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 and delete flavors and update their
metadata.

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

Create flavors

  1. Log in to the Dashboard and select the admin project from the
    drop-down list.

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

  3. Click Create Flavor.

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

    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.

  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.

Update Metadata

  1. Log in to the Dashboard and select the admin project from the
    drop-down list.

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

  3. Select the flavor that you want to update. In the drop-down list,
    click Update Metadata or click No or Yes in the Metadata
    column.

  4. In the Update Flavor Metadata window, you can customize
    some metadata keys, then add it to this flavor and set them
    values.

  5. Click Save.

    Optional metadata keys

    CPU limits quota:cpu_shares
    quota:cpu_period
    quota:cpu_limit
    quota:cpu_reservation
    quota:cpu_quota
    Disk tuning quota:disk_read_bytes_sec
    quota:disk_read_iops_sec
    quota:disk_write_bytes_sec
    quota:disk_write_iops_sec
    quota:disk_total_bytes_sec
    quota:disk_total_iops_sec
    Bandwidth I/O quota:vif_inbound_average
    quota:vif_inbound_burst
    quota:vif_inbound_peak
    quota:vif_outbound_average
    quota:vif_outbound_burst
    quota:vif_outbound_peak
    Watchdog behavior hw:watchdog_action
    Random-number generator hw_rng:allowed
    hw_rng:rate_bytes
    hw_rng:rate_period

    For information about supporting metadata keys, see the the Compute
    service documentation.

Delete flavors
