@stefano for some reason, every time I've tried getting Alpine vms to work on FreeBSD they fail to boot because they can't find the kernel, both with your blog post settings and with the default profile (I was using vm-bhyve at the time). Eventually I gave up and tried Debian, and it worked right away. Never managed to figure out why though.
@linus I'm now using UEFI and that is quite reliable. I've had the same problem with some old Alpine Linux releases
