Frank,

I hadn't thought about SELinux, but I'll check on that.  I'm assuming
that the firewall isn't a problem, since I captured the packets on the
backup director.  But I'll test both of those, and report back.

All the communication between servers (both keepalived's VRRP, and the
IPVS connection sync) is going over Ethernet.  Since this is a test
environment, both directors (and the realserver) are actually VMWare
Virtual Machines.
