we could get the st_obj in testcase then pass it into openConsole
If so, st_obj could be reused in the following statement in testcase
like:

st_obj = stream.getStream()
dom.openConsole(domname, None, st_obj)
receivedData = st_obj.recv(1024)
(the last statement probably resides in a registered stream callback
function via eventAddCallback API)

Wouldn't this actualy defeat the encapsulation that is provided in the StreamAPI class? With this change you can reuse the StreamAPI object for other actions later on too, without loosing the abstraction.

With the chagne you pushed:

You have to create a new StreamAPI object with DomainAPI.newStream() and then you have to extract the virStream object from that to pass it manualy to DomainAPI.openConsole(). IMO this will encourage to use the virStream object directly without the encapsulation that is provided by the StreamAPI class.

Thanks for the patch.
