Reference: bnc#888173
Force the use of vm-install on s390. The viewer in virt-manager
and virt-viewer needs a graphics adapter defined in the VM to show
the display correctly. On s390 you can't have a graphics adapter
(you get the error 'No PCI buses available'). Vm-install gets
around this problem by starting an xterm window in which to run the
VM.
