Hi Joe and Zhiyuan,

I encounter an error when executing the following command:

stack at nyp-VirtualBox:~/devstack$ curl -X POST http://192.168.56.101:19999/v1.0/pods -H "Content-Type: application/json" -H "X-Auth-Token: 0ead350329ef4b07ab3b823a9d37b724" -d '{"pod": {"pod_name":  "RegionOne"}}'
curl: (7) Failed to connect to 192.168.56.101 port 19999: Connection refused

Before executing the command, I source the file "userrc_early", whose content is as follows:
export OS_IDENTITY_API_VERSION=3
export OS_AUTH_URL=http://192.168.56.101:35357
export OS_USERNAME=admin
export OS_USER_DOMAIN_ID=default
export OS_PASSWORD=nypnyp0316
export OS_PROJECT_NAME=admin
export OS_PROJECT_DOMAIN_ID=default
export OS_REGION_NAME=RegionOne

Furthermore, the results of "openstack endpoint list" are as follows:

+----------------------------------+-----------+--------------+----------------+---------+-----------+------------------------------------------------+

Since current solution to fixing the bug of multi-region setting in devstack needs to be further verified, I am not sure whether the error is caused by the solution or not.

Best regards,
