MAX_VM_CREATION_TIME = The maximum amount of time we should wait for the first node in the system to go from ‘pending’ to ‘running’ and acquire a public IP. Our current VM size is about 10GB, so this means that in Eucalyptus it could take up to 30 minutes to start if the image wasn’t cached.

SLEEP_TIME = The amount of time to sleep between invocations of ec2-describe-instances when starting up the first node in the system. This should definitely not be lower than 5 seconds, as Eucalyptus 2.0.3 or newer will interpret it as a possible replay attack.

IP_REGEX = The regular expressions to use to find the public and private IPs (or FQDNs in case of EC2).
