Dear users,

I am getting problem while creating an instance . Its stuck at scheduling phase

I have noticed when i restart nova compute service , it restarted successfully BUT It logs error on nova-compute.log

2019-11-30 06:29:30.324 145061 ERROR nova.compute.resource_tracker [req-6a4d7b4f-9ab1-4669-8c7e-99e3adb5cb18 - - - - -] Skipping removal of allocations for deleted instances: Failed to retrieve allocations for resource provider 27a39914-a509-4261-90f5-8135ad471843:

1) nova.conf is not changed , It just the same which comes with the distribution

2) Openstack overall health seems OK, all services are in running state

3) Problem : placement url running on port 8778 ( URL : http://<ip address="" &gt;:8778="" placement="" )="" is="" showing="" internal="" server="" error="" (500)="" while="" accessing="" via="" web="" browser="" or="" curl="" .<="" p="">

4) nova-status upgrade check also showing error InternalServerError: Internal Server Error (HTTP 500)

5) followed the standard method of installation described in https://www.rdoproject.org/install/packstack/ (https://www.rdoproject.org/install/pa...)

6) I have pasted o/p of log during a nove compute service restart and nova service status

Appreciate all your help

Thanks Bipul

Please check network details neutron net-show <id>

Check for network_type, physical_network, segmentation_id all are correctly mapped , Verified same is being used in neutron.conf you are using ovs only for port creation?

Thanks for the response. update output of net-show in the question, I am using very basic network only for instance creation . Just created a network and subnet , Nothing changed in neutron.conf.

how many physical server you have ? you are using admin tenant to create new instance? verify if "geneve" is mapped to correct interface on server

UPDATE :

While investigating more on logs , i found that there is a permission issue on file

chmod 777 /var/log/nova/nova-placement-api.log

and restart httpd service resolve the URL issue and nova-status upgrade now shows everything successful .

However , Instance creation still stuck at scheduling with below log 

  2019-12-01 01:16:13.410 31934 INFO nova.api.openstack.placement.requestlog [req-c9a2982a-5397-4bfb-bab4-39ae1c6493c5 a826d1b4b465467eaee8b13d9832ab5c 60533b189d5647d2abc4cbdd3ee79c69 - default default] 10.5.87.31 "GET /placement/resource_providers/27a39914-a509-4261-90f5-8135ad471843/allocations" status: 200 len: 54 microversion: 1.0

requests are just logging in with different ID's , Status 200 (So it seems success response ) But it stuck at scheduling phase of creation and ERROR out with a timeout mesg

Kindly help

Port binding errors usually occur when you created a port as admin user, maybe even in the admin project, and you try to attach it to an instance in a different project. Try to re-create the port with openstack port create ... --project <PROJECT_ID>.

if it's not too late try checking openstack port list if your port is active: also check if yor nic interface is connected to neutron linuxbridge interface
