It didn't start anything that listens on any port on the Dom0 machine. I
added "vncviewer=1" and that started a vncviewer but I'm not clear how am I
supposed to connect to it.

Anyway, from more googl'ing I was reminded about "xm console" and attached
below is the output from when I invoke it - it looks like the guest kernel
doesn't find some important devices and then just sits there without
completing the boot process.

>From Googl'ing the error it sounds like the initrd (or the /lib/modules
directory on the Xen Guest's filesystem?) is missing some xen-related device
modules but installing
kernel-xen-2.6.20-2925.9.fc7.x86_64.rpm<http://mirror.bytemark.co.uk/fedora/linux/releases/7/Fedora/x86_64/os/Fedora/kernel-xen-2.6.20-2925.9.fc7.x86_64.rpm>and
trying to use the kernel and initrd image from there just causes the
guest to boot in a loop too fast and causing Xen to just destroy it.

What could be the problem now?

Here is my current config file:

kernel = '/boot/fc7-xen-vmlinuz'
ramdisk = '/boot/fc7-xen-initrd.img'
memory = 256
name = 'fc7-01'
root = '/dev/hda ro'
vif = ['type=ioemu, bridge=xenbr0']
disk = ['phy:/dev/xen/fc7-01,ioemu:hda,w']
cdrom = 'file://root/iso/fc7/i386/boot.iso'
device_model='/usr/lib/xen-3.0.3-1/bin/qemu-dm'
boot='d'

Thanks,
