Virtualizing a processor time counter during migration of virtual machine by determining a scaling factor at the destination platform

摘要

In one embodiment, the present invention includes a method for determining a scaling factor between a frequency of a first processor and a frequency of a second processor after a guest software is migrated from first processor to the second processor, and executing the guest software on the second processor using a virtual counter based on a physical counter of the second processor and the scaling factor. Other embodiments are described and claimed.
