Abstract:
A mechanism for virtual time stamp counter acceleration is disclosed. A method of embodiments of the invention includes setting a virtual machine (VM) time stamp counter (TSC) to a hyper-fast rate, receiving control of the VM due to a VM exit caused by the VM issuing an instruction that reads the VM TSC, and adjusting the VM TSC with a value of an offset counter associated with the VM.
