In OpenStack, a flavor defines the compute, memory, and storage
|
|
capacity of a virtual server, also known as an instance. As an
|
|
administrative user, you can create, edit, and delete flavors.
|
|
|
|
The following table lists the default flavors.

Choose the :guilabel:`admin` project from the drop-down
|
|
list at the top of the page.
|
|
#. In the :guilabel:`Admin` tab, open the :guilabel:`System
|
|
Panel` and click the :guilabel:`Flavors` category.

**Flavor info tab**
|
|
|
|
======================= =========================================
|
|
**Name** Enter the flavor name.
|
|
**ID** OpenStack generates the flavor ID.
|
|
**VCPUs** Enter the number of virtual CPUs to
|
|
use.
|
|
**RAM MB** Enter the amount of RAM to use, in
|
|
megabytes.
|
|
**Root Disk GB** Enter the amount of disk space in
|
|
gigabytes to use for the root (/)
|
|
partition.
|
|
**Ephemeral Disk GB** Enter the amount of disk space in
|
|
gigabytes to use for the ephemeral
|
|
partition. If unspecified, the value
|
|
is 0 by default.
|
|
|
|
Ephemeral disks offer machine local
|
|
disk storage linked to the life cycle
|
|
of a VM instance. When a VM is
|
|
terminated, all data on the ephemeral
|
|
disk is lost. Ephemeral disks are not
|
|
included in any snapshots.
|
|
**Swap Disk MB** Enter the amount of swap space (in
|
|
megabytes) to use. If unspecified,
|
|
the default is 0.

#. In the :guilabel:`Flavor Access` tab, you can control access to
|
|
the flavor by moving projects from the :guilabel:`All Projects`
|
|
column to the :guilabel:`Selected Projects` column.
|
|
|
|
Only projects in the :guilabel:`Selected Projects` column can
