- * When run under a hypervisor, a vcpu is always in one of three states:

- * enters the 'halted' state and remains halted until there is some work
- * pending for the vcpu (e.g. an alarm expires, host I/O completes on
- * behalf of virtual I/O). At this point, the vcpu enters the 'ready'
- * state (waiting for the hypervisor to reschedule it). Finally, at any
- * time when the vcpu is not in the 'running' state nor the 'halted'
- * state, it is in the 'ready' state.
- *
- * Real time is advances while the vcpu is 'running', 'ready', or

- * 'ready' state. Available time is the remaining time -- the vcpu is
