Manage flavors In OpenStack, a flavor defines the compute, memory, and storage capacity of a virtual server that users can launch. As an administrative user, you can create, edit, and delete flavors. Only administrative users can create and manage flavors. A flavor consists of the following parameters:
Flavor parameters
Parameter Description
Flavor Name The flavor name.
VCPUs Number of virtual CPUs to use.
RAM Amount of RAM to use, in megabytes.
Root Disk Amount of disk space (in gigabytes) to use for the root (/) partition.
Ephemeral Disk 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 Amount of swap space (in megabytes) to use. If unspecified, the default is 0.
ID The flavor ID, generated by OpenStack.
The default flavors are: m1.tiny (1 VCPU/0 GB Disk/512 MB RAM) m1.small (1 VCPU/20 GB Disk/2048 MB RAM) m1.medium (2 VCPU/40 GB Disk/4096 MB RAM) m1.large (4 VCPU/80 GB Disk/8192 MB RAM) m1.xlarge (8 VCPU/160 GB Disk/16384 MB RAM)
Create flavors Log in to the dashboard. Choose the admin project from the CURRENT PROJECT drop-down list. On the Admin tab, click the Flavors category. Click Create Flavor. In the Create Flavor window, enter or select the following values: Name Enter the flavor name. 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 mount 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 GB Enter the amount of swap space (in megabytes) to use. If unspecified, the default is 0. Click Create Flavor.
Update flavors Log in to the dashboard. Choose the admin project from the CURRENT PROJECT drop-down list. On the Admin tab, click the Flavors category. Select the flavor that you want to edit. Click Edit Flavor. In the Edit Flavor window, you can change the flavor name, VCPUs, RAM, root dish, ephemeral disk, and swap disk values.. Click Save.
Delete flavors Log in to the dashboard. Choose the admin project from the CURRENT PROJECT drop-down list. On the Admin tab, click the Flavors category. Select the flavors that you want to delete. Click Delete Flavors. In the Confirm Delete Flavors window, click Delete Flavors to confirm the deletion. You cannot undo this action.
