I saw this last week when I was pulling over the instance_id changes ...
vishy had a fix in his branch that changed the return type of the name
method from long to a string ... following from the logs:

2010-10-07T17:58:51  <kevnfx> vishy: regarding "startswith", I'm having the same exception.  Appears that virDomainLookupByName is being passed in a long rather than a string.  Wasn't instance_id recently changed?
2010-10-07T18:00:07  <vishy> kevnfx: there is a fix posted, it involves changing nova/db/sqlalchemy/models.py
2010-10-07T18:00:32  <vishy> the name method on instance should return str(self.internal_id)
2010-10-07T18:00:45  <kevnfx> vishy: cool .. thanks!

There was  duplicate bug that was being fixed simultaneously, in any
case, what I experienced has been fixed.
