Hi Sushma,

Thanks for the reply.

Well, edit /etc/nova/policy.json do works for command "nova migrate".

But when I run command "nova live-migration", I still get errors, in  /var/log/nova/conductor.log:

Hi Li,

As fas as I know to migrate an instance you'll need admin priviliges.
But if you want to allow this operation for normal user then might try editing /etc/nova/policy.json file and give privileges.

File: /etc/nova/policy.json
change "compute_extension:admin_actions:migrate": "rule:admin_api" to
"compute_extension:admin_actions:migrate": "rule:admin_or_owner"


Regards,
Sushma

Subject: [Openstack] How can I enable operation for non-admin user

Hi list,

I'm working under CentOS + icehouse.

While, I have an non-admin user "demo", and I can work under this this user with basic operations.
Everything works well.

But, I also hope this user can do some admin operations, such as migrate and so on, because currently when I run command:
nova migrate ${my_instance}
I get output:
ERROR: Policy doesn't allow compute_extension:admin_actions:migrate to be performed. (HTTP 403) (Request-ID: req-698ad5b5-f1fe-48fc-b81f-a765020bf89f)

Anyone can help me ?

Thanks.
-chen
