From 2998ffee245e3a141ce1b6fca127744c3e19dc63 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Fri, 29 May 2015 13:22:12 +0200 Subject: [PATCH] s390: disallow memory hotplug for the s390-virtio machine That machine type doesn't currently support memory hotplug, so let's abort if it is requested. Reason is, that the virtio queues are allocated for now at the end of the initial ram - extending the ram is therefore not possible.
