Se for implementar os gateways com uma interface OAM, complete os seguintes passos.

  1. Adicione uma interface adicional à VM (ETH2).

    VMware: se for pretendido um VNIC dedicado para gestão/OAM, adicione outro vNIC do tipo vmxnet3. Tem de repetir o passo anterior, ou seja, clicar novamente em OK e depois em Editar definições (Edit Settings) para poder criar uma nota do endereço MAC vNIC.

    KVM: se for pretendido um VNIC dedicado para gestão/OAM, certifique-se de que tem uma rede libvirt chamada oam-network. Em seguida, adicione as seguintes linhas à estrutura XML da VM: 

    …..
</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>
  2. Configure o ficheiro network-config com a interface adicional.
