> Believing virtualization always makes things slower is a mistake. Well, virtualization does make everything slower. It's just that the boot process ends up quite fast as the virtual machine usually has a much less (and simpler) hardware to initialize at boot, has a simpler BIOS/UEFI, and shorter if any power-on self test. A physical machine can be made to those specs - Intel has done <2s boot from power is applied till a graphical application is visible and fully interactive for automotive back in 2019.
