ConnectX-4 LX SR-IOV Config

[kevindd992002]

So I think I have a good grasp of how to configure SR-IOV using Nvidia's guide here and I was able to show the VF's already. The only thing I can't get my head to wrap around on is step 7 under section 2 (Enable SR-IOV on the MLNX_OFED Driver). Why do you need to change the MAC address of every VF when I see that the individual VF's already have random MAC's assigned to them? Or is this just optional?

But I think it's better to assign a static MAC, right? If you don't, then after a proxmox reboot, new random MACs will be assigned to your VF's?

但我认为分配一个静态 MAC 更好，对吧？如果您不这样做，那么在 proxmox 重新启动后，新的随机

是的，你是使用什么网卡？CX4还是CX5？
