Public bug reported:

Description
===========

"Virtual device tagged attach"(*1) has been added in microversion 2.49.
After attaching the interface by using this function, detaching the interface from the server does not work properly.
So attaching the interface again fails.

*1: https://blueprints.launchpad.net/nova/+spec/virt-device-tagged-
attach-detach

Steps to reproduce
==================

1. attach an interface (neutron port) to a server with tag
2. detach the interface from the server
   The following message is logged in nova-compute.log.

   TypeError: _delete_nic_metadata() takes exactly 3 arguments (4 given)

3. attach the interface (neutron port) to the server again
   HTTP 500 returns.
   <class 'VirtualInterfaceCreateException_Remote'> (HTTP 500) (Request-ID: req-5c369d01-e2f2-4cba-97a9-84fba8e240af)
