Does "console=hvc0 earlyprintk=xen" on the kernel command line give any
clue about how far it gets before crashing?
I built a kernel using your .config here, but I can't reproduce the
problem. It makes it all the way to trying to start init (failed at
that point because I didn't create an initrd with the xvd module to
mount /).
Console is already hvc0, but earlyprintk gets us:

That's it.

What happens if you give the domain less memory?
