YESSSSSSSSSSSSS!
Actually it was compiled as module but it wasn't running.
Also the xen-gntalloc module is present but it is not running.
Now, simply modprobing the xen-gntdev module, the vm has started, and
the console is available!
Only one problem now: the guest machine doesn't get any IP when dhcp runs.

It was my mistake! I thought they were loop files too.
