19	*
20	* The HM manages guest execution using the VT-x and AMD-V CPU hardware
21	* extensions.
22	*
23	* {summary of what HM does}
24	*
25	* Hardware assisted virtualization manager was originally abbreviated HWACCM,
26	* however that was cumbersome to write and parse for such a central component,
27	* so it was shortened to HM when refactoring the code in the 4.3 development
28	* cycle.
29	*
30	* {add sections with more details}

167	* either. The fallback to raw-mode will not happen if /HM/HMForced is set
168	* (like for guest using SMP or 64-bit as well as for complicated guest like OS
169	* X, OS/2 and others).
