commit 2a9bf9ca069c3476ec3c320ea1276f86158fe3fd

kvm tools: Virtio console support
This patch adds simple virtio console support to the hypervisor.
NOTE, NOTE, NOTE: Please add something like this to your /etc/inittab file:
T2:23:respawn:/sbin/getty -L hvc0 9600 vt100
to get a virtio console login.
