Corosync

We will use corosync to create a virtual IP which is shared by two systems

apt-get install corosync

Add the local network and a multicast address to /etc/corosync/corosync.conf in the interface section

interface {
        bindnetaddr: 192.168.1.0 
        mcastaddr: 239.192.1.1
}

This has to be configured before haproxy configuration makes any sense, since haproxy should listen on the virtual ip. also we need to configure the dns name for the virtual ip first. so this depends on dns updates too.
