OpenStack environment notes
Environment creation
Before start actual deployment process please verify that you vSphere infrastructure (vCenter and NSXv) is configured and functions properly, Fuel NSXv plugin cannot deploy vSphere infrastructure, it must be up and running before OpenStack deployment.
To use NSXv plugin create new OpenStack environment via the Fuel web UI follow these steps:
On Compute configuration step tick 'vCenter' checkbox
After plugin gets installed it will be possible to use Neutron with NSXv plugin at 'Networking Setup' step:
Once you get environment created add one or more controller node.
Pay attention on which interface you assign Public network, OpenStack controllers must have connectivity with NSX Manager host through Public network since it is used as default route for packets.
Is is worth to mention that it is not possible to use compute nodes in this type of cluster, because NSX switch is available only for ESXi, so it is not possible to pass traffic inside compute node that runs Linux and KVM. Also it does not matter on which network interface you assign Private traffic, because it does not flow through controllers.
Floating IP range settings on Networks are not used by the plugin, because it user interface restricts specifying IP range is not within Public network range. Plugin has its own Floating IP range setting.
Pay attention that Neutron L2/L3 configuration on Settings tab does not have effect in OpenStack cluster that uses NSXv. These settings contain settings for GRE tunneling which does not have an effect with NSXv.
During deployment process plugin creates simple network topology for admin tenant. It creates provider network which connects tenants with transport (physical) network, one internal network and router that is connected to both networks.
