how to add additional compute nodes?

Following the Ubuntu install guide, my first compute node is up and running, and shows up on the dashboard under the 'hypervisors' tab. I've just carried out the relevant instructions in the 'Configure Compute services' and 'Add a networking service' for adding a second compute node, but it's not being reported in dashboard, or with 'nova hypervisor-list'.

What is the mechanism whereby the controller node picks up additional compute nodes? Since I would assume it's a push model, where the compute nodes tell the controller they are available...

So what am I missing here: services I should restart, any steps not mentioned in the install guide?

Any help appreciated!

edit: gone a little further with this. After copying the nova.conf file from the other compute node and then modifying the IP entries, when I attempt to start the nova-compute service it crashes immediately on startup. There's absolutely nothing in the logs under /var/log/nova

Did you perform RDO AIO install via packstack ? If "YES" ,then what is the value
CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=?

No, I performed the installation manually, following the Ubuntu Installation guide for Icehouse

Hi Daniel,

you have to setup networking on the compute node and also copy the nova.conf from your controller node. Have you already looked into adding additional compute nodes?

I've done the compute node steps here, as well as network setup for the compute node here.
