[Openstack] Associating VM to a quantum network

Hi Alisson,

I assume you are following the directions as described at:
http://docs.openstack.org/incubation/openstack-network/admin/content/index.html?


If so, then you have QuantumManager enabled in Nova and when you ran
"nova-manage create network", this should have reached out to quantum to
create a network, then stash that quantum network uuid in the nova db for
future use.

Can you try accessing quantum directly to see if that networks exist?
 Since you did not specify a "--project" when creating the network with
nova-manage, QuantumManager will create the network with a quantum
tenant-id set to the --quantum_default_tenant_id flag (defaults to
"default").

So assuming the default, try running:

bin/cli list_nets default

What networks does this show?

My best guess is that it will show only a single network:
cbbbf92d-26d3-4a8d-8394-bb173fc35cbb, meaning one of your two nova networks
show above was not created on Quantum.  Is it possible that you created
that network before enabling QuantumManager using the --network_manager
flag?  If so, you would need to delete that old network, and recreate it
while Nova is using Quantum Manager.  If both were created with
QuantumManager enabled, then it is possible one of them failed.  Can you
find the network manager logs from the period when you ran the 'nova-manage
create network' commands?

Thanks,

Dan
