Hypervisors and physical machines and their respective methods for measuring performance in hypervisors and physical machines

摘要

A method for enabling performance measurement between a virtual machine and a peer node executed by a hypervisor executing the virtual machine and a method executed by a physical machine comprising the hypervisor are provided. The method performed by the hypervisor is to intercept (110) a packet sent from or destined to the virtual machine, including the destination address to the virtual machine or peer node, and hypervisor time into the packet. Including determining whether a stamp should be inserted. The method includes inserting a hypervisor timestamp into the packet when it is determined to insert a hypervisor timestamp into the packet (120), and forwarding the packet to the destination according to the destination address (130).
