Hello Daniel, Thanks for you help. I installed xen-devel rpms and manage to make, make check and make install libvirt. Then I tried to test it by trying the simple python script given on the libvirt site. <a href="http://libvirt.org/python.html">http://libvirt.org/python.html</a> It failed and complained about not finding libvirt module. I guess Python was unable to locate it. I thought "make install" for libvirt would have taken care of it, but seems not to. How could I make Python aware of my libvirt module? Do I need to create an envoirnmental variable or else? ==== Error: Traceback (most recent call last): File "testLibvirt.py", line 1, in ? import libvirt ImportError: No module named libvirt ==== Any help would be much appreciated!

Ask your sysadmin to install them (or whoever maintains your SL4 version). I already answered something similar last week, reposting the same bits won't help. Check with the system administrator to get the development files for Xen installed on your system. That system is specific to CERN, apparently, that's why you should ask for support locally ! We can't debug that !
