Description Cristian Muresanu 2019-09-05 17:39:11 UTC 
Description of problem:

Attempting to delete instance doesn't work:
> openstack server delete 5bb9b8ea-831d-4cf4-9e3f-dfeaf1b70c73

Seems cannot delete because it has a parent port for a trunk, and can't delete the trunk because it's in use.

Hi, we're wondering if there is any chance for this issue to be resolved in osp13z9 update ?
Thanks,
Cristian
Comment 4 Freddy Wissing 2019-12-19 14:40:04 UTC 
Realizing this isn't high priority, is there any estimate when this could be looked at?

Thank you,

Comment 6 Nate Johnston 2020-01-24 22:46:33 UTC 
Freddy and Cristian,

Can you check on something for me?  First, please paste the output of "openstack network trunk show <port-id>" where the port-id is the id of the port of the instance that cannot be deleted.

Second, if you see attached subports in the output, please loop over them and run "openstack network trunk unset --subport <subport-id> <port-id>" for each.  Then see if the instance can be deleted.

Thanks!
