20	/** @page pg_vmm VMM - The Virtual Machine Monitor
21	*
22	* The VMM component is two things at the moment, it's a component doing a few
23	* management and routing tasks, and it's the whole virtual machine monitor
24	* thing. For hysterical reasons, it is not doing all the management that one
25	* would expect, this is instead done by @ref pg_vm. We'll address this
26	* misdesign eventually.

48	* @sections sec_vmm_limits VMM Limits
49	*
50	* There are various resource limits imposed by the VMM and it's
51	* sub-components. We'll list some of them here.
52	*
53	* On 64-bit hosts:
54	* - Max 8191 VMs. Imposed by GVMM's handle allocation (GVMM_MAX_HANDLES),
55	* can be increased up to 64K - 1.
56	* - Max 16TB - 64KB of the host memory can be used for backing VM RAM and
57	* ROM pages. The limit is imposed by the 32-bit page ID used by GMM.
58	* - A VM can be assigned all the memory we can use (16TB), however, the
59	* Main API will restrict this to 2TB (MM_RAM_MAX_IN_MB).
60	* - Max 32 virtual CPUs (VMM_MAX_CPU_COUNT).
61	*
62	* On 32-bit hosts:
63	* - Max 127 VMs. Imposed by GMM's per page structure.
64	* - Max 64GB - 64KB of the host memory can be used for backing VM RAM and
65	* ROM pages. The limit is imposed by the 28-bit page ID used
66	* internally in GMM. It is also limited by PAE.
67	* - A VM can be assigned all the memory GMM can allocate, however, the
68	* Main API will restrict this to 3584MB (MM_RAM_MAX_IN_MB).
69	* - Max 32 virtual CPUs (VMM_MAX_CPU_COUNT).
