Kamarul,
The status shown on the dashboard is confusing. Under Router Detail
section, it shows Status as Active. But under Interfaces it shows as DOWN
but Admin status as UP (refer the cut-paste below).
Also i see following error message in /var/log/quantum/dhcp-agent.log:

+++++++++++++++
Stderr: "sudo: no tty present and no askpass program specified\nSorry, user
quantum is not allowed to execute
......
 ERROR [quantum.agent.dhcp_agent] Unable to sync network state.
+++++++++++++++
