Deploy PNETLab on Google cloud

[PJ777]

Help!  I tried settling up Pnetlab with :

gcloud compute images create nested-ubuntu-xenial --source-image-family=ubuntu-1804-lts --source-image-project=ubuntu-os-cloud --licenses https://www.googleapis.com/compute/v1/projects/vm-options/global/licenses/enable-vmx

but i kept getting error messages ..

ERROR: (gcloud.compute.images.create) argument --licenses: expected one argument
Usage: gcloud compute images create IMAGE_NAME (--source-disk=SOURCE_DISK | --source-image=SOURCE_IMAGE | --source-image-family=SOURCE_IMAGE_FAMILY | --source-snapshot=SOURCE_SNAPSHOT | --source-uri=SOURCE_URI) [optional flags]

For detailed information on this command and its flags, run:

Please help.
