KVM: S390: Add virtio hotplug add support
The one big missing feature in s390-virtio was hotplugging. This is no more. This patch implements hotplug add support, so you can on the fly add new devices in the guest. Keep in mind that this needs a patch for qemu to actually leverage the functionality. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
