This change is included in previous xeno patch made by John and me, for
bringing multiple domains back to the world. But seems Dan hasn't put it
into the xenlinux repository. Dan?

I'm not sure whether it's clean to do that, but you may copy .hgtags.d
from another repository if both have the same parent. I usually have one
copy cloned from xen-ia64-unstable.hg, and with another working copy
child of the former. When working copy failed like above reason, I can
retrieve from another one.

Currently vga console is disabled for xen0, to accommodate requirement
from xenU. xenU needs to register xen console as default tty, and thus
need disable CONFIG_VT. However in current stage, there's no individual
.config file for xen0 and xenU. So one xenlinux compiled out will be
used as both xen0 and xenU. If you want to enable vga console for xen0,
you have to compile twice by editing driver/char/Kconfig:
config VT
        bool "Virtual terminal" if EMBEDDED
        select INPUT
      >>default n if !VIOCONS (for xenU)
      >>default y if !VIOCONS (for xen0)

Unfortunatly, it

Now we're in process of merging non-vti and vti code, and then sometimes
you may see instability. We're also looking at it now. ;-)

Good news.
