Hi Amir,

A couple of recommendations:

- Your vxlan_group setting has an extra dot at the end that may be causing issues:
[ml2_type_vxlan]
vxlan_group = 239.0.0.0.
- Your [OVS] block has some incorrect options. Use underscores rather than spaces:
[ovs]
bridge_mappings = public:br-ex
local_ip = 192.168.100.100
vxlan_udp_port = 8472
tunnel type = vxlan
tunnel id ranges = 1001:2000
tenant network type = vxlan
enable tunneling = true
- Same goes for [agent] as well:
[agent]
tunnel_types = vxlan
root_helper_daemon = sudo /usr/local/bin/neutron-rootwrap-daemon /etc/neutron/rootwrap.conf
root_helper = sudo /usr/local/bin/neutron-rootwrap /etc/neutron/rootwrap.conf
#tunnel_types = vxlan
vxlan_udp_port = 8472
l2 population = false
Start by correcting those issues and restart the OVS agents across your hosts. The agent log may be of help here as well.

When I am trying to ping from Linux physical host to Openstack VM (not floating IP) using same subnet L2 address (example ping from 192.168.10.10 to 192.168.10.11) UDP packets on port 8472 are coming to Openstack br-ex interface with ARP request.
