unable to create Mac OS X virtual machine

I am trying to install a Mac OS 10.8 as a virtual machine using 'Install Mountain Lion using Recovery Partition' option in Parallels Wizard, but the installation hangs at grey screen with the Apple logo and the circle progress is shown, where the circling of the progress indicator has stopped/frozen.


If I copy working virtual machine that has been created on another Mac to the Macmini5,2 >> the virtual machine boots for some few seconds, then halt with a black screen.
