Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1898994 Title: bandwidth resource allocation is deleted from placement during unrelated port update Status in neutron: Fix Released Bug description: Neutron deletes the bandwidth resource allocation in placement if the port is updated even though the qos policy of the port is not changed. Reproduction: 1) Create a all in one devstack deployment from master 2) Create qos a port with qos min bandwidth policy openstack network create net0 \ --provider-network-type vlan \ --provider-physical-network physnet0 \ --provider-segment 100 \ ## openstack subnet create subnet0 \ --network net0 \ --subnet-range 10.0.4.0/24 \ ## openstack network qos policy create qp0 openstack network qos rule create qp0 \ --type minimum-bandwidth \ --min-kbps 1000 \ --egress \ ## openstack network qos rule create qp0 \ --type minimum-bandwidth \ --min-kbps 1000 \ --ingress \ ## openstack port create port-normal-qos \ --network net0 \ --vnic-type normal \ --qos-policy qp0 \ ## 3) Boot a server with that port openstack --os-compute-api-version 2.80 server create --flavor c1 --image cirros-0.5.1-x86_64-disk --nic port-id=port-normal-qos vm1 --wait 4) Check the resource allocation of the server in placement openstack resource provider allocation show cf5809b6-1dbe-43d5-8270-b734255a946e +--------------------------------------+------------+--------------------------------------------------------------------------+ | resource_provider | generation | resources | +--------------------------------------+------------+--------------------------------------------------------------------------+ | 1110cf59-cabf-526c-bacc-08baabbac692 | 13 | {'NET_BW_EGR_KILOBIT_PER_SEC': 1000, 'NET_BW_IGR_KILOBIT_PER_SEC': 1000} | | 7b122d5c-02cd-499c-a415-c07029498010 | 21 | {'VCPU': 1, 'MEMORY_MB': 256, 'DISK_GB': 1} | +--------------------------------------+------------+--------------------------------------------------------------------------+ 5) Update the description of the port openstack port set --description "this is my port" port-normal-qos 6) Check the resource allocation again openstack resource provider allocation show cf5809b6-1dbe-43d5-8270-b734255a946e +--------------------------------------+------------+---------------------------------------------+ | resource_provider | generation | resources | +--------------------------------------+------------+---------------------------------------------+ | 7b122d5c-02cd-499c-a415-c07029498010 | 22 | {'VCPU': 1, 'MEMORY_MB': 256, 'DISK_GB': 1} | +--------------------------------------+------------+---------------------------------------------+ Expected behavior: The resource allocation is not changed during description update Actual behavior: The bandwidth resource allocation is deleted in placement Note that changing the binding:profile also has the same effect, but changing the name of the port does not trigger the same problem.
