Correct, it's only specific types of new hypervisors that use kvm
based, plus new HW like aarch64.

That being said I don't believe testing we can boot on xen is actually
useful these days for the AWS use case, it's likely different enough
that the testing isn't useful, we'd be much better testing that cloud
images actually work on AWS than testing if it boots on xen.
