CopyMsWindowsAmiState

• Object

Defined in:

lib/scripts/ec2/copy_mswindows_ami.rb

Overview

Initial State: Retrieve all information on this AMI we need later on

             and set some parameters such as the Availability Zone
- Snapshot ID from this AMI
- Volume size from this AMI
- Availability Zone

NB: less modification if we get the AZ from the launched instance NB: if we do not own this AMI, we have no snapshot, so we must launch an instance
