[Qemu-devel] [Patch v1 20/29] s390x/kvm: allow runtime-instrumentation f


From: David Hildenbrand
Subject: [Qemu-devel] [Patch v1 20/29] s390x/kvm: allow runtime-instrumentation for "none" machine
Date: Tue, 2 Aug 2016 13:59:06 +0200

To be able to query the correct host model for the "none" machine,
let's allow runtime-instrumentation for that machine.
