Public bug reported:

Using Horizon I try to launch an instance with 2 networks defined.

The operation fails with the following error:
ERROR nova.scheduler.filter_scheduler [req-cae61024-6723-4218-bd5e-71b42d181cea admin demo] [instance: 54c6f9ba-57e5-4680-bb6b-72eb2da484db] Error from last host: devstack-vmware1 (node devstack-vmware1): [u'Traceback (most recent call last):

Looks like there is a None event in the events map.

When  I  launch an instance with 1 network defined I face no issues.
