action #127523

Updated by okurz 10 months ago

## Motivation 
 In #125993 a generic "s390-kvm" worker class was introduced to prevent too long waiting for s390x worker ressources. Some problems were found failing jobs for yet unknown reason hence qam reverted to using s390-kvm-sle12 for the time being. The job failures should be investigated and problems should be fixed to be able to use "s390-kvm" worker class wherever you don't care about the specific s390x hypervisor OS version. 

 ## Acceptance criteria 
 * **AC1:** Most s390x kvm tests use an openQA "machine definition" that uses the generic "s390-kvm" worker class 
 * **AC2:** Current OSD openQA s390-kvm workers all have the generic class "s390-kvm" 

 ## Suggestions 
 * Understand and fix test failures mentioned in #125993 or #127337 
 * Verify common openQA tests can work on "s390-kvm" worker class 
 * Use "s390-kvm" in production job templates
