[2.5] Event logging breaks when an IP is assigned to multiple interfaces with the same MAC

[Mike Pontillo]

When deploying KVM using the checkbox in the UI, a bridge is automatically created, and every time I deploy I see tracebacks in the log such as the following:

This is happening because the event logging code assumes that only one Node will ever be found from the following query:

        node = Node.objects.get(
            interface__ip_addresses__ip=ip_address)

This isn't quite correct, but for a non-obvious reason: this query can return the same node more than once.
