Some embodiments of the invention provide a failover capability in a computer system that employs multiple paths to transfer information to and from a network, such as a computer system that performs virtualization, without introducing a new driver component to provide this capability. For example, some embodiments of the invention provide a networking virtual switch client capable of direct communication between a networking stack implemented by a virtual machine operating system and components comprising either a direct path or a synthetic path to a network interface controller coupled to a network. The networking virtual switch client may be capable of determining which of the paths to employ for a given communication, such as by determining that a synthetic path should be employed if a direct path is not available.
A system comprising a computing device and at least one program module that are together configured for performing actions for routing information over a first path or a second path between a network and a virtual machine, where the first path comprises the network coupled to a network interface card coupled to a switch client coupled to a networking stack coupled to the virtual machine, where the second path comprises the network coupled to the network interface card coupled to a switch module coupled to a virtual machine bus coupled to the switch client coupled to the networking stack coupled to the virtual machine, the actions comprising:
A method performed on a computing device, the method for routing information over a first path or a second path between a network and a virtual machine, where the first path comprises the network coupled to a network interface card coupled to a switch client coupled to a networking stack coupled to the virtual machine, where the second path comprises the network coupled to the network interface card coupled to a switch module coupled to a virtual machine bus coupled to the switch client coupled to the networking stack coupled to the virtual machine, the method comprising:
At least one computer storage device storing instructions that, when executed by a computing device, cause the computing device to perform actions for routing information over a first path or a second path between a network and a virtual machine, where the first path comprises the network coupled to a network interface card coupled to a switch client coupled to a networking stack coupled to the virtual machine, where the second path comprises the network coupled to the network interface card coupled to a switch module coupled to a virtual machine bus coupled to the switch client coupled to the networking stack coupled to the virtual machine, the actions comprising:
