When attempting to create a remote deployment target in AWS using both the coreOS and Kubernetes clusters, I receive similar errors:
Provisioning cluster in Amazon EC2
AMI Used: ami-212e0911

The interface defaults to t2.micro which according to this requires a VPC: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html
As a quick fix, changing the default selection would work for the time being, but ultimately, adding the ability to select/create a VPC would be really helpful.
