Answer 1

Acabei de me deparar com o mesmo problema imediatamente após a instalação do RHEL 7.0. Estranhamente, uma reinicialização sem alterações na configuração eliminou o problema.

De alguma forma, quando o RHEL surgiu após a instalação, aparentemente a rede estava em estado desordenado, e precisou de outra reinicialização para ficar limpa.

    

Answer 2

Reiniciar o NetworkManager funcionou para mim:

systemctl stop NetworkManager
systemctl start NetworkManager

Eu não tentei, mas acho que essa frase deve ter o mesmo efeito:

systemctl restart NetworkManager

    

Answer 3

sempre que você tiver esse problema, tente encontrar o endereço MAC usando o comando ifconfig

e copie o endereço de hardware e cole-o em

vi /etc/sysconfig/network-scripts/ifcfg-eno16777736
