Configure Compute Node on here.
By the way, it's necessarry to select plugin-software to configure Quantum and this example selects linuxbridge plugin.
[1] Install L2 Agent
# install from EPEL OpenStack, EPEL

[root@node01 ~]#
yum --enablerepo=epel-openstack-grizzly,epel -y install openstack-quantum-linuxbridge
[2] Configure L2 Agent
[root@node01 ~]#
quantum-node-setup --plugin linuxbridge

Quantum plugin: openvswitch
Please enter the Quantum hostname:
10.0.0.30
   
# specify QPID's hostname or IP address

Would you like to update the nova configuration files? (y/n):
y

Configuration updates complete!
