Hi Sergii/Miroslav,

I have shared the “Diagnostic Snapshot” at https://www.dropbox.com/s/79op6pi1vxe9w9l/fuel-snapshot-2014-06-19_04-40-10.tgz

Topology:
Our topology is like below –
[cid:image001.png@01CF8BB9.B56290A0]
Query: nova hypervisor-list is empty in compute node

Steps we tried for ‘neutron agent-list’:
Neutron agent-list was also not listing host-node5 (highlighted below) by default. After we changed the IP address from 192.26.0.3(management network) to 10.24.41.3(public network) in Compute node -> neutron.conf file and restarting neutron service, node-5 agent got listed successfully.

Line modified from 192.26.0.3 to 10.24.41.3 in Compute Node-Neutron.conf file:
connection = mysql://neutron:XXqqP4LM@10.24.41.3:3306/neutron?read_timeout=60

Compute Node – neutron agent-list:
root@node-6:/etc/neutron# neutron agent-list

Steps we tried to display compute node in ‘nova hypervisor-list’:
We have replaced all the references of 192.168.0.3 to 10.24.41.3 in Compute node -> /etc/nova/nova.conf file.
Also modified Compute node -> /etc/nova/nova-compute.conf with the below lines -

            [DEFAULT]
compute_driver=libvirt.LibvirtDriver
#sql_connection=mysql://nova:gfW4v98X@10.24.41.3/nova?charset=utf8

Hi Gandhirajan,
From your email it's not clear a topology your have. I am kindly asking to create "Diagnostic snapshot" so we'll be able to analyze it. The link below will help you with the process

Thank you.
