From: David Hildenbrand <da...@redhat.com>
Linux crashes right now if maxmem > mem is specified on the command line.
On s390x, the guest can hotplug memory itself right now - very weird -
and e.g. Fedora 27 will simply add all memory it can when booting.
So now, we have at least the same behavior on TCG and KVM.
