I was messing around with KVM in CentOS 6.3 when I noticed I was having problems with the IP address of my principle network connection (eth0). I backed out my bridge and restored the network-script file for eth0 but the IP address still goes missing after reboot. At this point I have to return to the console and restart the "network" service. The address will then be restored but only until the next boot. I have turned off NetworkManager but this does not seem to help. The ifcfg is below:


Any ideas?

Have you checked: /var/log/dmesg, /var/log/messages, or /var/log/daemon.log for the relevant information? If so please post it. – Karlson Sep 26 '12 at 13:02
What's the * before DEVICE, was it a typo? – warl0ck Sep 29 '12 at 8:27

At this point I have to return to the console and restart the "network" service.

The reason is clear through your description, your network service wasn't started automatically, so do a chkconfig --level 2345 network on will fix your problem.

P.S: I just saw a * before the DEVICE, so that could be a problem as well (if it's not a typo)

...or something is messing with the network stack on boot, such as a DHCP agent. – Patrick Dec 9 '13 at 4:15
