Overall this patch looks really good Sandy. Nice tests, and some really
helpful comments in there (as usual).

Generally speaking, I think a few whitespaces cleanups would make a make this
patch even better (in particular lining up arg-lists). Not a huge deal,
obviously, but worth mentioning.

In terms of design and implementation, I think it looks good. This matches up
with what we whiteboarded (AFAICT), so I'm all for it.

Imported but not used.

Might be slightly easier to read with tuple-unpacking (also, passing 1 to
split in case the value has a '=' in it):

    for cap in caps:
        key, value = cap.split('=', 1)
        zone[key] = value

Might be better if args aligned:

    super(ComputeManager, self).__init__(service_name="compute",
                                         *args, **kwargs)

Same as above:

                ['hypervisor=xenserver;kvm', 'os=linux;windows'],
                'Key/Multi-value list representng capabilities of this zone')

> 88 +from nova import log as logging

Might be worth using the LOG pattern here to get more specific logging:

    LOG = logging.getLogger('nova.manager')

Spacing. Might be better as:

       update_service_capabilities is called with non-None values.

    def __init__(self, host=None, db_driver=None, service_name="undefined"):

Couple spaces ---> thataway (to line up with open paren +1)

Could use a bit of formatting work:"Created '%(exchange)s' fanout exchange "
               "with '%(key)s' routing key"),
             dict(, key=self.routing_key))

Although, this might be personal preference on my part, so, if that change
doesn't look good to you, please feel free to ignore! :-)

Spacing, a couple of spaces <---- thattaway.
