I'm trying to setup some Xen stuff, and made 4 images, exactly the same, based on the Ubuntu hardy 64 bit system I'm running everything on.
I literally made the images with a bash loop, and they are all exactly the same, named xen{1,2,3,4}.
1, 2, and 3 start just fine, but 4 hangs on waiting for root file system.

Just a stab in the dark, but have you ran out of loop devices? run "cat /proc/diskstats" to see how many loop devices your kernel can use.
