coordination #54617: [functional][y][pvm][epic] Enable more scenarios to run on powerVM Backend
[y] Enable btrfs+warnings on powerVM
We continue extending coverage on powerVM, based on the priority provided in https://confluence.suse.com/pages/viewpage.action?pageId=340623739
We already have quite some test suites related to the storage enabled, so it's time to cover other things.
NOTE: gnome is not important on powerVM as is not used there according to our knowledge, so we should not test it.
- btrfs+warnings scenario is enabled on powerVM with validation modules
- Test plan is updated accordingly
