Public bug reported:

Description
===========
Nova is currently unable to create and then boot from volumes from encrypted volume snapshots when the original volume_type is not provided as part of the block_device_mapping request to n-api. Failure to provide this will result in the following error when attempting to launch the instance:

Details: {'code': 500, 'created': '2019-11-21T16:56:58Z', 'message':
'Build of instance 176ff71f-1dff-433b-92c7-5a15bade375f aborted: Invalid
input received: Invalid input received: Invalid volume_type provided:
9142150e-70fe-4b14-942f-015025de4a68 (requested type is not compatible;
recommend omitting the type argument). (H'}"

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

* Create an encrypted volume snapshot
* Attempt to create an instance based on this without providing a volume_type in the block_device_mapping.

Expected result
===============
Nova copies the original volume_type if one is not provided in the request.

Actual result
=============
Nova fails to copy the original volume_type leading to a failure when attempting to create a volume based on the encrypted volume snapshot as the types do not match.

Environment
===========
1. Exact version of OpenStack you are running. See the following
  list for all releases: http://docs.openstack.org/releases/

   master

2. Which hypervisor did you use?
   (For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
   What's the version of that?

   Libvirt + KVM

2. Which storage type did you use?
   (For example: Ceph, LVM, GPFS, ...)
   What's the version of that?

   N/A

3. Which networking type did you use?
   (For example: nova-network, Neutron with OpenVSwitch, ...)

   N/A
