摘要： An approach is provided in which a data traffic module executing on a network interface card receives a data packet initiated by a first virtual machine with a destination at a second virtual machine. The data traffic module identifies one or more physical path translations corresponding to a logical connectivity that is independent of physical topology constraints of a physical network. In turn, the data traffic module encapsulates the data packet with the one or more physical path translations and sends the encapsulated data packet to the second virtual machine over the physical network.

摘要： An approach is provided in which a hardware accelerated bridge executing on a network adapter receives an ingress data packet. The data packet includes a destination MAC address that corresponds to a virtual machine, which interfaces to a software bridge executing on a hypervisor. The hardware accelerated bridge identifies a software bridge table entry that includes the destination MAC address and a virtual function identifier, which identifies a virtual function corresponding to the software bridge. In turn, the hardware accelerated bridge sends the data packet from the hardware accelerated bridge to the software bridge through the identified virtual function.

摘要： An approach is provided in which a discovery system receives a migration request to move a virtual machine that executes on a first system. The discovery system identifies a first network adapter corresponding to the first system, and identifies hardware state data used by the first network adapter to process data packets generated by the virtual machine. In turn, the discovery system identifies a second network adapter that is compatible with a native format of the hardware state data, and migrates the virtual machine to a second system corresponding to the identified second network adapter.

摘要： An approach is provided in which a hypervisor provisions switch resources on a network interface card, which includes a virtual switch and a physical port. The hypervisor invokes a switch control module on a virtual machine, which provides control information to one or more of the switch resources. In turn, one or more of the switch resources utilize the control information to direct data packets between a source virtual machine and a destination virtual machine over one or more virtual networks that are independent of physical topology constraints of a physical network.

摘要： An approach is provided in which a local module receives a data frame initiated by a first virtual machine and has a target destination at a second virtual machine, which executes on a destination host system. The local module identifies a destination local port ID and a destination global queue pair number corresponding to the second virtual machine. In one embodiment, the destination local port ID corresponds to the destination host, but the destination global queue pair number is independent of the destination host. The local module includes the destination global queue pair number and the destination local port ID in an overlay header and encapsulates the data frame with the overlay header, which results in an encapsulated frame. In turn, the local module sends the encapsulated frame through a computer network to the second virtual machine.
