I got another doubt, how do I instance a VM through the terminal with a
desired tenant in a desired network? When I run nova boot --flavor x
--image x --key_name x --security_groups x vm-name it starts with admin
tenant on my ext_network (that contains my floating_ip), but I want the VM
with internal_network IP and after set up a floating ip.
Thank you.
