Just to make sure there wasn't something odd going on, I reproduced this test using the standard alpine ISO just now using -current: # vmctl start test -i 1 -d /home/mlarkin/Downloads/alpine-standard-3.6.2-x86_64.iso -d test.raw -m 1024M -c At the boot: prompt, I used: boot: hardened console=ttyS0,115200 Alpine then booted as follows: [ 0.000000] ACPI BIOS Error (bug): A valid RSDP was not found (20160831/tbxfroot-244) [ 0.086666] ACPI BIOS Error (bug): A valid RSDP was not found (20160831/tbxfroot-244) [ 0.089999] dmi: Firmware registration failed.

[ ok ] Welcome to Alpine Linux 3.6 Kernel 4.9.32-0-hardened on an x86_64 (/dev/ttyS0) localhost login: root Welcome to Alpine! The Alpine Wiki contains a large amount of how-to guides and general information about administrating Alpine systems. See <http://wiki.alpinelinux.org>. You can setup the system with the command: setup-alpine You may change this message by editing /etc/motd. localhost:~# ... I then went on to install the system using setup-alpine and the docs from the alpine web site. No issues were seen, and the system booted up subsequently without the ISO (of course, after setting serial console in the boot config). I am going to pull down a snapshot and retest to see if there is something that may have snuck in that's not in my tree. -ml
