400 error when launching an instance

[Lan Qi song]

When I was tring to launch an instance with powervm driver. The following error occurred:

2017-05-16 16:53:33.561 14395 TRACE nova.compute.manager [instance: 2946705d-11a4-4d78-818e-682585dbe12d] raise self._get_httperror(resp)

Seems "TargetDeviceUniqueDeviceID" is missed when create_disk_from_image, and the "UniqueDeviceID" is not returned through VolumeGroup api, the following is "VirtualDisk" parts output from VolumeGroup Api:

Can you provide more details, how u tried to launch instance, did you used the Openstack horizon,
or the REST API,
If you used the REST API please share the Request body

I used nova boot command line as follow:

nova boot --image cirros --nic net-id=e2f84e34-fbb1-445b-a973-24e4e2507106 --flavor 1 instance01

The vios version:
$ ioslevel
2.2.2.0

HMC version: V8R8.6.0

[Drew Thorstensen (thorst)]

Lan Qi song - are you using the HMC or NovaLink for the PowerVM drivers?

The PowerVM drivers are only supported on a PowerVM NovaLink based system.

[Lan Qi song (lqslan)]

Hmm, I am using HMC. From the guide, the NovaLink based system is only supported by power8, what if the previous version of power, how can I manage them.

Before the NovaLink be born, the HMC should be ok, right ?

[Drew Thorstensen (thorst)]

We're discussing in IRC. But the drivers don't have support for anything other than PowerVM NovaLink based management.
