66 * When run under a hypervisor, a vcpu is always in one of three states:
67 * running, halted, or ready. The vcpu is in the 'running' state if it
68 * is executing. When the vcpu executes the halt interface, the vcpu
69 * enters the 'halted' state and remains halted until there is some work
70 * pending for the vcpu (e.g. an alarm expires, host I/O completes on
71 * behalf of virtual I/O). At this point, the vcpu enters the 'ready'
72 * state (waiting for the hypervisor to reschedule it). Finally, at any
73 * time when the vcpu is not in the 'running' state nor the 'halted'
74 * state, it is in the 'ready' state.
75 *
76 * Real time is advances while the vcpu is 'running', 'ready', or
77 * 'halted'. Stolen time is the time in which the vcpu is in the
78 * 'ready' state. Available time is the remaining time -- the vcpu is
79 * either 'running' or 'halted'.
80 *
81 * All three views of time are accessible through the VMI cycle
82 * counters.
