Abstract

This disclosure generally relates to time and timer techniques that may be used to virtualize one or more virtual machines. In an example, it may be possible to save and restore a timer of a virtual machine while preserving timer information associated with the timer (e.g., an expiration time, whether the most recent expiration has been signaled, and the enable bit, etc.). For example, a first mode may enable restoring a timer based on a previously-existing enable bit, thereby retaining the state of the timer (e.g., whether the timer is programmed to fire and/or whether the most recent expiration has been signaled). By contrast, a second mode of setting a timer may automatically set the enable bit, thereby automatically enabling the timer to fire, as may be expected by a virtual machine when setting a timer.
