Linus, Sorry for taking so long to respond. The cluster machines were removed by rollback which was caused by exception: 2013-08-04 11:08:33.907 3542 INFO savanna.service.instances [-] Cluster 'cluster-test-01' creation rollback (reason: unexpected type <type 'NoneType'> for addr arg) Looks like currently code hides the exception stacktrace, so I can't tell what caused it. My suggestion would be to change the code to print the stacktrace. That way it will be much easier to diagnose the issue.
