I'm not actually sure if the RPIs have hardware virtualization extensions, though I'm not sure what your trying to do but perhaps containerization would work as well? That or BSD Jails. Those don't require any additional hardware features and use the same kernel allowing for more efficient use of memory. The only limitation is that you must use an OS capable of using the same kernel your running. https://linuxcontainers.org/ NetBSD 9.x also works great on the RPIs. That's what I run on mine. Perhaps you could just swap out the sdcard from one with NetBSD aarch64 to try it bare metal? Being with how cheap RPI computers and sdcards are. https://wiki.netbsd.org/ports/aarch64/ -- _____________________________________ / An editor is one who separates the \ | wheat from the chaff and prints the | | chaff. | | | \ -- Adlai Stevenson / ------------------------------------- \ \ /\ /\ //\\_//\\ ____ \_ _/ / / / * * \ /^^^] \_\O/_/ [ ] / \_ [ / \ \_ / / [ [ / \/ _/ _[ [ \ /_/ _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
