You can use the AWS CLI with Eucalyptus, e.g. for EC2:
aws --endpoint-url http://myeuca:8773/services/Eucalyptus ec2 describe-instances
the example assumes you have already configured credentials.
Question
Is there any way to use euca2ools natively on Windows or through Cygwin or is there any other tool compatible with eucalyptus which I could run under Windows ?
