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.

The following table lists the default flavors.

Create flavors

  1. Log in to the dashboard.

    Choose the admin project from the drop-down list at the top of the page.

  2. In the Admin tab, open the System Panel and click the Flavors category.

  3. Click Create Flavor.

  4. In the Create Flavor window, enter or select the parameters for the flavor.

    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.

  5. In the Flavor Access tab, you can control access to the flavor by moving projects from the All Projects column to the Selected 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.

  6. Click Create Flavor.
