Restarting network (via systemctl):  Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.

위의 메세지에 나온대로 커맨드 입력한 결과도 한번 보여주시면 참고 하겠습니다.

# systemctl status network.service

# journalctl -xn

이렇게 에러나오는데요. 센트OS7이고요. 자유파파님 신경써주셔서 감사합니다. ㅠ

지유파파님 해결했습니다. ^^ 센트OS7 VM에서 64비트로 설정하니 뜨더군요.
아마 센트OS7 32비트 지원안해서 그런거 같습니다..

다행이네요 ^^;;

CentOS7부터는 32비트가 나오지 않을 겁니다.

도움이 되어 드리지 못해 죄송합니다.

아뇨.. 바쁘실텐데 여기 오시는 분들에게 답변 달아주시는 자유파파님께 큰 도움 되고 있습니다.
