I have OpenStack Havana installed I am able to launch Ubuntu/CirrOS instance but I am not able to ping or ssh to instance and vice-versa.

I had set this in local.conf

HOST_IP=192.168.171.131
FLAT_INTERFACE=eth0
FIXED_RANGE=10.11.12.0/20
FIXED_NETWORK_SIZE=4096
FLOATING_RANGE=192.168.172.128/25
MULTI_HOST=1

What public and private network configuration are recommended?

Maybe a better start for you would be RDO Havana on CentOS 6.5

You just install repos required and run
$ packstack --allinone
Take a look at RDO Site
It's just for start. Ubuntu doesn' have puppet technology like CentOS 6.5 or Fedora 20.
Having built for you via packstack working Havana AIO Server. You would be able to
to learn much faster. Devstack on Ubuntu is also option

Source tenants credentials and run

   $ neutron security-group-rule-create --protocol icmp \
      --direction ingress --remote-ip-prefix 0.0.0.0/0 default

    $ neutron security-group-rule-create --protocol tcp \
      --port-range-min 22 --port-range-max 22 \
      --direction ingress --remote-ip-prefix 0.0.0.0/0 defau

If it has been done. I would perform troubleshooting following 1 and 2

I have those rules added to default group. but still does not work. I have actually Ubuntu 12.04 inside VMWare WorkStation 10 and OpenStack Havana installed in it.

I believe that either L2 or L3 routing is broken. So , I need to work with qdhcp-* and qrouter-* namespaces
and compare obtained results with ovs-vsctl show output (br-int tap-interfaces subtree & br-ex tap-interfaces subtree).

I am new to OpenStack and networking. Don't know what are you saying. :(
