I'm looking into adding High Availability for haproxy Virtual IP.
Let's say I have 4 HNs each with a VE running Centos 6 and haproxy for load balancing.
My research seems to indicate I might need to install and use Keepalived to make the haproxy VEs HA.
How do I best do this? My VEs all currently use venet0 for network access. Do I install Keepalived on each HN? Should the VIP be added to each VE so when Keepalived changes eth0 to route this IP to the VE on the HN?
I'm a bit confused as to how all this works. There is a Wiki page on the subject, but it seems half written doesn't go into how this all could work (just says to add NET_ADMIN capability to VE and add some kernel modules to the HN).
