The most obvious problem (well to me that is) would be that you're running an 
amd64 dom0 and the domu kernel is not i386PAE or amd64. I'm not sure if this 
is documented but it is required.

I was going to say that balloon error is pretty typical, but looking on my 
system, it appears I no longer receive that error (it's not logged at least). 
I don't think it will prevent a domu from booting however.
