I'd recommend to try virt-install, see 
http://kvmonz.blogspot.com/p/knowledge-use-virt-install-for-kvm.html. 
virt-install will set up the VM in a proper way.

You will need to invoke virt-install with --arch=s390x if your running 
on an x86 box and make sure you have the qemu-system-s390x package 
installed.

Chance for success will probably increase with the currency of the QEMU 
used.

The invocation you've reported above doesn't instantiate a virtio disk 
and network interface (which are the only device types supported for 
s390x. Similary virtual CD/DVD must be on virtio-scsi for s390x. Again, 
virt-install and virsh are your friends here.
