I've started an EC2 instance and installed the ec2-api-tools. Environment variables (JAVA_HOME, EC2_PRIVATE_KEY, EC2_CERT) are set up.
Running ec2-describe-instances doesn't return anything. According to the EC2 command line reference information on all currently running (and terminated) instances should be returned. What's going wrong?
In general ec2-describe-images -o self -o amazon works, so the EC2 tools are working. Adding explicitly -K and -C parameters to ec2-describe-instances doesn't change the situation.
