IMHO it is a bit strange for the vhost to default to the IP. You may 
want to raise that with the qpid folks.

Is there anything unusual in the RabbitMQ logs? Check the LOG_BASE 
directory  - C:\Documents and Settings\User\rabbitmq\log if you are 
using the default settings.

Also, which version of the amqp0-8.xml spec file are you using? The one 
that comes with the qpid distribution is not the official version. 
Replace it with the official version from 
https://jira.amqp.org/confluence/download/attachments/720900/amqp0-8.xml. 
I don't think that's the problem in this particular case though.
