Hmm - you got a few things wrong int here, didn't you? ;-)

Try using the /etc/xen/xmexample.hvm as a base, instead of one of the
paravirtual ones.. 

So, you want kernel to have ".../hvmloader", as that's the "application"
that loads the BIOS and gets things started. 

Is your CDROM really /dev/hda?

Here's a simple "boot from CDROM" config file:

import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 1024
name = "CDROM-boot"
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/root/disk.img,ioemu:hda,w' ]
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
cdrom='/root/isoguest.iso'
boot='d'
sdl=0
vnc=1
vncviewer=1
serial='pty'
ne2000=0

I hope this helps.
