OAM 接口和静态路由

如果要使用 OAM 接口部署网关，请完成以下步骤。

向虚拟机添加一个额外接口 (ETH2)。

VMware：如果管理/OAM 需要使用专用 vNIC，请添加另一个 vmxnet3 类型的 vNIC。您必须重复执行上一步，即，单击确定 (OK)，然后再次编辑设置 (Edit Settings)，才能记录 vNIC MAC 地址。

KVM：如果管理/OAM 需要使用专用 vNIC，请确保您具有名为 oam-network 的 libvirt 网络。然后，将以下行添加到您的 XML 虚拟机结构中：

…..
</controller>
<interface type='network'>
  <source network='public_interface'/>
  <vlan><tag id='#public_vlan#'/></vlan>
  <alias name='hostdev1'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x11' function='0x0'/>
</interface>
<interface type='network'>
  <source network='inside_interface'/>
  <alias name='hostdev2'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x12' function='0x0'/>
</interface>
<interface type='network'> 
  <source network='oam_interface'/>
  <vlan><tag id='#oam_vlan#'/></vlan>
  <alias name='hostdev2'/>
  <address type='pci' domain='0x0000' bus='0x00' slot='0x13' function='0x0'/>
</interface>
<serial type='pty'>
  <source path='/dev/pts/3'/>
  <target port='0'/>
  <alias name='serial0'/>
</serial>

使用添加的额外接口配置 network-config 文件。
