The "hypervisor's" field of the describe_instances response will continue to report Xen for all EC2 instances even though they're running under the new hypervisors. This virtualization type provides the ability to run an operating system directly on top of a virtual machine without any modification, as if it were run on the bare-metal hardware. Confusion may result from industry naming conventions for 64-bit CPUs. Although running a hypervisor inside another hypervisor (also known as cascading) is possible in different circumstances and under strict limitations - I can certainly understand In addition, for instances that are powered by the AWS Nitro Hypervisor, a small percentage of the instance memory is reserved by the Amazon EC2 Nitro Hypervisor to manage virtualization.
