New deployed system allows CPU overcommit when forcing host node
Issue
- It is possible to overcommit CPU's on the target host, even with CPU overcommit disabled.
- Raising later new instances without specifying the host, doesn't allow CPU overcommit
- As a third step, launching again instances with a target host fails with corefilter reporting the core amount cannot be satisfied
Environment
- Red Hat OpenStack Platform 7 (Kilo)
