New Features

Support for Paid AMIs
Amazon EC2 is introducing the ability to create Paid Amazon EC2 AMIs. This feature allows AWS developers to charge other EC2 users for the use of AMIs they have created and shared. Sellers of AMIs set the price, and their customers then purchase and are billed through Amazon for their use of these AMIs.

For more details, see the tech note Using Paid AMIs and the Demo Paid AMI. Also see the Technical Documentation (specifically, see the section "Launching and Using Instances > Paying for AMIs" in the Developer Guide).

Resolved Issues

Instances stuck "shutting-down" There was an issue where instances occasionally remained stuck in the shutting-down state for longer than expected. This is resolved.
Deregistered AMIs There was an issue where describing images returned deregistered AMIs for an undefined period after deregistration. This is resolved.

Known Issues

Instance limit New users are limited to a maximum of 20 concurrent instances. If you need a higher limit, contact
Creation of Paid AMIs is limited We are currently accepting only a limited number of partners who will be able to create Paid AMIs. Users interested in selling their Amazon EC2 AMIs through this program should send an e-mail to Please include your name, AWS account ID, company name, and a detailed description of your AMI.
Access to public NAT addresses from within EC2 EC2 instances cannot access instances in the new NAT environment through their public IP addresses; they must access the instances through their private IP addresses. The EC2 DNS servers will return the internal IP address when asked about an instance's public DNS name. In this way, DNS lookups that would resolve to a public EC2 IP address will be translated to the correct internal IP address. This only works when using the EC2 DNS servers from an EC2 instance.
Console output Some instances in the direct-addressing environment report a soft lockup error in the console output during boot. This is a false error that does not impact the successful booting of an instance.
Console output availability There were some reports of full console output not being available. Full console output is only guaranteed for instances that rebooted after this feature was released.
AMIs may launch if its S3 bundle was deleted. You may be able to launch an AMI after its bundle was altered or deleted from S3. We discourage deleting an AMI from S3 without also deregistering the AMI.
ec2-delete-bundle Misleading Error Message The ec2-delete-bundle operation currently returns an error when it attempts to delete an S3 bucket that is not empty. Despite this error, the files within this bundle are successfully deleted.
