Public bug reported:

When we install OS in a VM created by an ISO image, it was failed.

Steps to reproduce:
1.  create an ISO image,   glance image-create --name ubuntu.iso --disk-format iso --container-format bare  --file ubuntu-14.04.2-server-amd64.iso --progress
2. create a vm using this ISO image
3. install OS in this vm.

We think the nova generates wrong libvirt config, below are two examples:
1.  For a vm with local storage,  it can't detect disk when install OS.  The partial libvirt.xml is as follow:

<devices>
  <disk type="file" device="cdrom">
    <driver name="qemu" type="qcow2" cache="none"/>
    <source file="/opt/stack/data/nova/instances/9b3c730a-8391-4b11-8e07-dcd0981fbc56/disk"/>
    <target bus="ide" dev="hda"/>
  </disk>
  <disk type="file" device="cdrom">
    <driver name="qemu" type="raw" cache="none"/>
    <source file="/opt/stack/data/nova/instances/9b3c730a-8391-4b11-8e07-dcd0981fbc56/disk.config"/>
    <target bus="ide" dev="hdd"/>
  </disk>

2. For a volume vm,  it can't detect CD-ROM when install OS. And the
partial libvirt.xml is as follow:

<devices>
  <disk type="file" device="disk">
    <driver name="qemu" type="qcow2" cache="none"/>
    <source file="/var/lib/nova/instances/95a38caf-9f12-4516-8166-6c5b572b4734/disk"/>
    <target bus="virtio" dev="vda"/>
  </disk>
  <disk type="file" device="disk">
    <driver name="qemu" type="raw" cache="none"/>
    <source file="/var/lib/nova/instances/95a38caf-9f12-4516-8166-6c5b572b4734/disk.config"/>
    <target bus="virtio" dev="vdz"/>
  </disk>

Title:
  OS install failed in the VM created using an ISO image

Status in OpenStack Compute (Nova):
  New

Bug description:
  When we install OS in a VM created by an ISO image, it was failed.

  Steps to reproduce:
  1.  create an ISO image,   glance image-create --name ubuntu.iso --disk-format iso --container-format bare  --file ubuntu-14.04.2-server-amd64.iso --progress
  2. create a vm using this ISO image
  3. install OS in this vm.

  We think the nova generates wrong libvirt config, below are two examples:
  1.  For a vm with local storage,  it can't detect disk when install OS.  The partial libvirt.xml is as follow:

  <devices>
    <disk type="file" device="cdrom">
      <driver name="qemu" type="qcow2" cache="none"/>
      <source file="/opt/stack/data/nova/instances/9b3c730a-8391-4b11-8e07-dcd0981fbc56/disk"/>
      <target bus="ide" dev="hda"/>
    </disk>
    <disk type="file" device="cdrom">
      <driver name="qemu" type="raw" cache="none"/>
      <source file="/opt/stack/data/nova/instances/9b3c730a-8391-4b11-8e07-dcd0981fbc56/disk.config"/>
      <target bus="ide" dev="hdd"/>
    </disk>

  2. For a volume vm,  it can't detect CD-ROM when install OS. And the
  partial libvirt.xml is as follow:

  <devices>
    <disk type="file" device="disk">
      <driver name="qemu" type="qcow2" cache="none"/>
      <source file="/var/lib/nova/instances/95a38caf-9f12-4516-8166-6c5b572b4734/disk"/>
      <target bus="virtio" dev="vda"/>
    </disk>
    <disk type="file" device="disk">
      <driver name="qemu" type="raw" cache="none"/>
      <source file="/var/lib/nova/instances/95a38caf-9f12-4516-8166-6c5b572b4734/disk.config"/>
      <target bus="virtio" dev="vdz"/>
    </disk>
