А где UP?

/sbin/ifup lo

А вообще в /etc/sysconfig/network-scripts/ifcfg-lo должно быть:

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

И запустить "chkconfig network on".
