Description Benjamin Schmaus 2016-06-14 00:32:02 UTC 
Description of problem:

The SameHostFilter should pass only if the host is executing an instance
from the set of uuids passed in the scheduler hint 'same_host'. However,
it passes also if the host does not have any instance.

Version-Release number of selected component (if applicable):7.0/7.3


How reproducible:
100%

Steps to Reproduce:
1. See Private Comments Below
2.
3.

Actual results: Compute hosts that match hint key and hosts with 0 instances on them are used.


Expected results:  Only hosts passed as hint key should be used.
