Manage flavors

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.
|
|
|
|
As of Newton, there are no default flavors. The following table
|
|
lists the default flavors for Mitaka and earlier.

**Dashboard — Create Flavor**
|
|
|
|
========================= =======================================
|
|
**Name** Enter the flavor name.
|
|
**ID** Unique ID (integer or UUID) for the
|
|
new flavor. If specifying 'auto', a
|
|
UUID will be automatically generated.
|
|
**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 lifecycle
|
|
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.
|
|
**RX/TX Factor** Optional property allows servers with
|
|
a different bandwidth to be created
|
|
with the RX/TX Factor. The default
|
|
value is 1. That is, the new bandwidth
|
|
is the same as that of the attached
|
|
network.
|
|
========================= =======================================

|
|
#. 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
|
|
use the flavor. If there are no projects in the right column,
|
|
all projects can use the flavor.
|
|
#. Click :guilabel:`Create Flavor`.
