- Desativar a interfave virbr0
A interface virbr0, ou "Virtual Bridge 0" é usada pelo NAT (Network Address Translation). Fornecida pela biblioteca libvirt e ambientes virtuais é algumas vezes usada para se conectar com redes externas.
Foi necessário desativar a bridge virbr0 usando o Network Manager.
Nova placa
- A placa de rede MAC 00:06:4F:61:C4:5A aparenta problemas (físicos, porém pode ser apenas configuração)
- Nova placa externa foi instalada MAC 00:0A:5E:5C:2C:04
Entretanto ela está sendo nomeada como eth2 (talvez causando problema, pois não consigo ativá-la).
Comando úteis:
- atualiza nomes e dados de placas (não fez diferença)
[user] update-pciids
