From 57e5c3c2ae83fdddeecc9208b3485a47065a0eb5 Mon Sep 17 00:00:00 2001
From: "Daniel P. Berrange" <berrange@redhat.com>

Subject: [PATCH] Use virFileFindResource to locate libvirtd daemon

Make the remote driver use virFileFindResource to find the
libvirt daemon path, so that it executes the in-builddir
daemon if run from source tree.
