module' object has no attribute 'instance_by'

Using the latest Nova folsom builds I'm seeing the following exceptions from Nova network.log:

    Use instance_get instead of instance_by.

    Updates the network manager to use db.instance_get instead of
    db.instance_by (which doesn't exist). This change seems to have
    slipped in in the recent vifs UUID conversion code.

    Fixes LP Bug #1031756.
