Unable to ping VM using OpenStack and Quantum(LinuxBride plugin) in a Single node set up

After booting a server an ip address is getting assigned and it is coming to 'ACTIVE' state.
But, when I tried to ping, it displays the below error.

root@vmquantum157:~# ping 5.5.5.12

I have installed and configure quantum with nova using "Quantum Admin quide".

No. I have not started the quantum-linuxbridge-agent.

Please suggest what could be the issue or cause.

Yes, the agent needs to be started and running. As you can see none of tap devices are associated to the relevant bridges.

quantum-linuxbridge-agent is very important to connect the vm with related bridges.
