kvm on z/vm is out of scope for Ubuntu on s390x.

one may still want to investigate none-the-less in case something generic is uncovered.

Still seeing on Xenial 4.4.0-204.236 generic s390x on host kernel01. Looks like we recently added this test back into the report, which would explain lack of reports for this lately.

This did pass on host s2lp3
