I already have it working like that, although I omitted the syncid parameter (seems to not being needed according to some mail posts, don't have the link at hand) and specified an alternative broadcast interface (the cluster interconnect). In Pacemaker I have a group that manages de floating IP (IPAddr2+lvs_support) and ldirectord. The real servers have the "LVS ARP ignore" magic activated and the real IP on the loopback.
