Bo,

Thanks for your reply.

My colleagues and I are working on some POC and it is based on Kata & K8s.
The new features you mentioned will definitely help us. However, we are
still at the very early stage and trying to prove that cloud hypervisor is
truly what we are looking for compared to firecracker which does not have
these features yet.

Regards

Wilson
