Title:
Exception should be raised if nova has failed to add fixed ip
Status in OpenStack Compute (nova):
Invalid
Bug description:
I have the following code
try:
instance.add_fixed_ip(network.id)
except Exception as e:
...
The issue is that in Nova compute logs I can see exception, but it is not
thrown on client side.
Since add_fixed_ip() returns nothing, it is difficult to find if fixed
address was assigned.
Exception:

This exception, most probably, was caused by dhcp agent failing to find tap
device:
"""
Stderr: 'Cannot find device "tap41e55d74-72"\n'
"""
The device indeed was missing, but after I restarted all services, it
did not appear.
I use Icehouse.
