Hi Alessandro, If the switchports for storage are in access mode then indeed you can't present another VLAN there. You might be able to create a new logical interface on Xen in the same VLAN with the new IP range, but that's not something I've tried before (works fine on ESX and KVM though).
I'd always recommend to use Trunked ports everywhere, keeping your L2 fabric as simple as possible and all the intelligence down in the hypervisor and not in the switch, this gives you much more flexibility. But of course, other ways of setting up are always valid, that's just my preferred one based on experience.
