HI, There are two datacenters with two separate installation of openstack that work fine. Every datacenter has 4 compute nodes. Now we want to integrate them, how is it possible? I study (https://wiki.openstack.org/wiki/OpenStack_cascading_solution (https://wiki.openstack.org/wiki/OpenS...)).

It seems, cascading is one way to integrate two datacenters. But actually I need one openstack in two datacenters. Is it possible to change the installation under single keystone?? If yes, then how?

You should investigate the concepts of regions and perhaps cells. Regions are separate OpenStack installations with common authentication. Cells are less independent installations sharing a single Nova API service.

From your description, regions is what you need.
