VM's failing to spawn with cpu_thread_policy as isolate in the flavor

Solution In Progress - Updated -

Issue

  • Whenever we are adding hw:cpu_thread_policy=isolate in the flavor properties, vms are not coming up inspite of having required number of cores.

  • Do we need to change any particular settings to make it work because irrespective of number of vcpus (even with count of 1) vm's are not coming up ?

Environment

  • Red Hat OpenStack Platform 16.1 (RHOSP)
