Bulk create of VMs with default security group fails due to high load of openvswitch
Issue
-
With the deployment 'nova + neutron + openvswitch', when we bulk create about 500 VM with a default security group, the CPU usage of neutron-server and openvswitch agent is very high, especially the CPU usage of openvswitch agent will be 100%, this will cause creating VMs failed.

When creating a stack that deploys 60 instances with 8 nics, most of the instances are created with no ip addresses. Steps to reproduced via OpenStack :
1. create 8 networks
2. create single instance with 8 nics --> instance is up and running and all ip addresses are exist
3. create 60 instances with 8 nics using heat file - stack
all instances are running but most of them without ip addresses
result :
tag was not created in "ovs-vsctl show" after creating an Instance
