Hi all,

We are deploying OpenStack Grizzly, but we have some problem with the
Quantum configuration related with the BigSwitch plugin.

Previously, we achieved to use the openvswitch plugin, but with the
BigSwtich plugin, the Quantum log shows the following message:

*2013-07-01 12:14:14    ERROR [quantum.openstack.common.rpc.amqp] Exception
during message handling
Traceback (most recent call last):
line 430, in _process_data
    rval = self.proxy.dispatch(ctxt, version, method, **args)
line 43, in dispatch
    quantum_ctxt, version, method, **kwargs)
line 138, in dispatch
    raise rpc_common.UnsupportedRpcVersion(version=version)
UnsupportedRpcVersion: Specified RPC version, 1.1, not supported by this
2013-07-01 12:14:14    ERROR [quantum.openstack.common.rpc.common]
Returning exception Specified RPC version, 1.1, not supported by this
endpoint. to caller*

This message is repeated every X seconds. We are not sure which endpoint it
refers to, nor where is the RPC version defined. Any idea?

Thank you all,

Best regards,

Adrián Roselló
