I have RHEL5 and Xen  3.1.2 installed. This is installed through RHEL RPMS
using puppet.
For installation of collectd I just did yum install collectd. So its the
same as above.

So I see libvirt.so is not present in /usr/lib64/collectd and even
attempting to copy them from somewhere like /usr/lib64 to
/usr/lib64/collectd i.e. PluginDir does not work as it says -
MODULE_REGISTER is not defined so I understand collectd expects some funcs
which are OBVIOUSLY not there in default.

Another point is - since everything is installed with RPMS I am not sure if
COLLECTD expect source files for libvirt which to change/add funcs as the
way it requires e.g. MODULE_REGISTER func for libvirt in libvirt.so in
PLUGIN_DIR ?

Well as part of my work, I will have to get this working, So once am done
with my experiments I can contribute the patch.
