The current method of checking openvswitch and kernel versions for specific feature support is brittle, distro-specific and unsupportable. This patch removes the runtime version checks and implements a test script which allows testing specific neutron features or can test that all features required by a specific configuration are available. For example, to test VXLAN support in openvswitch, either: neutron-sanity-check --ovs_vxlan or pass in the deployed configuration files with AGENT/tunnel_types containing 'vxlan', like: neutron-sanity-check --config-file /etc/neutron/plugins/ml2.conf.ini Deployment tools can then test that the required features exist without relying on version numbers and without incurring a penalty every time the agent is started. Implements: blueprint remove-openvswitch-version-check DocImpact Change-Id: I5e822d97b9bece9242ba5ac8901aa0ca4f090cfe
