I think that the Mach microkernel at least partially solves this

It isn't really a virtual machine as Mach has no instruction set, only
a C API.

However, it does supply many of the same services that the JVM offers
to Java programmers; threads, virtual memory, memory protection, file
systems, network protocols, and device support.

A JVM that is implemented as a Mach server with JNI calls into the
Mach API could have the features you are looking for.
