Comment 6 for bug 1566358

I tested case when there both types of computes (w/ and w/o DPDK) in cluster and instance connectivity test still fails, because it's spawned on compute node with enabled DPDK but default flavor 'm1.micro':

AssertionError: Failed 1 OSTF tests; should fail 0 tests. Names of failed tests:
  - Check network connectivity from instance via floating IP (failure) Instance is not reachable by IP. Please refer to OpenStack logs for more details.

>So mechanism of #2 should be implemented with new filters (AggregateInstanceExtraSpecsFilter,NUMATopologyFilter). This filters are added to nova.conf when we enable HP

Using Nova availability zones or some filtering mechanism to prevent incorrect instance scheduling (with default flavors) sounds like a solution for me.
