New deployed system allows CPU overcommit when forcing host node

Solution In Progress - Updated -

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)
