Is it possible? For LVS you have to deal with something called the ARP problem (viz., the realservers should not respond to ARP requests for the hardware address associated with the virtual IP). This is solved with some sysctl stuff for kernel 2.2.x and for 2.4.26+, but of course CentOS 3 is 2.4.21. There's a kernel module "noarp" that's suppoed to work for all 2.4.x kernels but I can't get its configure to work properly. Does anyone have any experience with this module? Is there an RPM somewhere?

The configure script tries to identify the directory in which to install the module, and gets confused because there are multiple kernels (both UP and SMP) installed on the system. The result of this confusion is a borked sed script (newlines where they should not be) which trashes the configure process.
