Ah so looks like this is actually fixed in icehouse - we just need to
backport it to Havana. See https://bugs.launchpad.net/nova/+bug/1255449
and the related fix.

Let me close this is a dublicate of that - and I will propose a backport
for havana stable there.

Title:
  nova overwrites hw_disk_bus image property with incorrect value

Status in OpenStack Compute (Nova):
  Triaged

Bug description:
  Currently using Havana

  Booting from a snapshot with the image property 'hw_disk_bus' = ide
  boots fine initially. Shutting down/restarting the instance via the
  dashboard overwrites this value with 'virtio' in the libvirt.xml
  definition. The value in glance and nova image is correct.
