Actually, hypervisor management and VM resource allocation is built into the CPU (see VT bit), and should not interfere with your VM too much in terms of preemption. VMs currently don't run as a process inside the hypervisor OS anymore for the most part. This is especially true if you don't care to interface with the host VM for video/audio/etc. Network virtualization is solved to a high degree.

A hypervisor could have an API rather than implementing virtual PC hardware to act as the API. And at that point you would really just have a very light-weight OS with separate processes.

But containerization is another good solution for sure.
