, etc.,
or something else that is not expected or not recommended for a real system.
2. The _flow_ is not real. As in, it's unlikely that a real user will exit
global maintenance so quickly after starting the engine VM, without looking
around a bit more.
I agree with both - and even if it's eventually considered a real bug, I'd
not consider it severe. But just saying "OST is not a real system" is not
something I can completely agree with. We have a balance/tradeoff here between
trying to imitate "real systems" as accurately as possible and between doing
this efficiently/effectively. I do not think there is a deliberate design
choice to make it arbitrarily different from real systems.

Milan should be able to help with this.
In storage monitoring we avoid this issue by reporting actual=False
before we got the first monitoring results, so engine can wait for the actual
results.

If this is a real issue you should be able to reproduce this on a real system.

While trying to deactivate a host, the engine wanted to migrate a VM
(vm0) from host-0 to host-1. vdsm log of host-0 says:

Any idea?
