The Virtual Machine Queue (VMQ) is a hardware virtualization technology for the efficient transfer of network traffic (such as TCP/IP, iSCSI or FCoE) to a virtualized host OS. VMQ technology was patented in 2010 by Daniel Baumberger of Intel Corp. A VMQ capable NIC can use DMA to transfer all incoming frames that should be routed to a receive queue to the receive buffers that are allocated for that queue. The miniport driver can indicate all of the frames that are in a receive queue in one receive indication call. The VMQ interface supports: * Classification of received packets in NIC hardware by using the destination MAC address to route the packets to different receive queues. * NIC ability to use DMA to transfer packets directly to a virtual machine’s shared memory. For more information about shared memory, see NDIS 6.20 Memory Management Interface. * Scaling to multiple processors by processing packets for different virtual machines on different processors. == Virtual Machine Queue Architecture == The NDIS virtual machine queue (VMQ) architecture provides advantages for virtualization such as: * Virtualization impacts performance and VMQ helps overcome those effects. * VMQ supports live migration. * VMQ co-exists with NDIS task offloads and other optimizations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VMQ」の詳細全文を読む スポンサード リンク
