Abstract: In one embodiment, a method includes transitioning control to a virtual machine (VM) from a virtual machine monitor (VMM), determining that a VMM timer indicator is set to an enabling value, and identifying a VMM timer value configured by the VMM. The method further includes periodically comparing a current value of a timing source with the VMM timer value, generating an internal event if the current value of the timing source has reached the VMM timer value, and transitioning control to the VMM in response to the internal event without incurring an event handling procedure in any one of the VMM and the VM.

Abstract translation: 在一个实施例中，一种方法包括将控制从虚拟机监视器（VMM）转移到虚拟机（VM），确定VMM定时器指示符被设置为启用值，并且识别由VMM配置的VMM定时器值。 该方法还包括周期性地将定时源的当前值与VMM定时器值进行比较，如果定时源的当前值已经达到VMM定时器值，则生成内部事件，并且响应于内部事件将控制转换到VMM 而不会在VMM和VM中的任何一个中引发事件处理过程。
