I'm trying to configure two web servers for a load balancing server. The load balancing aspect works fine (it sees both server, kills 'em if it needs to, and seems to direct traffic fine). The only issue is with the servers looping:

/etc/sysconfig/network-scripts/ifcfg-lo:0

DEVICE=lo:0
IPADDR=<Virtual IP>
NETMASK=255.255.255.255
ONBOOT=yes
NAME=loopback

Everytime I try a "service network restart" I get a SIOCADDRT: No such process when loading the loopback interface.

Anyone have an idea what's causing this?
