Subject: [Qemu-devel] [Patch v4 20/30] s390x/kvm: allow runtime-instrumentation for "none" machine
Date: Mon,  5 Sep 2016 10:52:34 +0200	[thread overview]
Message-ID: <20160905085244.99980-21-dahi@linux.vnet.ibm.com> (raw)
In-Reply-To: <20160905085244.99980-1-dahi@linux.vnet.ibm.com>

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

Acked-by: Cornelia Huck <cornelia.huck@de.ibm.com>
