As I can't connect to my controller node ( I lost my connection to it) I'm
uploading here the files I found on my compute node.

[ovs]
# (StrOpt) Type of network to allocate for tenant networks. The
# default value 'local' is useful only for single-box testing and
# provides no connectivity between hosts. You MUST either change this
# to 'vlan' and configure network_vlan_ranges below or change this to
# 'gre' or 'vxlan' and configure tunnel_id_ranges below in order for
# tenant networks to provide connectivity between hosts. Set to 'none'
# to disable creation of tenant networks.
#
# tenant_network_type = local
# Example: tenant_network_type = gre
# Example: tenant_network_type = vxlan

# (ListOpt) Comma-separated list of
# <physical_network>[:<vlan_min>:<vlan_max>] tuples enumerating ranges
# of VLAN IDs on named physical networks that are available for
# allocation. All physical networks listed are available for flat and
# VLAN provider network creation. Specified ranges of VLAN IDs are
# available for tenant network allocation if tenant_network_type is
# 'vlan'. If empty, only gre, vxlan and local networks may be created.
#
# network_vlan_ranges =
# Example: network_vlan_ranges = physnet1:1000:2999

# (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.

# enable_tunneling = False

# (StrOpt) The type of tunnel network, if any, supported by the plugin. If

# bridge names to be used for flat and VLAN networks. The length of
# bridge names should be no more than 11. Each bridge must

# port. All physical networks listed in network_vlan_ranges on the
# server should have mappings to appropriate bridges on each agent.
#
# bridge_mappings =

# (ListOpt) The types of tenant network tunnels supported by the agent.
# Setting this will enable tunneling support in the agent. This can be set to
# either 'gre' or 'vxlan'. If this is unset, it will default to [] and
# disable tunneling support in the agent. When running the agent with the OVS
# plugin, this value must be the same as "tunnel_type" in the "[ovs]" section.

# Example: veth_mtu = 1504

# (BoolOpt) Flag to enable l2-population extension. This option should only be
# used in conjunction with ml2 plugin and l2population mechanism driver. It'll
# enable plugin to populate remote ports macs and IPs (using fdb_add/remove
# RPC calbbacks instead of tunnel_sync/update) on OVS agents in order to
