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.

Thanks, subscribed. What is puzzling me is that on my environment everything seemd OK initially (hence the initial report), even the mass start went OK, once. Will update the BZ with my findings, open a new one otherwise.
