Não consigo obter o NAT padrão para funcionar. Não atribui um IP (DHCP) ao convidado (centos) usando a rede. Pelo que posso dizer, a rede está funcionando.
Se eu usar a rede macvtap que se conecta com o físico, posso obter uma conexão com a Internet sem problemas. Qual resolve 1/2 meu problema, o outro 1/2 é que eu também quero ter host < - > comunicação com os hóspedes também.
