Why do you have compile ipvsadm > for specific kernel versions? ipvsadm uses get/set-sockopts on a raw socket to pass commands and structs (as defined in include/net/ip_vs.h) to the kernel. So the passed structs have to match exactly between userspace and kernel. The kernel ip_vs.h also includes a version number that is used to verify that ipvsadm matches your kernel version.
