Problem description

If an image for VirtualBox is build two files are created: a .vmx with the machine description, and a .vmdk, the virtual machine disk image. The vmdk is unpacked, resulting in a 3.6GB download.
packing it reduced the size to 1.2GB.

It would be good if the result bundler take both (vmx and vmdk) and group them together in
one compressed archive

If you install the ovftool and build an OVA file it is automatically compressed.

yes which we do if the format is set to ova. However we support the following format:

  • gce (raw disk and manifest in compressed archive)
  • ova (compressed)
  • qcow2 (compressed)
  • vagrant (for libvirt provider, raw disk and manifest in compressed tarball, box file)
  • vmdk (uncompressed)
  • vdi (I think uncompressed)
  • vhd (uncompressed)
  • vhdx (compressed)
  • vhd-fixed (uncompressed)

For any of the types which are uncompressed I think the kiwi result bundle call should compress the result. This means the bundle provides the image in a not directly consumable form for the target system but I think a decompression step before is better to handle than the transfer of GB of data

Change bundling of image formats
18ba277 
By default none of the image formats were stored as compressed
file. The reason behind this was the assumption that some
formats automatically makes use of compression, which is true
but only in their processing and not in their data blocks at
creation time. Storage and handling of the image file itself
becomes cumbersome and therefore we change the default bundle
setup for image formats to be compressed. This means the image
as it gets packed by KIWI needs to be uncompressed before use.
The following image formats are affected by the change in a
call of the result bundler:

    kiwi result bundle ...

    * qcow2 (.qcow2.xz)
    * vdi   (.vdi.xz)
    * vhd   (.vhd.xz)
    * vhdx  (.vhdx.xz)
    * vmdk  (.vmdk.xz)

All other image formats already defined a custom bundling
setup including compression and are not affected by this change.
This Fixes #650
