[Qemu-devel] [FOR 0.12 PATCH v3 21/21] Set default console to virtio on S390x

[Gerd Hoffmann]

All "normal" system emulation targets in qemu I'm aware of display
output on either VGA or serial output.

Our S390x virtio machine doesn't have such kind of legacy hardware. So
instead we need to default to a virtio console.
