Hm, there is nothing here that looks wrong, per say. I would suggest
you do: dom0_mem=max:1G instead of dom0_mem=1G (otherwise you end up
having dom0 contain pages for the full 13GB).

Besides that, can you do redo this with on Linux command line be:

'earlyprintk=xen console=hvc0 debug memblock=debug loglevel=8 initcall_debug"

And add on the Xen line: "sync_console".

Hopefully that will provide some idea of why this is not working right.
