The FakeVirt driver shouldn't need custom scheduling options, so it run
instead of a real virt driver for testing purposes. This simplifies the
use case where someone wants to run the FakeVirt driver along side a
real driver so someone can test there cloud application without wasting
real instances.
Since the FakeVirt driver should look like it has near infinite resources,
turn on Core, Ram and Disk filters to make sure the drive works with them
enabled.
