It is not necessary to rebuild userspace, unless you want to use new 
features.

I suggest downloading qemu-kvm-0.12.0-rc2.  All you need is a 
./configure; make; make install.

I doubt he meant kvm is not for production use.  Instead, the 
development snapshots are not meant for production use (as they do not 
receive updates, for example).  Instead, use the modules and userspace 
provided by your distribution, or the kvm-kmod and qemu-kvm packages.
