Not all systems that support Open vSwitch support its GRE tunneling 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_tunneling is False, the server will not allow creation of GRE 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. Change-Id: I149db182dd132cc05802dcb20c6b552e293664a5
