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. 2.6.22.14-72.fc6 ...
