Due to ongoing issue with virsh compiled against libvirt 0.7.5 when working with Xen 4.0 Hypervisor. I attempted to downgrade libvirt and related stuff to Ubuntu Karmic’s ( well tested version with Xen). Proceed as follows :-
1.Edit /etc/apt/sources.list
Replace:
deb http://us.archive.ubuntu.com/ubuntu/ lucid main restricted

This posting is actually responding recent entry in Martin's Blog
