Title:
  libvirt inject_data assumes instance with kernel_id doesn't contain a
  partition table

Status in OpenStack Compute (nova):
  In Progress

Bug description:
  libvirt/driver.py passes partition=None to disk.inject_data() for any
  instance with kernel_id set. partition=None means that inject_data
  will attempt to mount the whole image, i.e. assuming there is no
  partition table. While this may be true for EC2, it is not safe to
  assume that Xen images don't contain partition tables. This should
  check something more directly related to the disk image. In fact,
  ideally it would leave it up to libguestfs to work it out, as
  libguestfs is very good at this.
