There are at least two reasons:
1)If I would like to upgrade the version of an existing installation
(if I'm using a redhat distro), I need to boot from cd and choose to
upgrade an existing installation.
This can be achieved by following the method that I described earlier. I
have not tested though.
Download the images/xen/{vmlinuz, initrd.img} from the new distro source
to /var/lib/xen/images.
Add the below lines to the guest configuration file.
kernel = "/var/lib/xen/images/vmlinuz"
ramdisk = "/var/lib/xen/images/initrd.img"
extra = "upgrade"
Comment out the line starting by "pygrub = ".
Boot the guest as usual and specify nfs/http/ftp repo as the rescue
source. Once the upgrade is completed, reverse the configuration file
to its old state.
2)If I want to test some live distro, I need to boot from cd.
This is not possible.

You can't boot a PV guest from CD, I'm afraid :-(
What are you trying to do? For installing the guest there are
various tools
(virt-manager / virt-install, rpmstrap, debootstrap and others)
that can help
you create a guest filesystem without needing a boot CD.
Cheers,
Mark
