Possbile to port a KVM VM to Amazon EC2?

We currently have our own servers that have multiple KVM guests. If we ever decide to move to the Amazon EC2, would it possible to simply copy the VM image over or would I need to begin reconfiguring a new VM again on the cloud?

(It might sound silly but I'm still in the process of getting a grasp on the all the virtualisation/cloud stuff)

since you can import RAW images, you just need to make sure your guests are using raw. if they aren't RAW, you can use qemu-img convert to convert the images to RAW. This conversion will remove any snapshot chain you may have created using qcow2
