Hello Bobby, This may not be exactly what you want, but if you check out the IBM System z Test Report there is some material about Linux recovery scenarios. If you check out the section on making apache ha in the preparation section, it actually discusses a way to use heartbeat to float a resource across 2 vm instances. In fact the testing spanned 2 instances of Linux on vm, as well as an LPAR. Additionally it was cross CEC. The approach shown may be of more use generically as well.
I hope this helps. http://publibz.boulder.ibm.com/epubs/pdf/e0z1p150.pdf P.S. The material covered talks about 3 systems sharing the IP address, so a heartbeat style 1 cluster may be sufficient for your needs. Also the stuff works much better when everything is layer 2, but I am certainly no networking expert. P.P.S. I dont know how many on this list know about that test report but it also covered a 2 node configuration in the previous edition if I recall correctly. I hope you find it useful.
