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.

  • You will get only generic error messages from front end / command outputs. You need to check logs for detailed error messages and exceptions. tail neutron log and nova compute log in two terminals. Then try to launch instance. You will get correct error message. Search with that error message might lead you to the solution. Issue command neutron agent-list and make sure all components are alive. – Harikrishnan Jul 29 '15 at 06:55

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.
