	# Summary
	A few notes I took to see if I could use MacOS as Hypevirsor in a similar fashion to Linux
	I wanted to see how few addons were needed instead of using Parallels, Virtual Box, VM Fsion etc.
	The idea is to use QEMU, Hypervisor Framework (https://developer.apple.com/documentation/hypervisor) and some custom host networking.

	# Installations
	brew install qemu (For controlling Hypervisor Framework)
	brew install cdrtools (For making cloud init iso's)
	http://tuntaposx.sourceforge.net/download.xhtml (For customer tap based networking)
