In the wiki page we describe 3 groups of drives, those with CI run
by the OpenStack project (Group A), those with CI run by 3rd party
vendors (Group B) and those with no CI at all (Group C)

  https://wiki.openstack.org/wiki/HypervisorSupportMatrix#Driver_Testing_Status

The _do_quality_warnings method is intended to print a warning for
any libvirt driver combination that is in Group C.

After S390(x) has a 3rd party CI system running regularly & reasonably
reliably, then you can submit a change to add S390X to the architecture
list in _do_quality_warnings.

Daniel
