Yes, using a file-backed image might be the easiest way. But the images 
from jailtime.org seem to be for Xen2 only. And they come without a 
kernel (and modules)

Apart from that you need a configuration file to start the Linux DomU. 
This is from my config file (/usr/pkg/etc/xen/ubuntu) with Xen3 and 
NetBSD 4.0_BETA as Dom0):

	kernel = "/vmlinuz-2.6.16.13-xen"
	memory = 300
	name = "ubuntu"
	vif = [ 'mac=00:16:00:00:00:01, bridge=bridge0' ]
	disk = [ 'file:/xen/Ubuntu/ubuntu.img,0x308,w' ]
	root = "/dev/hda8 ro"
