Subject: [ovirt-users] OVIRT-3.5-TEST-DAY-3: replace XML-rpc with JSON-rpc
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

(this is a runner script using ovirt sdk for python, source is available on demand and
will be
published anyway soon[ish])
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.
