Hi-

Please help troubleshoot the issue

I have written a fake agent with the study from the dhcp agent.

The rpc agent daemon is running with the below errors.

But I have missed some bits of information with respect to the rpc
communication.

In the log, I have the following errors.

2012-10-31 16:14:38     INFO [quantum.agent.fake_compute_agent]

The error is " AttributeError No such RPC function
'get_host_instances_info' "

I have written the method to support the agents method, by following the
DHCP agent method "get_active_networks".

The following files are modified by adding the RPC function method.


db/db_base_plugin_v2.py:1268:    def
_get_host_instances_info(self,context,filters=None,fields=None):
db/fakecompute_rpc_base.py:47:    def get_host_instances_info(self,
context, **kwargs):
db/fakecompute_rpc_base.py:50:        LOG.debug('[FakeComputeCallbackMixin]
get_host_instances_info :: Getting instances info for host %s.....', host)
db/fakecompute_rpc_base.py:55:        return
plugin.get_host_instances_info(context, filters=filters)


Being a newbee for this code base, Unable to plot what is the BIT that is
missing in this rpc communication.

Please help me to troubleshoot this issue.

Thanks in advance...
