Open Stack

Hi,

I am trying to use vxlans in Havana. I have two nodes, one acting as
controller+network node and other as compute node.

VM's launched have not got the dhcp ip.

I have compiled openvswitch from openvswitch-2.0.0 tar ball and installed
both userspace and kmod rpms.

modinfo openvswitch
filename:
/lib/modules/3.9.5-301.fc19.x86_64/kernel/extra/openvswitch/openvswitch.ko
version:        2.0.0
license:        GPL
description:    Open vSwitch switching datapath
srcversion:     4728289FE3C06CF45730614
depends:        libcrc32c,gre
vermagic:       3.9.5-301.fc19.x86_64 SMP mod_unload

My kernel version is 3.9.5-301.fc19.x86_64.

I am using ml2 plugin and here is the configuration w.r.t vxlans

ml2_conf.ini
type_drivers = vxlan
vni_ranges = 100:1000
vxlan_group = 239.10.10.1
enable_tunneling = True
local_ip = 21.21.21.11--------------> This is the ip of the interface which
is used as data network
tunnel_types = vxlan

ovs_neutron_plugin.ini
tunnel_id_ranges = 200:1000

Similar configuration exists on compute node as well.
Below is ovs dump on controller.

I see some error/warning logs in openvswitch logs

I also don't see patch-tun, patch-int or vxlan-21.21.21.10 in ifconfig.

Could you please help me resolve the issue

Regards,
Kanthi
