Re: A question about Dom0.
Just to add to the discussion, there is also the possiility of runing Xen without the dom0.
Atenciosamente, Charles Ferreira Gonçalves
Thank you Andy.
Thus, Xen Hypervisor runs directly on the hardware without any OS? If yes, after it, the Dom0 (an Operating System) run as a VM by Xen Hypervisor?

The Xen hypervisor kernel image is usually stored inside what is the
dom0's /boot directory but it is booted directly by the
hardware/firmware before dom0 exists, because dom0 is just another
VM that the hypervisor then runs.
The image also might not be stored inside the dom0 filesystem as it
might be booted over the network or whatever.
Also a full Xen install is not functional without its management
tools, of which the dom0 operating system and several software
packages on it are a part.
So whether you consider Xen to be installed "on" the dom0 is really
a question of perspective. You aren't asking specific enough
questions to get a simple short answer.
Cheers,
Andy
