vagrant up 時に出る network.service のエラー

はじめに

network.serviceのエラーに関して、色々いじった結果解決できたので備忘録として。
ちなみに内容は全くわかってないため、保証はできません。

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

# Down the interface before munging the config file. This might
# fail if the interface is not actually set up yet so ignore
# errors.
/sbin/ifdown 'enp0s8'
# Move new config into place
mv -f '/tmp/vagrant-network-entry-enp0s8-1494406484-0' '/etc/sysconfig/network-scripts/ifcfg-enp0s8'
# attempt to force network manager to reload configurations
nmcli c reload || true

# Restart network
service network restart

Stdout from the command:

Restarting network (via systemctl): [FAILED]

Stderr from the command:

Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

解決方法

vagrantへssh接続し、/etc/sysconfig/network-scripts/ifcfg-enp0s9のファイルを削除（移動の方がいいかもしれません）する。

$ vagrant ssh
[vagrant@localhost ~]$ sudo rm -rf /etc/sysconfig/network-scripts/ifcfg-enp0s9
[vagrant@localhost ~]$ sudo systemctl start network.service

移動の場合は以下のコマンドかな？

[vagrant@localhost ~]$ sudo mv /etc/sysconfig/network-scripts/ifcfg-enp0s9 ~/ifcfg-enp0s9
[vagrant@localhost ~]$ sudo systemctl start network.service

最後に

責任は持てませんが、誰かのお役に立てることを祈っております。

なお、下記のwarningに関しては解決しておりません（笑）

  default: Warning: Remote connection disconnect. Retrying...
  default: Warning: Connection reset. Retrying...

また、訂正すると思います。
