Subject: [kvm-unit-tests PATCH 5/6] s390x: uv-guest: Test invalid commands
Date: Tue, 16 Mar 2021 09:16:53 +0000
Message-ID: <20210316091654.1646-6-frankja@linux.ibm.com> (raw)
In-Reply-To: <20210316091654.1646-1-frankja@linux.ibm.com>

Let's check if the commands that are not indicated as available
produce a invalid command error.
