I'm slightly confused as you are both talking about AWS Nitro and XEN. I know Nitro moved off of Xen and was roughly based on KVM.

Also, are you talking about Annapurna in it's pre-acquisition form or new one? AWS talks about new custom asics and multiple ARM SoCs on their Nitro system.

The comment is quite clear, there are three networking technologies in use at amazon. Nitro was never xen, Nitro is KVM with Annapurna add in cards.
