High-performance virtual machine networking
摘要:
A method for conveying a data packet received from a network to a virtual machine instantiated on a computer system coupled to the network, and a medium and system for carrying out the method, is described. In the method, a guest receive pointer queue of a component executing in the virtual machine is inspected in order to identify a location in a guest receive packet data buffer that is available to receive packet data. Data from the data packet received from the network is copied into the guest receive packet data buffer at the identified location. A standard receive interrupt is raised in the virtual machine. Thus, the kernel places the data packet received from the network into a memory space accessible to the virtual machine without any intervention by a virtual machine monitor component of the virtualization software.
