Help needed to debug problem with the maas provider

[Julian Edwards]

Hi,

I've got problems when running a "juju deploy".  The client end reports that 
it has succeeded but the provisioning agent on the master node bails out when 
it tries to start another node as below.

As far as I can determine, a value of None is being massed for machind_id when 
calling start_machine (I know this because the code path always calls 
set_machine_id, so getattr in the cloud-init validation check is seeing a 
None).  My knowledge of the rest of juju is not good enough to understand why 
this would be, so can someone help me figure this out please?

Thank you
J.
