Networking in a virtual computing infrastructure
First Claim
1. A method for networking in a cloud computing environment having a plurality of computing nodes, the method comprising:
- upon receiving authorization, communicating with a plurality of virtual machines to provide at least one virtual network to service to the plurality of virtual machines, wherein each of the plurality of virtual machines communicate with a virtual network layer at a virtual interface via at least one virtual Ethernet (vEthernet);
associating a first virtual Media Access Control (MAC) address to a first virtual machine;
associating a second virtual MAC address to a second virtual machine;
storing a mapping between the first virtual MAC address and a first Internet Protocol (IP) address of a first host machine upon which the first virtual machine executes;
storing a mapping between the second virtual MAC address and a second Internet Protocol (IP) address of a second host machine upon which the second virtual machine executes;
receiving, at an operating system of the first host machine from the first virtual machine, a particular packet that specifies the first virtual MAC address as a source and the second virtual MAC address as a destination;
in response to receiving the particular packet, determining, in the operating system of the first host machine, and based on the mapping between the second virtual MAC address and the second IP address, that the particular packet is to be routed to the second host machine;
encapsulating, at the operating system of the first host machine, the particular packet within encapsulating data that specifies the second IP address as a destination; and
sending the encapsulating data containing the particular packet through a physical network interface of the first host machine.

Abstract
A cloud computing environment having a plurality of computing nodes is described. Upon receiving authorization, a plurality of virtual machines may be communicated to provide at least one virtual network to service to the plurality virtual machines. Each of the plurality of virtual machines communicates with a virtual network layer at a virtual interface via at least one virtual Ethernet (vEthernet), An IP gateway to a network is provided to the plurality of virtual machines. Communications between the fP gateway and the network are facilitated. Communications between a network control layer and at least one network are routed.

17. A cloud computing environment having a plurality of computing device nodes, wherein each device node comprises:
-
one or more central processing units; a host operating system, at least one virtual interface, and network control, and a storage device storing instructions which, when executed by the one or more central processing units, cause the one or more central processing units to perform; associating a first virtual Media Access Control (MAC) address to a first virtual machine; associating a second virtual MAC address to a second virtual machine; storing, a mapping between the first virtual MAC address and a first Internet Protocol (IP) address of a first host machine upon which the first virtual machine executes; storing a mapping between the second virtual MAC address and a second Internet Protocol (IP) address of a second host machine upon which the first virtual machine executes; receiving, at an operating system of the first host machine, from the first virtual machine, a particular packet that specifies the first virtual MAC address as a source and the second virtual MAC address as a destination; in response to receiving the particular packet, determining, in the operating system of the first host machine, and based on the mapping between the second virtual MAC address and the second IP address, that the particular packet is to be routed to the second host machine; encapsulating, at the operating system of the first host machine, the particular packet within encapsulating data that specifies the second IP address as a destination; and sending the encapsulating data containing the particular packet through a physical network interface of the first host machine. - View Dependent Claims (19, 20)
