Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.   [FAILED]

原来UDEV这里把克隆前的MAC当成了当前虚拟机的eth0 MAC，而重新生成的08:00:27:32:66:63是eth1的MAC。

解决这个问题，只要删除旧的UDEV配置，修改为：
[root@Oracle ~]# cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
