nova scrub doesn't remove a vm

[Jaroslav Henner]

Checking the code, nova scrub should disassociate the network associated with the given tenant, but it fails to do so. There is no error in log.

I have found that not-disassociating the network is caused by leftover VMs in that network. I think nova scrub should remove the VMs first, then it should disassociate the network.

I don't see that nova scrub even does anything to my instance

Not quite sure what: Delete data associated with the project means exactly either. What is scrub supposed to do?

Accordig to http://docs.openstack.org/cli-reference/nova.html, nova scrub isn't supposed to remove a vm, only "Delete networks and security groups associated with a project". This bug doesn't seem valid.
