OEL is not supported on cr1.8xlarge. These instances run as HVM-base instances. All Oracle AMIs are PVM. For HVM you have to go with Windows, SUSE or RHEL for now. You can spin one of these up and install Oracle DB on them. There are ways to convert a PV AMI to HVM AMI, but whether Oracle will support you is another question. This applies to the other cluster compute instances types as well: CC2 and CG1. However, it is mostly likely someone wants to run the cr1 instance type as this is the largest memory footprint by far (244 GB). This size instance is great for in memory databases or large EBusiness Suite/Fustion installations.

Oracle Linux and HVM AMIs

EC2 instances life cycle
Here is a mapping of server hardware lifecycle to AWS EC2:
1. Start : On AWS - ec2-start-instances
Note: This is different then instantiating an instance for the the first time (from an AMI). The command for this is ec2-run-instances.
2. Reboot : On AWS - ec2-reboot-instances
(If a Linux/UNIX instance does not cleanly shut down within four minutes, Amazon EC2 will perform a hard reboot)
Note: Instance reboots are reboots of your virtual instance, and are equivalent to an operating system reboot. You can also reboot your instance from the operating system of your instance. More here: http://serverfault.com/questions/350581/differences-between-reboot-and-ec2-reboot-instances
3. Hard kill : ec2-stop-instances
4.AWS option : ec2-terminate-instances http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-TerminateInstances.html
Note: This would be like throwing away a machine but keeping the hard drive.
Tagging instances can be done at anytime using the ec2-create-tags command.
