nova-compute is not coming up in OpenStack Devstack All in One Node Install. While nova services are enable in stackrc

local.conf is also fine. Dashboard is coming up with all the services but compute host is not showing up.It is a physical machine (Ubuntu 12.04 Server), IP address is fixed. etc/hosts has correct entry. Also I have updated and upgraded before running ./stack.sh

nova-compute service is missing shows the below output.

hadoop@hadoop:~/devstack$

Unable to figure out on what am I missing, please help!

local.conf looks like below

hadoop@hadoop:~/devstack$ cat local.conf
# Sample ``local.conf`` for user-configurable variables in ``stack.sh``

# NOTE: Copy this file to the root ``devstack`` directory for it to
# work properly.

# ``local.conf`` is a user-maintained setings file that is sourced from ``stackrc``.
# This gives it the ability to override any variables set in ``stackrc``.
# Also, most of the settings in ``stack.sh`` are written to only be set if no
# value has already been set; this lets ``local.conf`` effectively override the
# default values.

# This is a collection of some of the settings we have found to be useful
# in our DevStack development environments. Additional settings are described
# in http://devstack.org/local.conf.html
# These should be considered as samples and are unsupported DevStack code.

# The ``localrc`` section replaces the old ``localrc`` configuration file.
# Note that if ``localrc`` is present it will be used in favor of this section.
[[local|localrc]]

# Minimal Contents
# ----------------

# While ``stack.sh`` is happy to run without ``localrc``, devlife is better when
# there are a few minimal variables set:

# If the ``SERVICE_TOKEN`` and ``*_PASSWORD`` variables are not set
# here you will be prompted to enter values for them by ``stack.sh``
# and they will be added to ``local.conf``.
