There is the Fuel plugin which provides Neutron for networking on VMware-related MOS environments.
There is only one difference from normal plugin installation way. Before building the plugin you have to patch plugin_rpm.spec.mako file which is a part of the fuel plugin builder.
Just do $ cd /path/to/fuel-plugin-vmware-dvs; sudo patch /path/to/plugin_rpm.spec.mako hack.diff
