Public bug reported:
When adding a qos policy to a network or port, there is the following check in
the qos_plugin:
# minimum-bandwidth rule is only supported (independently of
# drivers) on networks whose first segment is backed by a physnet
if rule.rule_type == qos_consts.RULE_TYPE_MINIMUM_BANDWIDTH:
net = network_object.Network.get_object(
context, id=port.network_id)
physnet = net.segments[0].physical_network
if physnet is None:
raise qos_exc.QosRuleNotSupported(rule_type=rule.rule_type,
port_id=port['id'])
To my knowledge this statement is simply untrue as it is precisly the reference
drivers which have this problem, not necessarily all drivers. This blocks me
from creating a qos_driver that does support mimimum bandwidth without a
physnet.
The same goes for min_bw_rule_updates when the port is bound.
I propose we move those checks to the qos_drivers themselves.
