Bug description:
  Once the glance image from which an instance was spawned is deleted,
  resizes of that image fail if they would take place across more than
  one compute node. Migration and live block migration both succeed.

  Resize fails, I believe, because 'qemu-img resize' is called
  
(https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L7218-L7221)
  before the backing image has been transferred from the source compute
  node
  
(https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L7230-L7233).

  Replication requires two compute nodes. To replicate:

  1. Boot an instance from an image or snapshot.
  2. Delete the image from Glance.
  3. Resize the instance. It will fail with an error similar to:

  Stderr: u"qemu-img: Could not open '/var/lib/nova/instances/f77f1c5c-
  71f7-4645-afa1-dd30bacef874/disk': Could not open backing file: Could
  not open
  '/var/lib/nova/instances/_base/ca94b18d94077894f4ccbaafb1881a90225f1224':

2016-03-21 Thread Matt Riedemann 
There is a backport proposed to stable/kilo but I don't think we should
take it since the original fix for this introduced a regression which we
are having to fix on master, stable/mitaka and stable/liberty now. I'd
rather not deal with that in stable/kilo too.

libvirt: Fix resize of instance with deleted glance image

finish_migration() in the libvirt driver was attempting to resize an
image before checking that its backing file was present. This patch
re-orders these 2 operations. In doing so, we also have to resolve an
overloading of the 'disk_info' variable.

Closes-Bug: #1546778
