+
+    1. pci id 总线位置 ;
+    2. 设备名称；
+    3. 制造商和型号 id 8086:3ec6 ,大家注意到只要是intel的设备都是8086,那是因为这个8086就是制造商的代码;
+    4. 电源状态, rev 07 rec 10,如果是断电是rev ff, 我记得大概是这样。

+# sr-iov 设置
+**sr-iov 科普**
+    
+    SR-IOV 技术是一种基于硬件的虚拟化解决方案，可提高性能和可伸缩性。SR-IOV 标准允许在虚拟机之间高效共享 PCIe（Peripheral Component Interconnect Express，快速外设组件互连）设备，并且它是在硬件中实现的，可以获得能够与本机性能媲美的 I/O 性能。SR-IOV 规范定义了新的标准，根据该标准，创建的新设备可允许将虚拟机直接连接到 I/O 设备。
+**sr-iov 常用领域**
+1.主要是网络设备；
+2.显卡设备， Intel比较新的显卡也支持这个技术;
+## 查看设置是否支持 sr-iov
+    一般来说10G以上的网卡才支持这个技术,显卡也是特定设备才支持。Intel 12代以后的核显好像支持,具体自己查一下,我手头没有设备所以没有太关注这个。
