During a rebuild we bypass the scheduler because we are always rebuilding the instance on the same host it's already on. However, we allow passing a new image during rebuild and that new image needs to be validated to work with the instance host by running it through the scheduler filters, like the ImagePropertiesFilter. Otherwise the new image could violate constraints placed on the host by the admin. This change checks to see if there is a new image provided and if so, modifies the request spec passed to the scheduler so that the new image is validated all while restricting the scheduler to still pick the same host that the instance is running on. If the image is not valid for the host, the scheduler will raise NoValidHost and the rebuild stops. A functional test is added to show the recreate of the bug and that we probably stop the rebuild now in conductor by calling the scheduler to validate the image.

OpenStack Nova
==============
OpenStack Nova provides a cloud computing fabric controller, supporting a wide
variety of compute technologies, including: libvirt (KVM, Xen, LXC and more),
Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.
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://developer.openstack.org/api-guide/compute/>`__
- `Compute API Reference <https://developer.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.
Further developer focused documentation is available at:
- `Official Nova Documentation <https://docs.openstack.org/nova/>`__
- `Official Client Documentation
<https://docs.openstack.org/python-novaclient/>`__
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
