Flavor
Templates - named flavors - are predefined for virtual machines.
You can find flavors list by using openstack flavor list command.
$ openstack flavor list

These flavors provide the necessary material resources such as
- disks size
- memory
- core number
which will define the computing capacity of the instance to create..
Be careful, don’t choose a flavor that exceeds the remaining available resources.
For example :
On this image, the icons indicate that the template requires a too large resource compared to the remaining available resources.
Then, the instance cannot be built with these templates.
