In addition to the information below, ensure that your new hypervisor node's network interfaces match those of an existing hypervisor (i.e. Bridge and VXlan, etc...)
$ cmsh -c "device; use n08; interfaces; list"
Type Network device name IP Network
------------ -------------------- ---------------- ----------------
alias br0:vxlan 10.161.0.8 vxlanhostnet
bridge br0 [prov] 192.168.17.8 internalnet
physical BOOTIF (br0) 0.0.0.0
Answer from Curtis in support:
"The set of nodes can be changed on a cluster later on, by managing the node list of the OpenStackHyperVisors configuration overlay."
This is on page 39. All that should be required is just adding the node to that "nodes" list. From there, the CO will take over and the role attached to the overlay should install and start the services:
https://support.brightcomputing.com/manuals/8.2/openstack-deployment-manual.pdf#subsection.3.2.638
This should be the steps:
# cmsh
% configurationoverlay
% use openstackhypervisors
% show (to see the current list)
% append nodes <which-node-you-want>
% commit
