Yes, this is what I think so but I remember I tried this on centos (yum install xen-hypervisor) and added a new entry in grub.list

Do you have any  recommended link or books to learn more about it ?

Because of the limited capability with vbox, I tried to install xen Dom0 on my running linux (ubuntu 12.04 LTS), like Simion option based on this link: https://help.ubuntu.com/community/Xen . the dom0 was installed but no dual boot was shown at the start up to choose.

Any guess ?

If you run
'xm list' and 'xm info' you back something?
I think you are confused that is dual-boot.
For a dual boot, you need two SS.OO installed on the PC.
A 'apt-get install xen-hypervisor-amd64' does not make you a dual boot, just install a program. at most you should have the option to start the "common kernel" and "xen kernel."
