[PATCH v2 10/10] tests/vm: add 512MB extra memory per core

[John Snow]

If you try to run a 16 or 32 threaded test, you're going to run out of
memory very quickly with qom-test and a few others. Bump the memory
limit to try to scale with larger-core machines.

Add this magic in early to the configuration process so that the
config file, if provided, can still override it.
