 A basic virtual machine for SEAPATH based on debian can be created using the https://github.com/seapath/build_debian_iso#build-a-virtual-machine-image[build_debian_iso] repository.
 
+You can also create a yocto VM using the flavour cqfd _guest_efi_, as described in the https://github.com/seapath/yocto-bsp[yocto-bsp] repository, in the following way:
+
+ $ cqfd -b guest_efi
+
 To deploy this machine on the cluster, follow these steps :
 - Place the generated qcow2 file in the `vm_images` directory with the name `guest.qcow2`.
 - Create an inventory describing your virtual machines. An example can be found in `examples/inventories`
