Abstract

In one embodiment, a method includes receiving a request to transition control to a virtual machine (VM) from a virtual machine monitor (VMM), calculating an offset value, receiving, during operation of the VM, a request for a current value of the timer, adjusting the current value of the timer based on the offset value, and providing the adjusted timer value to the VM.
