[Openstack] Quantum Debug

Good day everyone,

I am doing a Folsom install following this guide:
https://github.com/EmilienM/openstack-folsom-guide

I only have set up the internal network and I can swpan instances but it
doesn't seem like I can connect to them at all, and they cannot find the
metadata host.

I have 3 interfaces in the cloudcontroller: the management one eth0, the vm
traffic one eth1 and a the external one eth2 which im not using for
anything at the moment.

The thing is after setting up Quantum in the cloudcontroller I cannot even
ping the compute node in eth1 any more (cc is 10.1.1.10 and cn is
10.1.1.20).

My set up was to create a Quantum network, then a subnet (10.1.1.0/24) and
then a router a attach the port to that subnet. I am using Quantum tunnels
too no VLAN.

Does anyone has any clue? Any recommendantions to debug Quantum? Of course
I cannot ping the instances neither.

My interfaces are:

And when I try to ping always get:
