環境

  • 網卡：Intel 82599EB 10 Gigabit
    • module：
      • ixgbe
      • ixgbevf

測試指令

  • 載入網卡 module：
    • 僅載入網卡 
      modprob ixgbevf
modprob ixgbe
    • 載入網卡及 8 個 VF 
      modprob ixgbe max_vfs=8
    • module 設定： 
      vim /etc/modprobe.d/ixgbe.conf
    • 網卡設定： 
      vim /etc/udev/rules.d/70-persistent-net.rules
  • 列出 ixgbe 網卡 module： 
    lsmod | grep ixgbe
  • 列出 82599 網卡及 VF： 
    lspci | grep 82599
lspci | grep Virtual
  • 卸載網卡 module：
    • 卸載網卡前，要先檢查 VM 是否已經全部關閉： 
      virsh list --all
    • 卸載網卡： 
      modprob -r ixgbe

實驗

  • node 04、05
    • 實體 eth
      • eth2：右邊
      • eht4：左邊
