-# Network overlay supported by openvim compute, bsae on openvswicth or linux bridges to manage management networks for NFVs.
-# - ovs : Create a vlxan mesh between computes to handle the network overlay, no prepopulated bridges or networks is need it.
-# - bridge: Use pre-populate linux bridges by openvim configuration scripts.

+# Overlay network implementation. Options are:
+# - ovs : (by default) Use a vlxan mesh between computes to handle the network overlay.
+# - bridge: Use pre-populated linux bridges with L2 conectivity at compte nodes.
