Public bug reported:

my nova.conf like this:
network_api_class=nova.network.neutronv2.api.API
use_neutron=True

when I create a vm because nova-compute not found the glance image then a exceptin occure:

I use the neutron for netowrk but the error log show that nova-conductor use nova-network rpc api
for example the code:File "/usr/lib/python2.7/site-packages/nova/network/api.py", line 299, in deallocate_for_instance 
in fact it should use /usr/lib/python2.7/site-packages/nova/network/neutronv2.api.py

why? I guess maybe I create a error instance then the bug occure
if I create a active instance the bug will not be occure
