If you're just doing dev changes, it is best not to install it into
your main system. Instead just build and run directly from the source
tree. 

eg, what I normally do is

   ./autogen.sh --enable-compile-warnings=error --prefix=/usr --localstatedir=/var --sysconfdir=/etc 
   make

And *not*  make install.  

Then as root just stop the normal libvirtd daemon that comes with your
distro, and run the one you just compiled manually, eg

  $ su - root
  # /etc/init.d/libvirtd stop
  # /home/berrange/work/libvirt/qemud/libvirtd

And likewise, use the 'virsh' binary directly from the source tree

  $ cd $HOME/work/libvirt/src
  $ ./virsh
