Flavor
Templates - named flavors - are predefined for virtual machines.
You can find flavors list by using openstack flavor list command.
Beware, two namespaces coexist. Flavors whose names start with m1 or m0 are obsolete

These flavors describe the resources allocated to an instance:
- disks size
- memory
- core number
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.
