Public bug reported:

Description
===========

I'm running devstack Mitaka with networking-ovs-dpdk. I set the cpu model to Haswell in the flavor, but the guest is created with the default qemu cpu model:
model name      : QEMU Virtual CPU version 2.3.0

It worked when I was running on Kilo.

Steps to reproduce
==================

Simply run devstack mitaka, then:
nova flavor-create CIRROS-PERF auto 1024 80 6
openstack flavor set CIRROS-PERF --property hw:cpu_model=Haswell
nova --os-tenant-name admin boot --poll --image cirros-0.3.4-x86_64-uec --flavor CIRROS-PERF --nic net-id=d34b5e4c-b39b-4787-8e8d-ebd9464932c5 --nic net-id=7556233d-a09d-421a-bace-59500971539a demo-vm-cirros-1
