"privileged" is ill-defined in the context of kata containers.  One of
the main uses of privileged containers is to manage things on the
host, which is fundamentally incompatible with Kata's approach of
running the container in a VM.

There are some edge cases where privileged kata containers are used,
but in general it's really not clear what permissions and abilities
such a container should have.

As a consequence, I'd recommend not attempting to use Kata for
privileged containers.
