Actually I am working on openstack havana. I have installed and configured the controller node (keystone, glance all packages, cinder all packages, rabbitmq server, nova-novncproxy, novnc, nova-api, nova-ajax-console-proxy, nova-cert, nova-conductor, nova-consoleauth, nova-doc, nova-scheduler, python-novaclient). In compute1 node, nova-compute and nova-network installed and configured. And I created nova network

         nova network-create vmnet --fixed-range-v4=10.0.0.0/24 --bridge=br100 --multi-host=T

When I launch a instance it get the ip address everything working fine in single compute node.

Now I add the compute2 node, only nova-compute installed on the compute2 node. I created zones for both compute nodes. ZoneA for Compute1 and ZoneB for Compute2 node done.

When i launch a instance vm using ZoneB it get some errors in nova-compute log in Compute2 but launched from ZoneA works fine.

Compute2 node: nova-compute.log
