Instance creation in devstack icehouse

Question

I want to create few instance having ubuntu installed on it using openstack.

I tried following steps

Approach 1

1. installed icehouse devstack

   git clone -b stable/icehouse https://github.com/openstack-dev/devstack.git
   cd devstack
   ./stack.sh
   

2. after successful installation i uploaded a ubuntu image

   glance image-create --name Ubuntu --disk-format  iso --container-format bare <~/sumit/images/ubuntu-14.04.2-desktop-amd64.iso
   

3. login to dashboard and launch the instance (m1.small, RAM GB, total disk 20GB) using this image.

4. open the instance console from horizon dashboard and try to install ubuntu

Βut it shows required space(6.5GB) in not available.

Τhen I tried to install neutron and heat also

Approach 2

1. installed icehouse devstack

   git clone -b stable/icehouse https://github.com/openstack-dev/devstack.git
   cd devstack
   vi localrc
   

   my localrc looks like

   DEST=/opt/stack
   LOGFILE=$DEST/logs/stack.sh.log
   VERBOSE=True
   LOG_COLOR=False
   SCREEN_LOGDIR=$DEST/logs/screen
   
   ADMIN_PASSWORD=password 
   MYSQL_PASSWORD=openstack
   RABBIT_PASSWORD=openstack
   SERVICE_PASSWORD=openstack
   SERVICE_TOKEN=tokentoken
   
   GLANCE_BRANCH=stable/icehouse
   HORIZON_BRANCH=stable/icehouse
   KEYSTONE_BRANCH=stable/icehouse
   NOVA_BRANCH=stable/icehouse
   NEUTRON_BRANCH=stable/icehouse
   HEAT_BRANCH=stable/icehouse
   CEILOMETER_BRANCH=stable/icehouse
   
   DISABLED_SERVICES=n-net ENABLED_SERVICES+=,q-svc,q-agt,q-dhcp,q-l3,q-meta,q-metering,neutron
   
   ENABLED_SERVICES+=,q-lbaas
   ENABLED_SERVICES+=,heat,h-api,h-api-cfn,h-api-cw,h-eng
   HEAT_STANDALONE=True
   
   ENABLED_SERVICES+=,ceilometer-acompute,ceilometer-acentral,ceilometer-collector,ceilometer-api
   ENABLED_SERVICES+=,ceilometer-alarm-notify,ceilometer-alarm-eval
   

   After this

   ./stack.sh
   

2. after successful installation Ι uploaded a ubuntu image

   glance image-create --name Ubuntu --disk-format  iso --container-format bare <~/sumit/images/ubuntu-14.04.2-desktop-amd64.iso
   

3. login to dashboard and launch the instance (m1.small, RAM GB, total disk 20GB) using this image.

   But now it displays

   Error: Unable to connect to Neutron
   

   Every time Ι list the instance it displays same error.

Can anyone help me out to overcome all these problems so that Ι can launch some instances and install ubuntu on that.

Answer 1

Unable to connect can be because neutron service is not running. Through Dashboard you cannot create instance without network. Use screen command in devstack to check if neutron is running properly.
