Great. It's all available to you as part of the distro.

You have to understand that there are two parts to LVS - the kernel
modules (which actually do the work) and the userspace parts (which
allow you to configure it). The kernel modules get updated as and when
necessary - you'd have to look at the changelog at kernel.org to see
when that's happened, but the most recent changeset was put into 2.6.24
in November 2007.

You already have the kernel modules - Fedora includes them. You need to
install ipvsadm using Yum:
yum install ipvsadm
That gets you a basic set of tools with which you can make a lot of
stuff happen. If you want high availability, health checking, monitoring
and so on then you need some other tools to do that for you:
keepalived
ldirectord
heartbeat
to name but three.
