Matt Riedemann 05cd8d1282 Fix InstanceNotFound during _destroy_evacuated_instances
The _destroy_evacuated_instances method on compute
startup tries to cleanup guests on the hypervisor and
allocations held against that compute node resource
provider by evacuated instances, but doesn't take into
account that those evacuated instances could have been
deleted in the meantime which leads to a lazy-load
InstanceNotFound error that kills the startup of the
compute service.

This change does two things in the _destroy_evacuated_instances
method:

1. Loads the evacuated instances with a read_deleted='yes'
   context when calling _get_instances_on_driver(). This
   should be fine since _get_instances_on_driver() is already
   returning deleted instances anyway (InstanceList.get_by_filters
   defaults to read deleted instances unless the filters tell
   it otherwise - which we don't in this case). This is needed
   so that things like driver.destroy() don't raise
   InstanceNotFound while lazy-loading fields on the instance.

2. Skips the call to remove_allocation_from_compute() if the
   evacuated instance is already deleted. If the instance is
   already deleted, its allocations should have been cleaned
   up by its hosting compute service (or the API).

The functional regression test is updated to show the bug is
now fixed.

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:
