[Bug 1021810] Re: `nova-manage fixed list` fails if network has been deleted

[Tong Li]

The problem is that in nova-manage, the code catches
exception.NetworkNotFound and blindly say "Command failed, please check
log for more info" regardless what the exception might be.

With latest code as July 17, 2012,  in the scenario you described, the
following command will both produce that error.

with latest code, July 17, 2012,

$nova-manage fixed list
