The specific functionality you describe is available in mainframes, although they are designed to always run a hypervisor. You can't practically do it in the PC world because the operating systems either expect to use a virtualisation interface, or they expect direct control over the hardware. The latter will also give better performance.
Some virtualisation environments do have hardware passthrough. A good example would be having a high performance PCIE video card which is passed through to to a guest for gaming. You can also use real storage instead of files pretending to be storage, although this is less flexible (eg no snapshots).
My recommendation is to use Ubuntu as your host OS and run Windows as a VM guest.
I want to be able to run multiple OSs/Installations-of-the-same-OS on a single machine such that I can swap between "running" OSs - meaning, I want to have one OS sleep while I use the other.
So, if I have windows and ubuntu on the same machine - I dont want to reboot, I want to just put one to sleep and wake the other one up...
OR Ideally - I want to be able to run them side-by-side in some manner that is greater than a VM running on top of the other... My System76 laptop has dual SSD drives in it, I'd like to have both machines running, with half the resources dedicated to each, and have my KVM switch between them.
Anything come clsoe to this?
