Since it's likely to be slow on the list now, I'll give this a stab, tho' I'll 
warn you I haven't actually done this myself. However, some things stand out:

The reason Plan A didn't work is you can't load the xen hypervisor (xen.gz) 
inside a domu. Try deleting the 'kernel /xen.gz...' line and 
change 'module /vmlinuz...' to 'kernel /vmlinuz...'. I personally would use 
the original fc8 /initrd-2.6.21-2952.fc8xen.img. At a minimum, a custom 
initrd also has to have '--preload=xennet'.

The basic problem with your other plans is it looks like the hvm install 
created a whole disk (hda) with an fc8 partition on it in, presumably hda1.
I don't know if specifying hda in the disk= parm and root='hda1 ro' will work 
in Plan B, but it's closer to what you mean.

If you get something to work, presumably with the help of someone wiser than 
me ;-), you will also want to eventually replace hda* with xvda*. Good luck, 
and keep us posted.
