EC2 Nested Virtualization

Question

As I understand, nested virtualization is currently only available on Metal EC2 instances.

I see in this question that Graviton 2 uses the ARMv8.2 architecture, which does not have native support for nested virtualization, but Graviton 3 is based on ARMv8.4 that should support this:

- https://repost.aws/questions/QU8NxrQuk3Rla42meRIear6g/does-graviton-3-support-nested-virtualization

Will I be able to use nested virtualization on EC2 instances with Graviton 3 that are not metal?

Answer

Currently EC2 VMs do not support nested virtualization for any architecture. To run your own hypervisor on EC2, you have to use *.metal instances. From there you could do nested virtualization, but at that point there's no need as you have the entire machine to work with.
