I can even set the arp_announce and arp_ignore remotely so now 
everything is in just two config files:
keepalived.conf and ip_localhost

I have found that when needing to recycle keepalived that the order of 
starting and stopping seems to matter. The most reliable way I have 
found is:
service keepalived stop (backup director)
service keepalived stop (master director)
service keepalived start (master director)
service keepalived start (backup director)

otherwise LVS seems to get confused and there ends up being no entries 
in the LVS table. Maybe this is related to how I am configuring 
keepalived but I wouldn't think setting the VIP on the real servers 
would affect the LVS table.
