//変更すべきところ
/etc/hosts
/etc/sysconfig/network
/etc/sysconfig/network/ifcfg-eth0
//あとユーザーを作るとか、rootのパスワード変えるとか・・
macアドレスは上記のVM設定ファイルから取ってVMのifcfg-eth0につける
useradd nymph -g users
    • 追記.MACアドレス違う場合はVMのネットワークが起動しない。
Bringing up interface eth0:  Device eth0 has different MAC address than expected, ignoring.
[FAILED]

# ifconfig eth0 | grep HWaddr | awk '{print $5}'

# ifconfig eth0 | grep HWaddr | perl -ane 'print pop(@F), "\n"'
