Known Issues

IssueDescription
Query Version of ModifyInstanceAttribute The Query API ModifyInstanceAttribute request does not allow the block-device-mappings to be modified, and the user-data attribute cannot be modified if it already contains data.
Paid AMIs Backed by Amazon EBS AMIs backed by Amazon EBS are not currently supported by Amazon DevPay.
Windows AMI launch times Windows AMIs that are backed by Amazon S3 take longer to launch than Linux/UNIX instances due to larger AMI sizes and multiple reboots.
Windows AMI sizes Installing software on Windows AMIs that are backed by Amazon S3 can cause them to become large and easily reach the 10 GB limit. Before bundling, check the size of the C:\ volume.
Limitation on drive mapping There are limitations on devices available for storage attachment. For more information, go to How to Attach the Volume to an Instance in the Amazon Elastic Compute Cloud User Guide.
Security group limitation AuthorizeSecurityGroupIngress does not allow port ranges for group grants when using the command-line tools or the Query API. This is only supported through the SOAP API.
Instance limit New users are limited to a maximum of 20 concurrent instances, but many of our customers use hundreds or thousands of instances. If you need a higher limit, go to http://www.amazon.com/gp/html-forms-controller/ec2-request.
