This patch is good, but the server/Makefile.in needs to use pkg-config
--cflags / --libs glib-2.0 rather than static definitions.  I have
included an updated patch.

Otherwise, I do like this patch quite a lot.

The only question I had is why there needs to be an external STONITH
plugin; I was of the impression that fence_virt and fence_xvm work out
of the box with Pacemaker 1.1.x.  That doesn't affect this particular
patch, as far as I can tell (it looks like just a glue wrapper between
pacemaker and fence_virt itself).
