Bug description:
  From a patch https://review.openstack.org/#/c/459485/ which passed our XenServer CI, we can see there are some errors in nova http://dd6b71949550285df7dc-dda4e480e005aaa13ec303551d2d8155.r49.cf1.rackcdn.com/85/459485/4/check/dsvm-tempest-neutron-network/61927a4/logs/screen-n-cpu.txt.gz
  We need to figure out whether this is real problem or just configuration problem
