Hi guys,

we are facing issue when we launch instance after configuring network neutron. our set has controller,compute, neutron nodes. We have successfully completed controller+compute+neutron integration with single flat network.

root@neutron:~# neutron net-list

first check that your services do work right

nova-manage service list
