Add suport for JSON as input and output to RESTAPI.
JSON REST API is accessible in 3.4.0-0.11.beta3.el6 and seems to present all the information the xml API does.
Please ignore my previous comment, more complicated procedure needs to be followed for RFE.
This is an automated message: moving to Closed CURRENT_RELEASE since oVirt 3.4.0 has been released.
