### Using existing flavors (OpenStack only)



Typically, OSM creates the flavors needed by the VDUs, which are specified by the `virtual-compute-desc` parameter in the VNFD. In some cases, flavors must contain a complex EPA configuration that is not supported by descriptors, so they need to be created manually in the VIM beforehand.



An existing flavor can be used by passing it's ID to `vim-flavor-id` at the VDU level. The following example shows the syntax:



```yaml

--config '{vnf: [ {member-vnf-index: "vnf", vdu: [ {id: hackfest_basic-VM, vim-flavor-id: "O1.medium" } ] } ] }'

```
