As part of a test lab setup, I recently installed Oracle Linux 6.9 32-bit (V860938-01.iso). I chose Desktop installation. The system boots fine - the Unbreakable Enterprise Kernel (2.6.39-400.298.6.el6uek.i686). However, it refused to start my local network:
[root@myhost ~]# ifup eth0
Error: No suitable device found: no device found for connection 'System eth0'.
Here are the contents of my network files:
[root@myhost ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=myhost.mydomain.com
GATEWAY=10.177.186.1
[root@myhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
PEERDNS=yes
PEERROUTES=yes
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
However, the ifconfig -a lists only the loopback interface:
[root@myhost ~]# ifconfig -a
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

RX bytes:38152 (37.2 KiB) TX bytes:38152 (37.2 KiB)
What I have is an Intel I219-LM ethernet card:
[root@myhost ~]# lspci | fgrep -i ether
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-LM
According to a few blogs I went through, the e1000e driver should work. I checked the lsmod, and the driver was not initially loaded. I modprobe'd the driver. This time the driver is listed in lsmod, but not that it made any difference:
[root@myhost ~]# lsmod | fgrep e1000e
[root@myhost ~]#
[root@myhost ~]# modprobe e1000e
[root@myhost ~]# lsmod | fgrep e1000e
e1000e 217853 0
[root@myhost ~]# ifup eth0
Error: No suitable device found: no device found for connection 'System eth0'.
[root@myhost ~]# nm-tool
NetworkManager Tool
State: disconnected
Interestingly, if I boot the Redhat Compatible Kernel (2.6.32-696.23.1.el6.i686), the network is fine. Unfortunately I run into several other issues (system hangs and stuff) on that Kernel.
Any tips you can offer is greatly appreciated!!
