You mean a live CD which can be booted as a Xen guest? Or a live CD which contains (eg) a Xen hypervisor?

I haven't tried it for Xen (only for QEMU/KVM where it definitely works), but you should just be able to boot the CDROM directly.
Try creating XML configuration following this example:
http://libvirt.org/format.html#Fully1
and set the cdrom source file to point to the ISO file. You can leave out the hard disk, or point it at an empty file or existing image depending on what you want. Then do:
virsh define my.xml virsh start fv0
(where fv0 is whatever you chose as the domain name within the XML file).

Try creating XML configuration following this example:
You can do this more directly with virt-install
[quote src="virt-install(1)"] Run a Live CD image under Xen fullyvirt, in diskless environment
# virt-install \ --hvm \ --name demo \ --ram 500 \ --nodisk \ --livecd \ --vnc \ --cdrom /root/fedora7live.iso [/quote]

Thanks for the reply, does booting a live CD requires hardware support in Xen?
My processor is pentium 2.8GHz

In Xen yes:
# virt-install \ --hvm \
However QEMU will happily boot a CD-ROM ISO without hardware support.

That's not enough to tell. Have a look at /proc/cpuinfo, flags, which should contain 'vmx' if hardware-assisted fullvirt is supported. (For Intel you may also need to enable it in the BIOS).
