Ameed Ashour 61f6751a18 Detach volumes when VM creation fails
If the boot-volume creation fails, the data volume is left in state
"in-use", attached to the server which is now in "error" state.
The user can't detach the volume because of the server's error state.

They can delete the server, which then leaves the volume apparently
attached to a server that no longer exists, which is being fixed
separately: https://review.openstack.org/#/c/340614/

The only way out of this is to ask an administrator to reset the state of
the data volume (this option is not available to regular users by
default policy).

This change fixes the problem in the compute service such that
when the creation fails, compute manager detaches the created volumes
before putting the VM into error state. Then you can delete the instance
without care about attached volumes.

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.

Further developer focused documentation is available at:

Other Information

During each Summit and Project Team Gathering, we agree on what the whole community wants to focus on for the upcoming release. The plans for nova can be found at:
