pve安装intel网卡（支持sr-iov）：
参考：
PVE开启SR-IOV记录 https://koolshare.cn/thread-158441-1-1.html
Proxmox VE(PVE)开启IOMMO并开启网卡(82576)SRIOV功能 https://blog.csdn.net/shuye216/article/details/108942595
首先pve需要安装intel igb网卡驱动，然后将物理网卡（母网卡）虚拟为VF（virtual function），最后直通给虚拟机，然后在虚拟机中安装网卡驱动，疑问母卡还是否可用？？？？？ 所有VF加起来的带宽不能超过母卡的pcie-x1或pcie-x4或pcie-x16的物理带宽（也就是说不要模拟过多的vf）
echo "options igb max_vfs=6,6,6,6,6,6" > /etc/modprobe.d/igb.conf
我这里有6个intel 82576网卡，每个网卡虚拟出6个，总共是36个虚拟网卡
