The easiest and most trivial way to resolve this is a requirement of the LVS-DR method - to have the VIP(s) bound to loopback interfaces as /32 addresses (as interface aliases, or using "ip address add $VIP/32 dev lo"). If they then become active on an ethernet (or other) interface with a longer netmask, the nameserver daemon is already listening on that address so service continues with no interruption. When that interface goes away (on IP failover, for example) the address remains on loopback so the service continues once more.
