[SOLVED] Centos 7 network problem in os

cajunchief · 08-20-2014, 01:37 PM

TO ALL,

I'm not sure if this is the CORRECT or BEST place to put this question but here it is:

I upgraded from Centos 6.5 to Centos 7. I was hoping to get KVM up on Centos 7 however
during the upgrade Centos 7 gave me a device code of "eno1" for my eth0 device.

Why is this and how do I fix it if any of you have an idea?

Merci,

cajunchief

Did your upgrade break off? Does your eth0 HW need some custom module? Did you save the upgrade log? If so post its contents.

Hi:

It could be something lacking in udev but I'm not 100% sure-
Sorry I'm not good with kernel based virtual machine but I'm sure others here are.

Are you getting an error that says "device not found"?

The network adapter might not be eth0 anymore. What ifcfg-??? files are in /etc/sysconfig/network-scripts now? Also, what adapters is ifconfig reporting?

@-travisdh1:

Would running ifconfig or ifconfig -a help?

If it helps here are all the files on my Centos 7 machine in the /etc/sysconfig/network-scripts.
Maybe this could give you an idea of what OP has--

From the directory listing it looks like the network adapter is called WIN_5516. Try

Code:

ifup WIN_5516

If that doesn't work then the output of ifconfig should help (run it from a terminal window as root.)

That network adapter was on my machine.
We need the output from OP's machine--

When you have the time please post a screenshot of your /etc/sysconfig/network-scripts directory.
Or post a list of all of your files in the said directory.

IF you have trouble with that than please post the output of:
ifconfig
