Hi I have done a 2 node installation of Openstack Havana . One is the controller node and other one is the compute node. I am using nova-compute-qemu for hypervisor. Also I havent installed neutron. I am using nova-network . Both the nodes show that all the services are running fine

Nova-manage service list on controller
nova-cert        controller                           internal         enabled    :-)   2013-12-16 06:46:14
nova-conductor   controller                           internal         enabled    :-)   2013-12-16 06:46:08

But it does not show the hypervisor in Horizon and while launching an install it shows no availability zone. What might be the problem. Is the connection proper?

Do i require bridges for the connection between the compute node and the controller node? Current I just have two ethernet adapters on each node one internal and one external and no bridges.

Can you post the `sql_connection` setting from `/etc/nova/nova.conf` on both your controller and compute node? Make sure to anonymize any password before posting.

Compute Node Mysql setting --connection = mysql://nova:nova_password@controller/nova Controller Node Mysql Setting [database] connection = mysql://nova:nova_pass@controller/nova

As given in the manual I have deleted the file /var/lib/nova/nova.sqlite but it comes back again.

Have you restarted all your nova services on the compute node (probably just the nova-compute service)? It really sounds like your compute node has the wrong database setting, but the configuration you posted in your earlier comment seems correct.

yes i have restarted all the services. I am also confused what the problem might be.
