DB error in Cisco plugin

[Sumit Naiksatam]

When the Cisco plugin is configured to support L3 extension, the get_network is failing with the following error:
2012-09-17 19:52:22 DEBUG [quantum.db.dhcp_rpc_base] Network list requested from vmwc

    raise errorclass, errorvalue

The likely reason is that the l3 db is not getting initialized correctly.
