Grizzly+Quantum+Linuxbridge does not create bridge interface

Hi,

I am trying to setup grizzly in a single host VM [Ubuntu 12] with quantum + linuxbridge. I have setup two seperate network [one static and one dhcp], done with keystone and glance but is stuck at Quantum.. After configuring the api, L3 agent, dhcp , linuxbridge plugin etc.. i restart all quentum and dnsmasq services. The service starts fine but there is no bridge created in ifconfig o/p. I can only see eth0 and eth1 along with lo. My quantum config files are:

At the point of configuring quantum , it should create a bridge and tap interfaces.. right?
