E.g. tenant_network_types = vlan,gre,vxlan

I was told this let user to create different network types for the tenants.

However, I don’t see the option to specify the network type when creating a network.

localadmin@qa4:~/devstack$ neutron help net-create
usage: neutron net-create [-h] [-f {shell,table,value}] [-c COLUMN]
                          [--max-width <integer>] [--prefix PREFIX]
                          [--request-format {json,xml}]
                          [--tenant-id TENANT_ID] [--admin-state-down]
                          [--shared]
                          NAME

Is it possible to have VM1 of tenant 1 uses VLAN, and VM1 of tenant2 uses GRE; when both VMs reside at the same compute node?
