I wonder why they call it a container. Looks like virtual machine to me: each guest runs its own kernel, uses hardware virtualization.

It is somewhat muddying the waters, but I wouldn't exactly call it a full fledged VM either...

Containers are the new hotness, while virtual machines are so five years ago.

(buzzword compliance is far more important than most of us want to admit..)

These guests will run their own kernel, but not ship with one (in the image). So in a way, all the benefits of a KVM segregation and the leanness of a container image.

I want to read how they handle the networking setup though.

Because Kata Containers offers, "The speed of containers, the security of VMs". Regular VMs do NOT offer the (deployment and startup) speed of containers... nor do they use the container userland tools to manage... nor do they use OCI container images. Kata Containers do all of that.

Regular VMs (VMware & such) do come in OCI format: I've built them (and delivered them to customers).

Not really the best of both worlds, if you still have the overhead of a new kernel at runtime, which is when it matters...
