Title:
Create vm then detach interface immediately leaves the port in BUILD
status
Status in neutron:
Expired
Bug description:
You can reproduce the bug as below：
Create one vm and then detach the interface of this vm immediately.
But be notice that the bug is hard to reproduce because it depends on the
indeed handling sequence.
In the sequences descripted bellow,the bug happens:
1, create one vm and the nova-compute notify neutron using the "port_create"
api,and nova create one port for ovs.
2, neutron-server created the related detail information in the db.
3.1, ovs-agent aware the creation of the port by loop function and start to
handle the "port_add" event. It gets the details of the port from neutron
server correctly in the treat_devices_added_or_updated function, but the
function "get_vif_port_by_id" has not been called.
4, detach the interface of the vm and the nova will delete the port of ovs
3.2 when "get_vif_port_by_id" is excuting, it find the vif not exists and
skips.
5, then the port will be leave BUILD and will can not be operated by
end-users forever.
You can make the reproduction of the bug easy by calling "time.sleep(5)"
after the plugin_rpc.get_devices_details_list in
treat_devices_added_or_updated function,and when sleep is happening ,detach the
interface from vm.
