Greetings, Praveen! On your compute nodes, the only required service is nova-compute. There has been a semi-recent update to nova-network that adds HA to the service, and this requires nova-network to be installed on all the compute nodes as well. As far as api and scheduler go, they are not required on every node.
For more information on nova-network's HA work, check out Vish's blog: http://www.unchainyourbrain.com/openstack/13-networking-in-nova Cheers, Wayne From: praveen_kumar girir <gkpra...@gmail.com> Date: Thu, 18 Aug 2011 09:28:32 +0530 To: Dan Wendlandt <d...@nicira.com> Cc: openstack <openstack@lists.launchpad.net> Subject: Re: [Openstack] Unable to run instances , instance status is networking, 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.
