Open Stack

Hi ,

    I have started working with OpenStack, it’s so interesting with working
in it.



   My Hardware configuration is as



   Processor : Intel(R) Xeon(R) CPU X3330 @ 2.66GHz (VT Enabled)
  Cpu cores : 4
  Ram : 4 GB
  OS : Ubuntu 10.10 (64 bit)



 I configured OpenStack  in my environment by the following link


http://fnords.wordpress.com/2010/12/02/bleeding-edge-openstack-nova-on-maverick/

everything works fine. am able to Launce ,SSH , Ping  &  terminate the
instance.(In the default image provided in the link)



Then I Created a Ubuntu image from scratch. Bundled &  register the image to
my Cloud environment. am able to see the registered images as available .
now my problem is while I launch the image that I created am getting the
status as “pending”



the output of /var/log/nova/nova-compute.log
