Hi Tristan,

   My main concern with our current status is that it's difficult for a
user to configure the serial ports.  On my system, I end up passing
console=ttyS8 xencons=ttyS8 to the dom0 kernel to get things working
correctly.  The 8 value is somewhat arbitrary and works because our -xen
kernel happens to only claim the first 8 ttyS devices.  How are we
supposed to document bizarre settings like that?  Is this an area where
we really want to have a whole chapter of differences versus x86 in the
user documentation?

   I also don't agree that the Xen keytable is only for developers.  It
may be that this is an important debugging tool and therefore required
to be able to support a real customer.  I'd rather see this feature on
by default so it's there for in-the-field debugging later, and so that
the xen/ia64 community uses it and makes sure it works.  Thanks,

        Alex
