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).
