Networking issue after upgrade to RHEL 7.2

Latest response

So, we recently upgraded a VM to RHEL 7.1 to 7.2

After rebooting the VM, I am not getting the public internet access automatically. I cannot connect to redhat.com or any other site.
I have to issue the command "systemctl restart network.service to get the access. Everything works fine till the next reboot.

When I check the status of "systemctl status network.service" after the reboot of the VM, its shows all the interface active.

Any suggestions what might be going on here? How can I make sure that I get the public access right after the reboot, without having to issue the restart network.service command.

Thanks

Hello

is the connection profile set to activate on boot? In nmcli this will be shown as connection.autoconnect: yes

Try:

nmcli dev status

Get you connection's device name and then try

nmcli con show <your device> | grep auto

Just a reminder, nmcli supports tab completion very well so it does not take long to learn.

Even I have similar issue I have updated rhel 7 to 7.4 via software update but after software update internet is not working even my firewall is disabled still. I am connected to my WiFi network still after pinging 8.8.8.8 it shows host not reachable please help

Note I am not using VM. Rhel is installed on my base machine

I have the same problem with Red Hat 7.2.

connection.autoconnect: yes

But every time after reboot, the VM can not get public network connection. I have to log on to Console then run:

service network restart

then it works fine.

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

The following are output of nmcli. looks normal. After run service network restart, network works fine, until next reboot. It's REHL 7.2. 3.10.0-327.el7.x86_64.

nmcli dev status
