Title:
Rescheduled boot from volume instances fail due to the premature
removal of their attachments
Status in OpenStack Compute (nova):
In Progress
Status in OpenStack Compute (nova) queens series:

Bug description:
Description
===========
This is caused by the cleanup code within the compute layer
(_shutdown_instance) removing all volume attachments associated with an
instance with no attempt being made to recreate these ahead of the instance
being rescheduled.
Steps to reproduce
==================
- Attempt to boot an instance with volumes attached.
- Ensure spawn() fails, for example by stopping the l2 network agent services
on the compute host.
Expected result
===============
The instance is reschedule to another compute host and boots correctly.
Actual result
=============
The instance fails to boot on all hosts that is rescheduled to due to a
missing volume attachment.
Environment
===========
1. Exact version of OpenStack you are running. See the following
list for all releases: http://docs.openstack.org/releases/
bf497cc47497d3a5603bf60de652054ac5ae1993
2. Which hypervisor did you use?
(For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
What's the version of that?
Libvirt + KVM, however this shouldn't matter.
3. Which storage type did you use?
(For example: Ceph, LVM, GPFS, ...)
What's the version of that?
N/A
4. Which networking type did you use?
(For example: nova-network, Neutron with OpenVSwitch, ...)
N/A
