Right, this does make checking the state/status of a storage domain
programtically troublesome.

I can get a list of all storagedomains, but only some of them will have.
the 'status' attribute.  If it doesn't have the status attribute, then I 
need to enumerate all of the datacenters, and for each datacenter, I can
list the storage domains, and check the status there.

Any reason the status of each storagedomain can't be present under
api/storagedomains?


Also, any tips on deleting 'unattached' domains via the python bindings?

>>> iso.delete()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/brokers.py", line 3180, in delete
    body=ParseHelper.toXml(storagedomain))
  File "/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/proxy.py", line 111, in delete
    return self.request('DELETE', url, body, headers)
  File "/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/proxy.py", line 128, in request
    last=last)
  File "/usr/lib/python2.7/site-packages/ovirtsdk/infrastructure/proxy.py", line 154, in __doRequest
    raise RequestError, response
ovirtsdk.infrastructure.errors.RequestError: 
status: 400
reason: Bad Request
detail: StorageDomain [host.id|name] required for remove
