s390: use virtio_console for KVM on s390
This patch enables virtio_console as the default console on kvm for s390. We currently use the same notify hack as lguest for early console output. I will try to address this for lguest and s390 later. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
