You can use any kernel as dom0 for Xen 4.0, so long as that kernel includes
dom0 support. So that could be 2.6.18, or 2.6.27 from XCI project, or
Jeremy's pv_ops git tree, or some distro kernel. The kernel built by default
by the Xen 4.0 build system will be Jeremy's pv_ops tree, but that doesn't
mean you *have* to use it.
