Guys,

I trying to enable the GRE tunnels in my Havana environment but, I'm seeing
the following error messages at my Controller Node, after restarting
`neutron-plugin-openvswitch-agent`:

I'm following the same topology described here:

https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst

But, of course, make the changes to reflect Havana needs, as package names
and etc...

My Instances doesn't get an IP from the DHCP. I'm running the command
`tcpdump -ni eth1` at my Network Node (interface used by OVS for the GRE
tunnel) and I'm seeing the DHCP requests coming into the Network Node but,
it does not reach DHCP server within the tenant namespace...

I mean, from the inside of tenant's "qdhcp-*" Namespace, there is no DHCP
requests hitting it.

Apparently, the GRE tunnel is UP, since at the Network Node, I can see the
DHCP requests coming from the Intances but, they never hit the tenant DHCP
server within its own Namespace...

I already tried to start again from scratch, this error messages appear
before creating new Networks and Subnets with Neutron. Later, the Instances
doesn't get an IP...

I'm using Ubuntu 12.04.3 - Linux 3.8 - OVS 1.10.2 from Havana Cloud Archive.

Any tips?!

Thanks!
Thiago
