Sandro,
The API hasn't changed between xmlrpc and jsonrpc. The only difference is format how we provide it. We need to update the API docs that we have and there is a bit of work (hopefully) scheduled for 4.0 to define api interface between the engine and vdsm with validation on both sides.
There is a bit of ongoing work to provide jsonrpc client for vdsm and you can code how to use it here [1]. There is a bit of work that needs to be done in order to merge it but you can take a look at start to play with it.
Thanks, Piotr
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 :-)
Small changes required since new jsonrpcvdscli is not one to one replacement. If you have any suggestions/improvements please let me know and we can change it to be more usable.

Hi, I'm looking at Bug 1228641 <https://bugzilla.redhat.com/show_bug.cgi?id=1228641> - [RFE] Switch from XML-RPC to JSON-RPC API and I'm searching google about "vdsm json rpc API documentation" without success.
I've seen /usr/share/doc/vdsm-jsonrpc/vdsm-api.html shipped within vdsm-jsonrpc rpm but it doesn't explain how to use the api.
/usr/lib/python2.7/site-packages/vdsmapi.py looks useless
/usr/share/vdsm/rpc/ are not public API but something only vdsm process should use.
The feature pages http://www.ovirt.org/Features/Design/JsonRpc3.5 and http://www.ovirt.org/Features/Design/JsonRpc are incomplete or outdated and miss proper testing section specifying how to test the API.
VDSM API pages are outdated or incomplete: http://www.ovirt.org/Vdsm_API http://www.ovirt.org/VDSM_Stable_API_Plan http://www.ovirt.org/Vdsm_API_Schema
Any hint on how to use VDSM JSON RPC API anywhere? Can someone please write a clear VDSM API reference documentation?
Piotr, as a kickstart, can you give me a code sample for connecting to vdsm and call getVdsCaps using jsonrpc?
