[chenwd]

I am the M version of the openstack, I control the node with nova set-password instancesname reset the password, there is an error, my mirror is windows2008, mirror for the manual production, which installed qemu-guest-agent, the service started normal.
The following is my detailed error message:
[Root @ controller01~] #source keystonerc_admin

Is there more to the exception? That doesn't seem to tell much. Which version of libvirt is on the compute node because libvirt >= 1.2.16 is required to set the password in the guest.

Is the guest windows or linux?

Do you see this error in the logs?

We need to see this trace exception message for the original failure to debug this:

https://github.com/openstack/nova/blob/stable/mitaka/nova/compute/manager.py#L3322

[Sylvain Bauza (sylvain-bauza)]

The real problem here is that I don't see a firm stacktrace telling us why we get this exception.

We don't expose the original exception for security purposes but we still log it in the n-cpu log if something goes wrong when setting the password.

Could you please give us the trace given https://github.com/openstack/nova/blob/9f7af83d1ba1795b19a8fec58cd492f842bad98a/nova/compute/manager.py#L3289 ?

You could grab your logs and find for the (maybe translated) pattern "set_admin_password failed"

Please don't paste us translated traces using Google, it's rather better to try giving us the internationalized trace.

The problem has been resolved, thank you.
