It shouldn't do but I had some weird issues communicating between real
servers when this happened so I had to modify the IPAddr2 script to remove
the IP as there seems to be a bit of a regression with lvs_support=true
where it has to match the full IP and subnet to remove, but you need to
have the VIP as /32 on loopback and /24 on eth0
