I've an Havana IaaS composed by:

1 controller node
1 network node
1 compute node

and using Neutron as networking, and rabbitmq as AMQP.

The network node runs the agents (dhcp, l3, openvswitch, metadata). The 
controller runs Keystone, glance, Nova APIs, Neutron server.

The compute node runs Nova Compute.

I've followed this guide: 
to perform a migration from Havana to IceHouse.

After migration (without any apparent error) I get a lot of errors for 
the several services related to the AMQP.

For example in the neutron server's log I see:


In the nova api's log I see:


and a similar one for Nova conductor:


Did I miss something ? I didn't see anything directly related to AMQP in 
the guide cited abobe.
