libvirt users - Dec 2013 - is qemu-kvm really searched for in /usr/bin for KVM?

reading KVM/QEMU hypervisor driver page here:

http://libvirt.org/drvqemu.html

and one reads, "KVM hypervisor: The driver will probe /usr/bin
for the presence of qemu-kvm ...".  on my RHEL 6.5 system,
qemu-kvm is in /usr/libexec, not /usr/bin. am i misreading
something?

That's expected behaviour: on RHEL and its derivatives,
the qemu-kvm binary is located in /usr/libexec

If you print the contents of your guest XML:

  $ virsh dumpxml vm | grep emulator

you'd notice the <emulator> attribute reflects /usr/libexec location.

If you'd like to propose a doc patch to mention that the probe covers
several common installation directories, rather than just /usr/bin, that
would be nice.

   if someone wants to tackle that, i'm kind of in the middle of
working my way through one of the other RHEL manuals at the moment,
and my brain is melting down.
