[StarCluster] ERROR CREATING A NEW EBS VOLUME IN EUROPE FROM STARCLUSTER

[Andrea La Rizza]

Hy, I'm trying to create a new EBS volume from starcluster command, i 
give the command starcluster createvolume 60 eu-west-1a. My availability 
region in the confif file is eu-west-1. When I launch the command I 
receive the error:

ValidationError: image ami-9bf9c9f2 does not exist
!!! ERROR - image ami-9bf9c9f2 does not exist

But the ami above is not present anywhere in my config file, and 
searching for it I found is the default AMI for us-east-1. Why 
starcluster is not able to launch a device creator instance in my region 
and try to launch an AMI I didn't specify anywhere? Thanks.
