Install - automatically


i have managed to connect to my VCD ( vmware cloud ) , and create virtual machine , load iso file and all other resources that I need.

I need help with this: How can I , once the machine is created, start the automatic installation of the OS (Debian, centos, suse…) ?

I don’t want them to just power on and wait for me to do a manual setup of the machine, I want to do that automatically. Basically, when I open it, I just want to see the login screen and the machine is ready to be used.
