Matt Riedemann ade6c93936 Handle Invalid exceptions as expected in attach_interface
The bug prompting this is a tempest test which is requesting
a port attachment to a server but not specifying a port or
network to use, so nova-compute looks for a valid network
and finds there are two and raises NetworkAmbiguous. This
is treated as a 400 error in the API but because this is a
synchronous RPC call from nova-api to nova-compute,
oslo.messaging logs an exception traceback for the unexpected
error. That traceback is pretty gross in the compute logs for
something that is a user error and the cloud operator has
nothing to do to fix it.

We can handle the traceback by registering our expected
exceptions for the attach_interface method with oslo.messaging,
which is what this change does.

While looking to just add NetworkAmbiguous it became clear that
lots of different user errors can be raised from this method
and none of those should result in a traceback, so this change
just expects Invalid and its subclasses.

The one exception is InterfaceAttachFailed which is raised when
something in allocate_port_for_instance or driver.attach_interface
fails. That is an unexpected situation so the parent class for
InterfaceAttachFailed is changed from Invalid to NovaException so
it continues to be traced in the logs as an exception.
InterfaceAttachFailedNoNetwork is kept as Invalid since it is a
user error (trying to attach an interface when the user has no
access to any networks).

test_tagged_attach_interface_raises is adjusted to show the
ExpectedException handling for one of the Invalid cases.

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:
