PVE下CX4121A网卡SRIOV，添加VF网卡不识别

hamajun

各位大佬，如题，指点一下方向

PVE下，CX4121A网卡SRIOV，添加VF网卡给飞牛，开机不识别；

把（CX4121A）VF网卡添加给openwrt和Ubuntu都可以正常运行。


换X710网卡添加VF网卡给飞牛没有问题。



虚拟机开机时有个报错，不知道是不是这个问题？（这个报错AI回复，不影响）

我是cx542b可以给飞牛用

卖螺丝的卡应该不会有什么大问题吧，这玩意用户量很大

12代以前家用主板的芯片组对这个卡的兼容性不好，sriov开到6组左右就会报错了。

也有可能是飞牛自己的问题。

amd 5800h，最多4个
x710的vf，没有问题，可能是飞牛的问题
