Currently, even when [libvirt] volume_use_multipath is set to True, volume attachment silently falls back to single path if multipathd is not running in the host. This sometimes prevents operators from noticing the misconfiguration, until they face any issue caused by missing redundancy. Introduce the new [libvirt] volume_enforce_multipath option, which makes the attachment process fail if multipathd is not running. A similar parameter (enforce_multipath_for_image_xfer) was already implemented in cinder and this change follows how the parameter is implemented there. Also add the check in init phase to detect lack of mulitipath daemon during initializing driver. Min version of os-brick has to be bumped due to the interface change made by 8d919696a9f1b1361f00aac7032647b5e1656082 . Implements: blueprint enforce-multipath Change-Id: I828de70ca7b343a4562ace4049d2b3857dbf900a

OpenStack Nova provides a cloud computing fabric controller, supporting a wide
variety of compute technologies, including: libvirt (KVM, Xen, LXC and more),
VMware and OpenStack Ironic.
Use the following resources to learn more.
API
---
To learn how to use Nova's API, consult the documentation available online at:
- `Compute API Guide <https://docs.openstack.org/api-guide/compute/>`__
- `Compute API Reference <https://docs.openstack.org/api-ref/compute/>`__
For more information on OpenStack APIs, SDKs and CLIs in general, refer to:
- `OpenStack for App Developers <https://www.openstack.org/appdev/>`__
- `Development resources for OpenStack clouds
<https://developer.openstack.org/>`__
Operators
---------
To learn how to deploy and configure OpenStack Nova, consult the documentation
available online at:
- `OpenStack Nova <https://docs.openstack.org/nova/>`__
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:
- `Bug Tracker <https://bugs.launchpad.net/nova>`__
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.
To understand better the processes that the team is using, please refer to the
`Process document <https://docs.openstack.org/nova/latest/contributor/process.html>`__.
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
