RE: [Xen-ia64-devel] config files and dom0/domU

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

No, it doesn't work.  I think since XEN_PRIVILEGED_GUEST
depends on XEN (default yes), it always gets turned back
on when running make oldconfig.  If you remove the
XEN_PRIVILEGED_GUEST from arch/ia64/Kconfig but set it =y
in the config file,
1) it disappears from .config file after make oldconfig
   (which is bad because it is needed for dom0), and
2) CONFIG_VT doesn't seem to get turned on anyway!

I am bewildered...
