Hi everyone,

I'm testing the upgrade process from Ocata to Pike in lab, and after 
upgrading the environment, when I try to launch a new instance, nova 
fails to launch the instance.

nova-compute.log reports:
/BuildAbortException: Build of instance 
a7054a4a-7d4a-49f0-ba32-1507d271822b aborted: Failed to allocate the 
network(s), not rescheduling.

/INFO neutron.agent.common.ovs_lib 
[req-a8a13dca-330f-4e18-ac2c-7a7aac98aa3d - - - - -] Port 
932c5eb6-210f-42c4-a2c4-df47fe8a1834 not present in bridge br-int/

Anyone can give a clue? :)

Thanks in advance,
