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