Thank you Nico for your tip.

As per your advice I enabled the support for the CPU and now I am able to
use full Virtualization.

I have two more question that I would appreciate your advice:

1) Is there any performance differences between para and full
virtualization ?
2) What is better to create the virtual machine as a separate partition or
as a file ?


Yes, para-virtualization is noticeably faster than full virtualization. And for performance and management reasons, I recommend using LVM based partitions, not files. But if your system is already built and configured, that's not always feasible.
