Thanks a ton Michal for the reply. I tried your suggestion but a message popped out when was trying to save the xml file which said: "Editing of already existing domain is not supported"... :(
Why I want this is because the node which is getting created is creating empty vmdk image and if I try to boot with it, it says No Operating System found, which is quite valid. I want to attach my vmdk which has the OS in it.

I am just wondering how others are creating VMs and using it with libvirt...!! 

Is there any suggestion how I can boot my node?

Unfortunately, this piece of functionality is not implemented yet.
However, if you want to do a cold plug (that is disk will be visible at
next start of the domain), you can 'virsh edit $dom' and write the
appropriate XML snippet by hand.


P.S.: Patches are welcome :)
