Hi, Yipei, The issue is that the OS_REGION_NAME should be “Pod2” for the Node2 for Nova,Cinder, Neutron endpoint registration in KeyStone, but when creating endpoint in Keystone, devstack will use command like “openstack endpoint create” to access KeyStone, the OS_REGION_NAME should be the region name where the KeyStone located, in two-nodes installation, it should be “RegionOne” for the command itself.
So it can be fixed by adding one more configurable global variable to separate KeyStone region name and other services(Nova,Cinder,Neutron) region name.

I insert a command "export OS_REGION_NAME=Pod2" in line 1262 in stack.sh and it works. However, I am not sure whether it is correct. I am trying to verify it. Recently, I try to re-install devstack on node1, but I encounter some errors. The link is http://paste.openstack.org/show/488005/. Do you have any suggestion about it? To Joe and Zhiyuan, could you please give me some advice about how to solve it?
