Network connection issues on Oracle Linux 6.5 VM

I took a snapshot of this VM(Oracle Linux 6.5) last month when all the installation was done. The nework connections was working when I took the snapshot. Now when I rolled it back to that snapshot, it says no network connections. All the network configuration is still there.
By the way, it shows IP Address: fe80::250::56ff:Fead:xxxx now from the vSphere client guest view.

Restart VMTools. If that doesn't work then go in and disable IPv6.
Did you install the GUI with Linux or only CLI?

In the GUI, you will see the network connection on the top right. Right click on that and choose "Edit Connections..."
From there you will see a Wired connection "Auth eth0", click on that and click on the edit button. A window will appear and you will see an IPv6 setting tab, click there and change the method (drop down box) to "Ignore".

I would then reboot VM and try again.

It stated "Ignore" in IPv6 settings. I just ran VMWare updates (current VM version: vmx-10)and reboot the guest but still same issue.

still saying "No network connection"
James HIT DirectorCommented:
In the setting of the VM itself, it the vNIC set to be connected and connect on power on.
Do you have any network card installed?
By default oracle linux comes up with network down. You need to edit /etc/sysconfig/network-scripts/ifcfg-eth0 and change ONBOOT to yes, Then network will come up (service network restart // can save a reboot)
