Everything I tried went OK, and logs look good to me.
I run in a few hiccups, which I mention for the sake of completeness: - VDSM refused to start or run VMs initially: libvirt config included relics from past environment on the same box, not JSON-rpc fault. Fixed with new config and (later) a reboot. - Trying recovery, Engine took longer than expected to sync up with VDSM. I have not hard data and feeling is not enough to file a BZ, so I didn't. - Still trying recovery, one and just one time Engine had stale data from VDSM (reported two VMs as present which actually aren't). Not sure it was related to JSON-rpc, can't reproduce, so not filed a BZ.
I need to partially amend this statement as, running more benchmarks/profiling, I got this twice in a row

On engine logs I see something alike this: http://fpaste.org/134263/
Since the above is way too vague to file a meaningful BZ, I'm now continuing the investigation to see if there is a bug somewhere or if it's a hiccup of my local environment.
I just want to note that I have been experiencing vague, intermittent jsonRPC issues with my environment also. I have filed 1143042 which I believe to be a symptom of unreliable communication. It seems to me that we have a definite problem to work out. -- Adam Litke
