Matt Riedemann c62ed630a9 doc: add superconductor up-call caveat for cross_az_attach=False 
When attaching a volume, if CONF.cinder.cross_az_attach=False,
we attempt to lookup the AZ that the instance is in and compare
that to the volume AZ. The instance AZ lookup involves getting
host aggregates which are in the API database, and in superconductor
mode the cell conductor can't access to the API database.

For volume attach, we could remove this check from the compute
service since we already check this in nova-api so the check in
nova-compute is redundant.

However, we still have a problem with checking this during boot
from volume where nova-compute creates the volume and then
attaches it. At that point it's too late and we'll fail.

We should eventually create volumes during boot from volume in
conductor, like we've talked about doing with neutron ports
during server create, but that's not something we have today
so we need to point out this limitation.

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:

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

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:
