Ok.. I see that a 500 Gb  disk is allotted  to the VM instance but it
doesn't show anything beyond 20 Gigs.  This instance along with many others
booted up with metadata ,but ( I just recalled that my VMs dont get
metadata successfully during very first boot and this may be the cause of
this nonsense. what I have to do is I have to reboot the vm twice to make
it ready for the OpenStack Env. like correct interfaces, hostname, etc. )

Let me get back to you guys with updates on a new VM ...
