I'm using Xen 4.0.3 and linux 2.6.32.46 for dom0 and domU as well. From
xenstore-ls, I could see the numbers you mentioned 51713 and 51714 for my
guest, but the log says that the devices for the numbers are not detected as
follows:
*This is from console after I execute "sudo xm create -c <config>":*

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/xvda1 does not exist. Dropping to a shell!
