1. Combining tutorials in Enabling KVM virtualization for Raspberry Pi 2 and KVM on the Raspberry Pi2 enabled KVM on RPi 2.
2. sudo apt-get install bridge-utils uml-utilities
3. Using example script in Networking in QEMU
4. So the script looks like (I take no credit for this):
#!/bin/sh
# Disable the QEMU sound driver
export QEMU_AUDIO_DRV=none
# Basic system setup an ARM vexpress with 1 CPU, 256M of RAM
smp=1
cpu=host
ram=256
machine=vexpress-a15
# Where are the kernel and root images stored
dir=/home/pi/vms/linaro
bridge=br0
tap=$(sudo tunctl -u $(whoami) -b)
sudo ip link set $tap up
sleep 1s
sudo brctl addif $bridge $tap
