shadow_memory patch

What basically did was include the "shadow_memory" parameter in the HVM config
file with 8MB by default. This fixes the problem alone. Now, I went further and
created a function to grow this memory as needed.

The stipulation is that there should be 2KB of memory for every one MB of RAM
assigned to the guest domain, plus a few MB per vcpu ( ~2MB).

The 8MB of shadow memory is more than enough for xmtest when concerning RAM.
The my function grows this shadow memory if we have more than 3 vcpus. This is
just a safety precaution.
