OAM - SR-IOV 搭配 vmxnet3，或 SR-IOV 搭配 VIRTIO

在某些安裝中，可以為閘道混用、配對和提供不同的介面類型。這通常發生在您 OAM 沒有 SR-IOV 的情況下。此自訂組態會導致介面的順序紊亂，所以需要額外的步驟。

1. 記錄每個介面的 MAC 位址。

   VMware

   建立機器後，請移至編輯設定 (Edit Settings)，並複製 Mac 位址。

   

   KVM

   定義虛擬機器後，請執行下列命令：

   

2. 編輯使用者資料，並將 mac 位址固定為介面順序，如下所示：

   使用者資料 (Userdata)

   #cloud-config
    hostname: #_Hostname_#
    password: #_Console_Password_#
    chpasswd: {expire: False}
    ssh_pwauth: True

    - #_SSH_public_Key_#
    runcmd:
    - 'echo "[]" > /opt/vc/etc/vc_blocked_subnets.json'
    - 'sed -iorig "s/wan=\".*/wan=\"eth0 eth1\"/" /etc/config/gatewayd-tunnel'
    - '/var/lib/cloud/scripts/per-boot/config_gateway'
    - 'sleep 10'
    - '/opt/vc/bin/vc_procmon restart'
