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
Quantum run on Diablo flows diff from Original Diablo:
回覆刪除1. Running QuantumServer contain database 'ovs_quantum' which store all network info. All running QuantumAgent inquire NetInfo. (i.e. nova-database no longer store NetInfo.)
2. Api send 'run_instance' to Compute, with argument 'net_ids: [net1_id, net2_id]' which pass to Network.
3. Network inquire all needed NetInfo from QuantumServer.
4. Quantum running on Compute and Network will poll QuantumServer every 2s about 'vlan tag info', then use 'ovs-vsctl ...' to add vlan on port.
