SR-Iov Introduction: (Reference: http://docs.oracle.com/cd/E38902_01/html/E38873/glbzi.html)We know that the vt-d function can be directly assigned to the device to allow the virtual machine to use an I/O device that achieves similar physical machine performance, but there is a drawback to using vt-d: A device can only be used by one client, so is there any way to make the device performance, so that multip

In the above (http://blog.csdn.net/yeasy/article/details/39178187) mentioned the Virtual Machine network traffic access exchange problem. This article describes the interaction between a VM and a server's physical Nic. Generally, a server runs dozens of virtual machines, and the demand for computing and network is amazing. The former boosts the development of current multi-core technology, while the latter cannot simply be implemented using multiple NICs. Imagine that every VM requires 10 Gbi
