Hi Todd,
Thanks for the link, it was very enlightening.
I had noticed the ''sparse'' directories were missing, and
wondered if
that implied that the upstream kernel now had the xen patches and
drivers included. It seems that isn''t the case.
Since Mercurial seems to be the default (and only) way to get the
patched kernel tree now, it seems bizarre that the Xen 3.2 README does
not document the command needed to fetch it.
I now have Xen 3.2 booting the 2.6.18-xen kernel, but ran into further
problems mounting root. I built an initrd, but the ide driver does not
seem to be finding the drive/controller. Unfortunately I don''t know is
this issue is specific to the hardware I''m using, or if it is a problem
with the xen/kernel/initrd configuration.
