See below ... I REALLY appreciate your help.  This was supposed to be a
simple migration from VirtualBox to Xen and now I'm caught in this quagmire

sorry for making this rich text but if I don't gmail will reformat it into
garbage ...

Disk /dev/xvda: 33418 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
