Needles:
os-autoinst/os-autoinst-needles-opensuse#641
and
https://gitlab.suse.de/openqa/os-autoinst-needles-sles/merge_requests/1322
should be also merged, in order that changes in "lib/Installation/Partitioner/FormattingOptionsPage.pm" will not break RAID tests.
(Looks like QAM doesn't use this library, so I don't see the need to duplicate needles for older sle versions.)

There is an issue with the validation_fs_table module on hyperv, that will be investigated separately.

Validation test on osd under name "msdos":
https://openqa.suse.de/tests/overview?distri=sle&version=15-SP2&build=139.4&groupid=129
Validation that raid_gpt doesn't break:

Please make the minor changes that i am asking. Also rename new_table.pm to something else. i am struggling to find something to suggest.

Last but not least write a small description on your commit of what is this for and you have done(help the reviewer to understand whats going on)

@sofiasyria LGTM and this PR had already a lot rounds of reviews so it should be fine even if we miss something. A couple of things:
Could you comment failures in your verifications (even just saying that are not related with this task) but at least to discard any other problem.
In the meantime some other reviewer gives ok, if you want you can prepare YAML Job group PR and paste link in the first comment.

I'm a bit confused now, we already have test suite enabled in the job group, but neither this PR is merged nor any of the needles one. I believe we should not rush into enabling not finished tests not to pollute results for the daily builds.

I am not sure if enabling means adding the test to the Job Group. I did that because otherwise I could not run the tests with isos post, only with refspecs. Is there another way?

cloning from another job of the target arch and modifying its params like YAML_SCHEDULE, etc. As Rodion mentioned, we should not enable in the overview things not working/finished, openqa-clone-custom-git-refspec is what we normally use, for very peculiar scenarios like Multi Machine, isos post could be useful. Otherwise we have test failing in the overview and there is a automation in place to report those failures to release managers plus our own effort to label them, so it is always better try the other path first.

Missing points before merging that we could spot:

• Rerun verifications (optionally comment the ones failing if related or not with this task)
• Fix commit message

Good job, let's try it!
