SYNOPSIS

openstack flavor command [options]

openstack flavor manages instance flavors (size templates) in OpenStack Nova. Flavors define compute, memory and storage resources for virtual machines. Properties set via --property (aka extraspecs) control scheduler and hypervisor behavior — common keys include `hw:cpupolicy`, `hw:mempagesize`, `hw:numanodes`, `quota:diskreadbytessec` and `aggregateinstanceextra_specs:*`. The set command can also add or remove tenant access for private flavors via `--project` / `--project-domain`.Part of OpenStack unified CLI (`python-openstackclient`), superseding the old `nova flavor-*` commands.

PARAMETERS

list

List available flavors.

show name

Show flavor details.

create name

Create flavor.

delete name

Delete flavor.

set name

Set flavor properties.

--vcpus num

Number of vCPUs.

--ram mb

RAM in megabytes.

--disk gb

Root disk size in gigabytes.

--ephemeral gb

Ephemeral disk size in gigabytes (default: 0).

--swap mb

Swap space size in megabytes (default: 0).

--id id

Unique flavor ID ('auto' generates a UUID, default: auto).

--public

Make flavor accessible to all projects (default).

--private

Make flavor accessible only to specific projects.

--property key=value

Set extra specification property on the flavor.

CAVEATS

Modifying a flavor is not possible in-place: change a property via set/unset, or delete and recreate for size changes. Running instances continue to use the original flavor. Admin role is required for create/delete and for setting most properties.
