Description lpeer 2014-06-12 10:23:42 UTC 
Description of problem:

The 'enable_tunnelling' was deprecated in Icehouse and is not relevant for OSP-5 as the kernel version already support GRE/Vxlan, therefore should be removed.

Taken from ovs_neutron_plugin.ini comments -
# (BoolOpt) Set to True in the server and the agents to enable support
# for GRE or VXLAN networks. Requires kernel support for OVS patch ports and
# GRE or VXLAN tunneling.
#
# WARNING: This option will be deprecated in the Icehouse release, at which
#          point setting tunnel_type below will be required to enable
#          tunneling.

Jay, does this need to be removed from OFI side as well?
Comment 3 Scott Seago 2014-06-12 13:59:28 UTC 
For non-HA controller this is an easy fix.
Comment 4 Jason Guiditta 2014-06-13 15:58:32 UTC 
Mike, it would need to be removed from ofi, yes, otherwise the staypuft change just hides the param.  Livnat, I would like to verify though that the kernel you say supports this would be available in all expected openstack icehouse target platforms (RHEL 7 I assume yes, but what about RHEL 6.6? 6.5?).  If no, does it actually hurt anything to leave this?  I would rather have an extra param if it makes things more likey to work on certain platforms, than to have one less with breakage in certain situations.  Actual removal is pretty trivial on our side, just want to verify we have thought through the scenarios

Comment 6 lpeer 2014-06-16 07:08:09 UTC 
The code in Icehouse is looking at the 'tunnel_type' config value if there is value there (gre or vxlan) the enable_tunneling is override with true.
Which means this value is ignored regardless of the kernel support. 

Regardless RHEL 6.5 and RHEL 7.0 have support in vxlan and gre so it can be safely removed.
