Bug Description
The openvswitch agent, with no quantum ports existing, logs at a rate of about 3 MB per hour using devstack, which is about 10 times the rate of nova compute, the next most verbose service. The rate could be much higher on a busy system. Both to reduce disk usage and to make it possible to find messages related to real issues, openvswitch deployments will need to disable logging at the debug level. There currently are a number of abnormal conditions logged at the debug level that should be logged as warnings or errors instead. Also, the bridge mappings at startup should be logged at info rather than debug level.

Add enable_tunneling openvswitch configuration variable
Not all systems that support Open vSwitch support its GRE tunneling tunneling is False, the server will not allow creation of GRE
feature that is not in the Linux kernel source tree. Therefore, a new
configuration variable, enable_tunneling, applies to both the server
and agent. Its default value is False, so it must be set to True to
enable tunneling for tenant and/or provider networks. If
enable_
networks, and the agent will not initialize the tunnel bridge and will
log an error if there is an attempt to provision a GRE network. If it
is True, the agent now logs an error and exits if it fails to
initialize the patch ports used for the tunnel bridge. Fixes bug
1045610.
When there is an attempt to provision a flat or VLAN network and the
agent has no bridge mapping configured for a the specified physical
network, the agent will now log an error rather than crash.
An undefined variable in a logging statement has been corrected.
Logging levels for openvswitch have been checked and updated where
necessary, and logging statements now avoid the % string substitution
syntax. Fixes bug 1045592.
The corresponding devstack update has already been merged.
