Hi, I'm looking at Sean's change to run more of tempest on F20 [1]. To test it I'm using [2] -- it has shown is that tempest on F20 is *way* slower than on Ubuntu, to the point it times out. I compared logs from [3] & [4] to come up with a comparison [5], e.g. SecurityGroupsTestXML.test_server_security_groups goes from 28 seconds to 315 seconds (interestingly, it also showed up a bug that Ubuntu isn't preparing the images for boto tests [6]). I feel this has got to be due to some combination of nested virt v binary translation. Before I waste too much time, I thought I'd check with the experts for any thoughts? Is this a known issue?
