not update request_spec.request_networks after attach or detach interface

[yangyegang]

i attach a port to vm ,but request_spec.request_networks did not update. port_id of request_spec.request_networks is null.

"request_networks": {
   "nova_object.version": "1.1",
   "nova_object.changes": ["objects"],
   "nova_object.name": "NetworkRequestList",
   "nova_object.data": {
    "objects": [{
     "nova_object.version": "1.2",
     "nova_object.changes": ["network_id", "pci_request_id", "tag", "port_id", "address"],

      "network_id": "90ba0584-b2b7-4f6a-b862-f77864d8626f",

hi, after created instance and attach interface using servers/{server_id}/os-interface api i could not any information related with the request_networks in the request_specs table (nova_api database).
Can you help me to reproduce the same ??

[yangyegang (yang-yegang)]

i hope request_spec.request_networks.network_id is null after detach all port.but ,now the network_id still exist.
you can detach all ports of instance to reproduce it.

[Deepak Mourya (mourya007)]

i have detached all the ports from the instance , but where did you find the request_spec.request_networks.network_id .

 openstack server list
+--------------------------------------+---------+--------+----------+--------------------------+---------+
| ID | Name | Status | Networks | Image | Flavor |

+--------------------------------------+---------+--------+----------+--------------------------+---------+
for this result , yes network is removed.

can you locate me the request_spec.request_networks ?

[yangyegang (yang-yegang)]

you can see the network_id in the value spec of request_specs table( nova-api database). after detach all port the network_id should be null i think,but it not change.

[Deepak Mourya (mourya007)]

Steps i have performed for the same :

1. created Vm and then detach all ports from the same.
2. use nova_api database ;
3. use request_specs table

But i could not get anything term related with network_id , port etc.

Note : i have checked this in Queen and Pike both.

[yangyegang (yang-yegang)]

network_id should be null after detach all ports.but it is not.
"nova_object.data": {
                          "network_id": "90ba0584-b2b7-4f6a-b862-f77864d8626f",

[Deepak Mourya (mourya007)]

Can you please share me your environment details where you are suing this (openstack version). ?

[yangyegang (yang-yegang)]

my openstack version is pike

[Deepak Mourya (mourya007)]

I have performed some steps to reproduce the same , correct me where something is missing:

Note : pike version

1. Detach port from the VM.

+--------------------------------------+------+--------+----------+--------------------------+---------+

2. Select * from request_specs ;
I could not get the requisite network object here. I have attached the output of my table.

[Deepak Mourya (mourya007)]

I have use Pike Version of openstack and the checked the same but request_specs table cannot include requested_network .

 request_specs
[RequestSpec(availability_zone=None,flavor=Flavor(6),force_hosts=None,force_nodes=None,id=12,ignore_hosts=None,image=ImageMeta(8913ec9e-0378-4284-a795-165536d9d986),instance_group=None,instance_uuid=a2db5724-fc08-467b-922d-60e9d86fdf24,limits=SchedulerLimits,num_instances=1,numa_topology=None,pci_requests=InstancePCIRequests,project_id='cb4b235dc1b94e65b3f99a15f5418a7e',requested_destination=None,retry=None,scheduler_hints={},security_groups=SecurityGroupList)]

May be this is why network is not there.

[yangyegang (yang-yegang)]

i reproduce it,after i detach posrt, spec of request_sepcs table still have information of network_id(e2a254e5-7cbc-4cd5-8766-d3403156a937). i think network_id should be null after all ports of net be detached.

[yangyegang (yang-yegang)]

I checked Pike version andthe version of my environment. the pike really have no request_network。You can ignore this problem。 I'm sorry

[Matt Riedemann (mriedem)]

The request spec is to track the initial server create request, not to be a complete mirror of everything that has ever happened to the instance, like when volumes and ports are attached to it.

I don't see how this is a bug - what end-user issue do you have as a result of this?

[Deepak Mourya (mourya007)]

Yes , recently i have also checked this bug on the master branch but could not find the result as per the issue specified here.
