I don't know why you need to actually boot a paravirtulized guest from 
cdrom.  But If I have to go to rescue mode of a paravirtualized guest, I 
used to do something like the below one. The example is only applicable 
for RHEL/Fedora/Centos, I don't know how best this can be suited for 
other distros.
Download the images/xen/{vmlinuz, initrd.img} from the 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 = "rescue"

Comment out the line starting by "pygrub = ".

Boot the guest as usual and specify nfs/http/ftp repo as the rescue source.

It had worked very nicely for me. Is there any other requirements that 
compells you to boot a PV guest from cdrom except to go to rescue mode?
