If you want to change the hash table size for ipvs
and you are compiling ipvs as a module then you only
need to recompile and reload the ipvs module for this
change to take effect.
You do need to patch and recompile the kernel in order
to use ipvs. However it is worth observing that this
is only so that a symbol that ipvs needs to be able to
hook into netfilter is registered. The kernel does not
know or care about the code in the ipvs modules when
it is compiled. Unless you are compiling ipvs straight
into the kernel.
Well, this is the case in the 2.4 kernels. In the 2.2
kernels ipvs did a lot more patching. I am not sure
