I need to partially amend this statement as, running more benchmarks/profiling, I got this twice in a row INFO:root:starting 100 vms INFO:root:start: serial execution INFO:root:Starting VM: XS_C000 INFO:root:Starting VM: XS_C001 INFO:root:Starting VM: XS_C002 Traceback (most recent call last): File "./observe.py", line 154, in <module> data = bench(host, 'XS_C%03i', first, last, api, outfile, mins * 60.)

(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.
