We are getting a lot of tempest build failures as I reported in https://bugs.launchpad.net/tempest/+bug/1056213. Informally, it seems about 10% of the time it fails. I was unable to reproduce it in my local environment. How can we figure out what is going on here? Also, even the runs that pass show a n-cpu log that is strewn with ERRORs and stacktraces, some of them pretty scary looking. I filed a bug about this three weeks ago https://bugs.launchpad.net/nova/+bug/1046870 but it has not gotten any attention. -David
