I have the same network problem with Red Hat 7.2.

I just installed 7.2 on virtual machine hosted by ESX 5,5, configured network, it worked fine. but after reboot, the VM lost public network connection. I have to logon console then run following command to enable network connection:

service network restart.

What's the root cause? how to fix it?

The following are output of nmcli:

nmcli dev status
