FilterScheduler is the only scheduler driver that properly integrated with placement api so this patch changes the functional test environment to use the FilterScheduler instead of the ChanceScheduler. The amount of vcpu the SmallFakeDriver reports need to be bumped to 2 as during resize to same host the filter scheduler doubles the allocation on the host. Simply relying on the 16.0 default allocation ratio does not work as the max_unit of the vcpu does not use the allocation ratio to avoid that a single server overallocates the cpu. The only change in unit test is test_create_instance_with_oversubscribed_cpu which also loads the SmallFakeDriver and asserts available resources on it.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
