(1) Setup a couple of env. variables:

  $ PRIV_NET=$(neutron net-list | grep private | awk '{print $2;}')
  $ EXT_NET=$(neutron net-list | grep public | awk '{print $2;}')
  $ ROUTER_ID=$(neutron router-list | grep router1 | awk '{print $2;}')


(2) Set the gateway for router:

  $ neutron router-gateway-set $ROUTER_ID $EXT_NET
  Set gateway for router b04ccfed-3613-4e87-a412-c3c13185a96d


(3) Add security group rules to enable `ping` and `ssh`:

  $ 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 default

(4) Check the value of 'force_config_drive' in nova.conf:

  $ grep force_config_drive /etc/nova/nova.conf 
  force_config_drive = False

(5) Boot an instance:

  $ nova boot --image cirros-0.3.3-x86_64-disk --nic net-id=$PRIV_NET \
     --flavor m1.small --key_name oskey1 cirrvm1 \
     --security_groups default

(6) Enumerate the instance:

  $ nova list
  +--------------------------------------+---------+--------+------------+-------------+------------------+
  | ID                                   | Name    | Status | Task State | Power State | Networks         |
  +--------------------------------------+---------+--------+------------+-------------+------------------+
  | 95e32cea-5f04-49e7-a875-c70d4d92cde4 | cirrvm1 | ACTIVE | -          | Running     | private=10.1.0.3 |
  +--------------------------------------+---------+--------+------------+-------------+------------------+


(7) Enumerate the block devices associated with the instance

  $ sudo virsh list
   Id    Name                           State
  ----------------------------------------------------
   2     instance-00000001              running

  $ sudo virsh domblklist instance-00000001
  Target     Source
  ------------------------------------------------
  vda        /home/kashyapc/src/cloud/data/nova/instances/95e32cea-5f04-49e7-a875-c70d4d92cde4/disk
