On RHEL-5 the qemu-kvm binary is located in /usr/libexec. To reduce confusion for people trying to run upstream libvirt on RHEL-5 machines, make the qemu driver look in /usr/libexec for the qemu-kvm binary. To make this work, I modified virFindFileInPath to handle an absolute path correctly. I also ran into an issue where NULL was sometimes being passed for the file parameter to virFindFileInPath; it didn't crash prior to this patch since it was building paths like /usr/bin/(null). This is non-standard behavior, though, so I added a NULL check at the beginning. Signed-off-by: Chris Lalancette <clalance@redhat.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
