Quantum + Openstack(Diablo)

Follow http://wiki.openstack.org/QuantumOVSDemo instructions
The nova services(api, scheduler, network, compute...) and quantum server+client can run up easily.
Note:
After installed needed packages and downloaded all source.
Before ./nova-quantum run, we need
1. create volumes group 'nova-volumes'
2. check glance version, needed 'glance_2011.3~rc' and 'python-glance_2011.3~rc'
3. check dnsmasq version

Demo:
exe "./nova-quantum run, that will generate 10 screens."
switch to screen 10 "test",
exe "python sqo.py create-network net1:net2"
exe "python sqo.py create s1=net1,net2"
then generate a vm with 2 interface, eth0 belong to net1 and get ip 10.0.0.2/24,
eth1 belong to net2 and get ip 10.0.1.2/24
