Methods and systems for a virtual environment are provided. A method includes receiving a packet from a first virtual machine at a virtual switch; determining if the packet is destined to a second virtual machine by comparing a destination address to a mapping data structure maintained by the virtual switch; transferring the packet to a first virtual function of a device assigned to the first virtual machine by directly mapping the first virtual function to the first virtual machine; the first virtual function initiating a direct memory access (DMA) operation to transfer the packet to the second virtual machine based on a logical memory address of the second virtual machine that is received from a second virtual function; and using the DMA operation to transfer the packet to the second virtual machine.

Method and system for virtual machine communication

Method and system for processing a command received from a processor executable computing entity from among a plurality of computing entities of a computing system that interfaces with a device is provided. The method includes receiving the command by a command processing module executed by a processor of the computing system; generating a command object for the command by the command processing module, where the command object format does not change regardless of a computing entity type or a command type; placing the command object in a command queue maintained by the command processing module; sending the command to a device in a same context as a context of the computing entity, when the command object is a first command object in the command queue with the command that is ready to be sent to the device; and sending the command to the device in a different context as the context of the computing entity, when the command object is not the first command object in the command queue with the command that is ready to be sent to the device.
