Subject: [kvm-unit-tests PATCH v3 2/7] s390x: basic self test
Date: Mon, 22 May 2017 10:56:57 +0200 [thread overview]
Message-ID: <20170522085702.17856-3-david@redhat.com> (raw)
In-Reply-To: <20170522085702.17856-1-david@redhat.com>
Test if the general infrastructure is working. The test will fail until
we have proper sclp console output.
