Subject: [PATCH] Update KVM to simulate up to 4 CPUs.

This allows KVM stage to run significantly faster. On
my machine, with this change I was able to run the pre-flight
queue VM update tests in ~369 seconds, compared to the normal
time of >1000 seconds.

BUG=chromium-os:23112, chromium-os:22784
TEST=Verify speed increase, trybot runs.
