Public bug reported:

When a request is made to boot an instance from a volume and a volume is
passed in as part of the request, rather than an image to have Nova
create a volume from, the image id is not passed down as part of the
build request.  The boot_meta dict created in compute/api.py does not
store an 'id' key/value in the dict so when it eventually gets down to
the virt layer and the dict is converted to an object the 'id' attribute
can not be accessed.  This causes a failure within the xenapi driver.

Title:
  xenapi boot from volume is broken after move to ImageMeta object if
  volume passed in

Status in OpenStack Compute (nova):
  In Progress

Bug description:
  When a request is made to boot an instance from a volume and a volume
  is passed in as part of the request, rather than an image to have Nova
  create a volume from, the image id is not passed down as part of the
  build request.  The boot_meta dict created in compute/api.py does not
  store an 'id' key/value in the dict so when it eventually gets down to
  the virt layer and the dict is converted to an object the 'id'
  attribute can not be accessed.  This causes a failure within the
  xenapi driver.
