Disk and container formats for images
|
|
=====================================
|
|
|
|
When you add an image to the Image service, you can specify
|
|
its disk and container formats.
|
|
|
|
Disk formats
|
|
~~~~~~~~~~~~
|
|
|
|
The disk format of a virtual machine image is the format of the
|
|
underlying disk image.
|
|
Virtual appliance vendors have different formats for laying out
|
|
the information contained in a virtual machine disk image.
|
|
|
|
Set the disk format for your image to one of the following values:
|
|
|
|
aki
|
|
An Amazon kernel image.
|
|
ami
|
|
An Amazon machine image.
|
|
ari
|
|
An Amazon ramdisk image.
|
|
iso
|
|
An archive format for the data contents of an optical disc,
|
|
such as CD-ROM.
|
|
qcow2
|
|
Supported by the QEMU emulator that can expand dynamically
|
|
and supports Copy on Write.
|
|
raw
|
|
An unstructured disk image format; if you have a file
|
|
without an extension it is possibly a raw format.
|
|
vdi
|
|
Supported by VirtualBox virtual machine monitor and the QEMU emulator.
|
|
vhd
|
|
The VHD disk format, a common disk format used by virtual
|
|
machine monitors from VMware, Xen, Microsoft, VirtualBox, and others.
|
|
vmdk
|
|
Common disk format supported by many common virtual machine monitors.
|
|
|
|
Container formats
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
The container format indicates whether the virtual machine image is in
|
|
a file format that also contains metadata about the actual virtual machine.
|
|
|
|
.. note::
|
|
|
|
The Image service and other OpenStack projects do not currently
|
|
support the container format. It is safe to specify ``bare`` as
|
|
the container format if you are unsure.
|
|
|
|
You can set the container format for your image to one of the following
|
|
values:
|
|
|
|
aki
|
|
An Amazon kernel image.
|
|
ami
|
|
An Amazon machine image.
|
|
ari
|
|
An Amazon ramdisk image.
|
|
bare
|
|
The image does not have a container or metadata envelope.
|
|
docker
|
|
A docker container format.
|
|
ovf
|
|
The OVF container format.
