It accelerates networking :) It allows guests direct but safe access to a portion of the NIC, thus avoiding going over the usual netback/netfront mechanism, and can result in significant performance increase, particularly on receive. It's aimed at 10Gbps. > 2)any requirement for harware nic? or other hardware platform? Yes, you need a NIC with plugin drivers which support the architecture. Right now there is just one option: the SMC TigerCard (available on Amazon). > 3)I've not found the code in Xen3.1 code set. so was it added to xen source code yet? It was merged for 3.2.
