We are installing Kilo over Ubuntu-14.04 over Virtual Box. Installed controller on one node and compute on another node. But "nova-compute is down in nova service-list".

root@controller:~# nova service-list

root@controller:~#

In the Compute, I observed the error message as shown below :- nova-compute.log

raise exception.ComputeHostNotFound(host=host)
ComputeHostNotFound: Compute host compute1 could not be found.

Can anyone guide me how to debug the issue ?

Can you check if openstack-nova-compute is running, check if connects to rabbitmq and also, checkl if neutron agent-list show all OK. Regards

I solved the problem. Below is the analysis. controller version and compute version are not compatible. So, its failing. So, updated the openstack respository on compute to pick the latest.

Followed the openstack instal document and executed the below commands for ubuntu-14.04

apt-get install ubuntu-cloud-keyring

echo "deb http://ubuntu-cloud.archive.canonical.com/ubuntu%22 (http://ubuntu-cloud.archive.canonical...) \ "trusty-updates/kilo main" > /etc/apt/sources.list.d/cloudarchive-kilo.list

apt-get update && apt-get dist-upgrade

service nova-compute restart

This solved the issue. Hope it helps others who are having the same issue.
