| 发明名称 | Virtual processor state management based on time values | ||
| 摘要 | A method includes, with a hypervisor, detecting that a virtual processor of a virtual machine has accessed a designated address, the designated address being associated with a time value, causing the virtual processor to enter a halt state for a period of time, and causing the virtual processor to exit the halt state after a period of time has passed, the period of time being based on the time value. | ||

| 主权项 | 1. A method comprising: with a virtual machine, determining that a virtual processor of the virtual machine expects to wait for a first period of time for an event; with a hypervisor associated with the virtual machine, detecting that the virtual processor has accessed a designated address, the designated address being associated with a table that maps time values to addresses; causing the virtual processor to enter a halt state for a second period of time; and causing the virtual processor to exit the halt state after the second period of time has passed, the second period of time being based on the time value. | ||
