I can provide single line command for end users...
In case of virt-install can i provide xml for domain while import ?
For example i can generate xml with minimal memory/devices needs to be
present..

I don't think `virt-install` itself can import an XML (although, it can
print a XML via the '--print-xml' option, look up the man page for
this). If the users have the disk images in the right place, you can
provide the guest XML, and the users can define it using:

    $ sudo virsh define uservm.xml
