Dear Dan, I have changed my /etc/nova/nova.conf file to reflect proper fixed_ip range,
then it start to launch. I have one more question, does the compute nodes required to have all the nova softwares to run. because on my slave nodes initially it was only nova-compute, later installed nova-scheduler, api, network n all. Started multiple instances from master node, able to create vm on slave nodes, but the status is shutdown. No idea. if I am able to access these from slave nodes, it requires EC2_ACCESS_KEY. By default it is not set, do I need to set it manually. Could any one please clarify my doubts. --Thanks and regards, Praveen GK.
