Devstack grizzly launched instance goes in the "Error" state -

the set floodlight controller , devstack running inside same vm on vmware workstation. referring link: floodlightcontroller install docs

so local file looks this: disable_service n-net enable_service q-svc enable_service q-dhcp enable_service quantum enable_service bigswitch_floodlight q_plugin=bigswitch_floodlight q_use_namespace=false nova_use_quantum_api=v2 scheduler=nova.scheduler.simple.simplescheduler mysql_password=linux rabbit_password=openstack admin_password=openstack service_password=openstack service_token=tokentoken dest=/opt/stack screen_logdir=$dest/logs/screen syslog=true bs_fl_controllers_port=localhostip:port bs_fl_controller_timeout=20 __________________________________________________________ 

now able create instance using command quantum net-create net1 & quantum subnet-create when try boot instance via cli using above created network, instance goes error state. here syslog patch: _________________________________
