Openstack Icehouse - VNC console not connecting to server

Make sure that the setting in the controller and compute node are correct and also double check the IP's.  And replace the host-name with the IP.

controller - 192.168.216.130

running:
nova-consoleauth
nova-novncproxy

nova.conf:
novncproxy_host=0.0.0.0
novncproxy_port=6080
novncproxy_base_url=http://192.168.216.130:6080/vnc_auto.html

compute - 192.168.216.140

Openstack Icehouse Part 6 : Testing the Setup + Horizon

Creating the Key

$ ssh-keygen

Add the public key to your OpenStack environment:
$ nova keypair-add --pub-key ~/.ssh/id_rsa.pub demo-key

Verify addition of the public key:
$ nova keypair-list
+----------+-------------------------------------------------+
| Name | Fingerprint |
+----------+-------------------------------------------------+
| demo-key | 6c:74:ec:3a:08:05:4e:9e:21:22:a6:dd:b2:62:b8:28 |

+--------------------------------------+---------------------+--------+--------+
Your first instance uses the cirros-0.3.2-x86_64 image.

List available networks:

+--------------------------------------+----------+-------------------------------------------------------+
Your first instance uses the demo-net tenant network. However, you must reference this network using the ID instead of the name.

List available security groups:

$ nova secgroup-list

Creating a New flavor

nova boot --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=8cc217b0-96a6-4e98-a901-a694ebff173f --security-group default --key-name demo-key demo-instance1

Creating the instance from back end

nova boot --poll --flavor m1.tiny --image cirros-0.3.2-x86_64 --nic net-id=69c6ca95-2f5d-4173-8973-164c5129cb27 --security-group default --key-name Chumma demo-instance

 

Install Horizone on Controller Node

yum install memcached python-memcached mod_wsgi openstack-dashboard

Edit /etc/openstack-dashboard/local_settings:

ALLOWED_HOSTS = ['localhost', 'my-desktop']
service httpd start
service memcached start
chkconfig httpd on
chkconfig memcached on

 

Openstack Icehouse Part 5 : Configuring EXTERNAL NETWORK

To create the external network on controller

source /root/admin-openrc.sh

neutron net-create ext-net --shared --router:external=True

To create a subnet on the external network

neutron subnet-create ext-net --name ext-subnet --allocation-pool start=192.168.255.160,end=192.168.255.180 --disable-dhcp --gateway 192.168.255.2 ext_net 192.168.255.0/24
#To create the tenant network

source /root/demo-openrc.sh

#Create the network:

neutron net-create demo-net

#To create a subnet on the tenant network

neutron subnet-create demo-net --name demo-subnet --gateway 10.0.0.1 10.0.0.0/24

#Create the router:

neutron router-create demo-router

#Attach the router to the demo tenant subnet:

neutron router-interface-add demo-router demo-subnet

#Added interface b1a894fd-aee8-475c-9262-4342afdc1b58 to router demo-router.

neutron router-gateway-set demo-router ext-net

#Set gateway for router demo-router

 

Now check whether the gateway of the external-network here it will be 192.168.255.160 which is first Ip of the range. Try pinging to the IP and if its not working Stop there and remove all the routers and gateway and redo it using the ID.  If the gate way Don't get pinged the instance won't be able to access outside the network.

 

Set the neutron router-interface-add  and neutron router-gateway-set  BY ID

neutron router-list
