Ok, so, looking at your URL, a first difference is:

from vdsm import jsonrpcvdscli
 instead of
from vdsm import vdscli

a second one is that connect API differs:

In [3]: xmlcli = vdscli.connect()

In [4]: jsoncli = jsonrpcvdscli.connect()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-4-71cd6ff663fb> in <module>()
----> 1 jsoncli = jsonrpcvdscli.connect()

TypeError: connect() takes at least 1 argument (0 given)

so they're not really coming without changes :-)
