When I do a ifconfig in centos 6.5 I only see the loopback lo interface. How can get eth0 interface back online. The centos system is a vm and was powered off for a while.

#dmesg | grep -i eth

this will show you available Ethernet interfaces.. then use

#ifup eth0

in case doesn't comes up then you need to create config file with basic parameter

/etc/sysconfig/network-scripts/ifcfg-eth0
device=eth0
onboot=yes
..
..
..

:wq

Thanks Sandy.
I ran the dmesg and it showed the interfaces. I tried ifup etho but a "configuration for eth0 not found" message. I then created the ifcfg-eth0 file and then when I tried ifup eth0 it states "Device does not seem to be present, delaying initialization." What should I try next?
