What I meant was, nowadays the cloud-hypervisor code we deal with is
under https://github.com/kata-containers/kata-containers/tree/main/src/runtime/virtcontainers/pkg/cloud-hypervisor,
firecracker also has its integration code as part of
https://github.com/kata-containers/kata-containers/tree/main/src/runtime/virtcontainers/pkg/firecracker.
With that in mind, govmm could actually be something like
https://github.com/kata-containers/kata-containers/tree/main/src/runtime/virtcontainers/pkg/qemu
(which doesn't exist yet).

Of course I'd like to have an abstraction that could actually handle
all the VMMs, but at this point I'm not sure whether it's possible, or
even worth it.
But that's something to be calmly evaluated and discussed, as future steps.

Did I answer your question, Tao?
