I have a few related questions I am having difficulty finding a firm answer for:
Does the XNU kernel have a KVM port in progress already? I know KVM was ported to the illumos kernel. How feasible is to have the same done for XNU?
Does the XNU have an equivalent to something like KVM? If not, what would be the most efficient* way of setting up a minimal VM host based off the XNU kernel?
*By efficient, I mean:
- Minimal RAM usage
- No need for a Desktop Environment
- No need for a Window Manager
- No need for X11 or equivalent
- The only necessary processes running should be related to the VM hosting process and networking

XNU in general, or macOS specifically? – user1686 – 2016-11-10T05:50:44.943
1@grawity I purposefully didn't mention Mac OS. I would prefer not to limit options as far as possible. But that said, I am envisaging a multi OS platform based on Apple Mac hardware. I am a QA and it would be great to be able to switch between operating systems on the fly with as minimal overhead as possible.
Update: I didn't consider that the OS might make a difference to the porting process. From my limited knowledge the kernal would be modified, and then a package on the OS would be able to interface with the kernel. Is that not how it works? Do we also need to make a change to the OS? – Dean Kayton – 2016-11-10T12:28:44.290
