The Exception notification code calls inspect.trace(), which returns an
empty list if called outside of an except clause. The returned list is
then indexed, causing an IndexError. In fact, every use of this
exception in the engine is from outside of an except clause.
This can affect notification processing, causing notifications to get
stuck in a running state, requiring manual DB deletion.
This change addresses the issue by checking whether the list returned by
inspect.trace() is empty.
A more complete solution would involve checking every call path to the
exception notification, and ensuring that it is made from an except
clause.

Masakari
Virtual Machine High Availability (VMHA) service for OpenStack
Masakari provides Virtual Machine High Availability (VMHA) service for OpenStack clouds by automatically recovering the KVM-based Virtual Machine(VM)s from failure events such as VM process down, provisioning process down, and nova-compute host failure. It also provides API service for manage and control the automated rescue mechanism.
NOTE: Use masakari only if instance path is configured on shared storage system i.e, 'instances_path' config option of nova has a path of shared directory otherwise instance data will be lost after the evacuation of instance from failed host if, * instance is booted from image * flavor using ephemeral disks is used
