Virtualize in multiple TTY (VT*)

I want to get virtual machine in a TTY (VT*) in fullscreen like GDM3 can take a TTY (VT*) for the graphic part of linux I want DISPLAY (heard as the output of a graphic server, here the VMs) to be redirected in a TTY (VT*), and not in a window like usually It will make like the computer run multiple OS at the same time but in fact it's a Linux Kernel who virtualize the differents OS that we can see on the different TTY (VT*) You know, the TTY (VT*) in CTRL + ALT + Fi ---------- Okay ---------- Not okay
