thanks Greg,

To try this out, I've redeployed the new testenv image and ran 35
overcloud jobs on it(32 passed), the average time for these was 130
minutes so unfortunately no major difference.

The old kernel was
3.13.0-33-generic #58-Ubuntu SMP Tue Jul 29 16:45:05 UTC 2014 x86_64
the one one is
3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64

 Also its worth noting the test I have been using to compare jobs is the
 F20 overcloud job, something has happened recently causing this job to
 run slower then it used to run (possibly upto 30 minutes slower), I'll
 now try to get to the bottom of this. So the times may not end up being
 as high as referenced above but I'm assuming the relative differences
 between the two clouds wont change.

 thoughts?
 Derek

This kernel definitely had the kvm bugs Greg and I exprienced in the
past

 the one one is
 3.13.0-35-generic #62-Ubuntu SMP Fri Aug 15 01:58:42 UTC 2014 x86_64
 

Darn. This one does not. Is it possible the hardware is just less
powerful?
