Have you set up dual boot with Linux and FreeBSD on an x86-64/amd64 system? If so, please describe. > While it‘s possible to run one operating system as guest inside of the another operating system, this approach has got several disadvantages. > If you want to test operating systems, a starting point to do this is using persistent live media. For example, copy several Linux live ISO to a Ventoy USB-stick and make them persistent and get NomadBSD. Testing an operating system as guest in a virtual machine suffers from the limits of the virtualization, especially when using VirtualBox, let alone that anything hardware related depends on the host‘s drivers, hence you can‘t experience hardware support of the guest. For hardware support testing, I agree that a live CD can be useful. For evaluating FreeBSD support of specific hardware, I would try the FreeBSD installer "Live CD" option (see Figure 3): https://docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-start NomadBSD advertises "automatic hardware detection and setup", which might conceal potential problems with a genuine FreeBSD installation. For OS and software evaluation, an advantage of a (supported) VM is that there should be few, if any, device driver issues (e.g. virtual hardware is known and supported). This allows you focus on FreeBSD, vscode, etc.. For example, I have a VM with FreeBSD 12.3-RELEASE-p6 GENERIC amd64 that is running on VirtualBox 6.1.38 on Debian 11.5 Linux 5.10.0-18-amd64. I see one error message via dmesg(8): 2022-09-28 22:21:19 toor@vf1 ~ # dmesg | grep -i error module_register_init: MOD_LOAD (vesa, 0xffffffff811848b0, 0) error 19 AIUI "vesa" is an X Windows driver. I access the VM via ssh(1) and have not installed X, so the error message does not concern me. David
