CentOS 7.9.2009 Minimal Install - No Network Devices Available [SOLVED]

Post by CaveDann » 2021/03/25 14:57:45

I'm using the CentOS-7-x86_64-Minimal-2009.iso for a graphical install. Clicking the Network and Host Name menu says that there are "No network devices available", i.e. they aren't being detected at the point of install.

I ignored the message and continued the install so that I could boot and investigate the issue with lspci.

Code: Select all

user.localhost > lspci -nn | egrep -i 'network|ethernet'
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (11) I219-LM [8086:0d4c]
I thought that the I219-LM was covered by the e1000e driver that would be in the ISO, but was I mistaken?

Has anyone else encountered similar recently?

Cheers,
CD

Edit: I wasn't sure if this belonged in Software or Hardware, so I opted for General. Sorry.

There seem to be several I219-LM. Mine says

Code: Select all

00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (2) I219-LM [8086:15b7] (rev 31)
and is supported by the 7.9 e1000e driver. Your [8086:0d4c] isn't.

You could try the e1000e driver from elrepo. They package a more recent version.

Hey Chemal,

Thanks for the response. I'm looking into the elrepo package now.

If it works in post, I'll probably look to try and get it onto a driver update disk so that I can use it during the initial installation.

Either way, I'll report back at some point to keep the record here going.

Cheers,
CD

Looks to be solved. First, I downloaded the kmod-e1000e package from ElRepo using yum.

Code: Select all

yum install --downloadonly kmod-e1000e
Then I copied it to a USB and provided it to the installation using the inst.dd flag.

Code: Select all

inst.dd=hd:sdc1:/kmod-e1000e-3.8.4-3.el7_9.elrepo.x86_64.rpm
Job's a good'un.

Cheers,
CD

Make sure you also install the elrepo-release package to add their repo. Then when a new version is required for a newer kernel, you will get that update at the same time as the kernel is installed and won't notice. If not it might stop working when the kernel is updated.
The future appears to be RHEL or Debian. I think I'm going Debian.

Hey Trevor,

I do normally install the elrepo-release package as part of my image, though I hadn't considered what you discuss here as a potential consequence of handling the driver the way I had.

Appreciate the warning.

Cheers,
CD
