Abstract
A method for reducing virtual machine preemption in a virtualized environment is provided. The method includes dispatching a virtual central processing unit (CPU) to run in an emulation mode on a real CPU until the real CPU exits the emulation mode, determining whether the virtual CPU has loaded a wait state, determining whether a remaining time slice of the virtual CPU as a result of the dispatching is below a predefined threshold in an event that the virtual CPU has loaded the wait state and rescheduling the virtual CPU with a full time slice in an event the remaining time slice of the virtual CPU is below the predefined threshold.
