OAM - 使用 vmxnet3 的 SR-IOV 或使用 VIRTIO 的 SR-IOV

在某些安装中，可以为网关混合、匹配和提供不同的接口类型。如果您的 OAM 不具有 SR-IOV，通常会发生这种情况。此自定义配置需要执行额外的步骤，因为这会导致接口的顺序被打乱。

1. 记录每个接口的 MAC 地址。

   VMware

   创建计算机后，转到编辑设置 (Edit Settings)，然后复制 Mac 地址。

   

   KVM

   在定义虚拟机后，运行以下命令：

   

2. 编辑用户数据并将 Mac 地址锁定到接口顺序，如下所示：

   用户数据

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