[rhos-list] unable to delete an instance

[Vogel Nicolas]

Here are some logs which could help:

Compute.log :

I also have the ERROR "nova [-] need more than 0 values to unpack" or "cinder [-] need more than 0 values to unpack".

And the cinder service is unavailable:
[root at IICT-SV1259 ~(keystone_admin)]$ cinder list
ERROR: n/a (HTTP 400)

Is that a problem from keystone?

We need to go back to figuring out why the instance couldn't be deleted originally.  Do you know how you got it into that state?

If all else fails, the brute force is manually removing the instance from the database and the hypervisor, but you should never have to do that.

Do other nova commands give you that error?  Can you provide the full command and output?
