Public bug reported:
Description
===========
Resizing an instance with swap to a flavor without swap, the instance won't run
because libvirt will still look after a swap file, for exemple, the
default_swap_device in nova/instances table is still set to /dev/vdb after
resizing.
The XML passed to libvirt still have the swap device defined.
Steps to reproduce
==================
* Create an instance with Swap
* Resize instance to a flavor without swap
* Try to start instance
Expected result
===============
The instance start without swap
Actual result
=============
Error in nova log
OSError: [Errno 2] No such file or directory:
'/var/lib/nova/instances/66035f60-6e17-4f09-bb00-885e3cc5750f/disk.swap'
libvirt xml still have the swap defined
