floating IP - HA, kind of - how ?

Hi lejeczek,

What you are describing is what a load balancer provides. The load
balancing project for OpenStack is Octavia.
We have a cookbook that can guide you through setting up a load

We also gave an OpenStack summit presentation that is an introduction
to load balancing:

Load balancers provide the health monitoring and automatic redirection
of network traffic. They can also provide this failover much faster
than reconfiguring a floating IP.
