Se for implementar os gateways com uma interface OAM, complete os seguintes passos.
- 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>
- Configure o ficheiro network-config com a interface adicional.
