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.
Flavor | VCPUs | Disk (in GB) | RAM (in MB) |

project from the drop-down list.In the
Admin
tab, open theSystem
tab and click theFlavors
category.Click
Create Flavor
.In the
Create Flavor
window, enter or select the parameters for the flavor in theFlavor Information
tab.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
Flavor Access
tab, you can control access to the flavor by moving projects from theAll Projects
column to theSelected Projects
column.Only projects in the
Selected Projects
column can use the flavor. If there are no projects in the right column, all projects can use the flavor.Click
