摘要：
Available buffers in the memory space of a guest operating system of a virtual machine are provided to a network interface controller (NIC) for use during direct memory access (DMA) and the guest operating system is notified accordingly when data is written into such available buffers. These capabilities obviate the requirement of using hypervisor memory as a staging area to determine which virtual machine to forward incoming data.
