How reproducible:
Sometimes

Steps to Reproduce:
1. You can try run something like: # aeolus-cleanup && aeolus-configure -p ec2 && aeolus-cleanup && aeolus-configure -p ec2 && aeolus-cleanup && aeolus-configure -p ec2
I guess in second round you will get an error 
  
Actual results:
Sometimes failed

Expected results:
Always passed
