I believe, you have to enable Xen Privileged Domain Support in JF kernel
to load it under Xen 3.4.X Hypervisor.
Otherwise, Dom0 won't be loaded.

I somehow did not search deeply enough - there was a related discussion
on xen-devel mailing list. It is a little hidden in the "Vt-d not
working with 3.4.1" thread. There does not seem to be a final "i got it"
post though - I'll try some different solutions proposed there.
