Subject: [Qemu-devel] [Patch v2 20/29] s390x/kvm: allow runtime-instrumentation for "none" machine
Date: Mon,  8 Aug 2016 17:32:49 +0200	[thread overview]
Message-ID: <1470670378-53732-21-git-send-email-dahi@linux.vnet.ibm.com> (raw)
In-Reply-To: <1470670378-53732-1-git-send-email-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>
