Will it be installed on existing OS or hardware?
What’s the difference between Hypervisor and virtualbox? I know I can install virtualbox on my windows xp and then install a couple of VMS with linux or windows on it.
thanks.

As explained in the fine wikipedia article, Xen is a bare-metal hypervisor, meaning it runs directly on the hardware.
However, as Xen itself has no user interface, it always requires at least one installed guest OS to work. There must be one OS guest that runs with special privileges (the so-called “dom0”). This dom0 is used to manage Xen, and so has a similar role to the host OS on a hosted hypervisor. So, while technically speaking Xen runs directly on your hardware, in practice you will still install an OS, then install Xen from inside the OS, just like for a hosted solution. However, you will then have to reboot into Xen (which will boot the dom0 OS).
Hypervisor is the general term, and both Xen and VirtualBox are implementations of hypervisors.
Yes, you can do the same with Xen (though support for Windows guests seems to be more limited than with VirtualBox).
