Tested in a LAN with the following setup:
Host1 running MaxScale + keepalived + backends
Host2 running MaxScale + keepalived
Host3 running an sql client

With the keepalived configured (correct network interface, virtual IP within LAN address space) and running, the Host3 will connect (using the VIP) to the MaxScale with the highest priority keepalived running. If then the highest priority machine goes down (or just the keepalived service on it stops), the second (in priority) MaxScale takes over. Any existing connections will break.

Closing for now. A test has been performed, blog post written. May still require a real regression test but that requires changes in test framework.
