Install 9front in OpenBSD VMM

This guide explains how to install 9front as a virtual machine inside OpenBSD's VMM https://wiki.ircnow.org/Vmm.Intro

Download the ISO

This installation assumes you (or your admin) has configured VMM https://wiki.ircnow.org/Vmm.Intro properly.

Inside your home folder, download the 9front ISO:

$ ftp https://9front.org/iso/9front-10522.amd64.iso.gz $ sha256 9front-10522.amd64.iso.gz SHA256 (9front-10522.amd64.iso.gz) = 89f1e35bf735bfc9aeca38286a9a6607f3a40292befa4a30133157790f2edbcc 89f1e35bf735bfc9aeca38286a9a6607f3a40292befa4a30133157790f2edbcc 9front-10522.amd64.iso.gz $ gunzip 9front-10522.amd64.iso.gz $ ln -sf 9front-10522.amd64.iso $USER.iso

Inside /etc/vm.conf, make sure your virtual machine's cdrom is set to $USER.iso:

vm "$USER" { owner $USER memory 2048M cdrom "/home/$USER/$USER.iso" disk /home/$USER/$USER.qcow2 interface { locked lladdr aa:bb:cc:dd:ee:ff switch "switch0" } }

Stop your existing virtual machine:

$ vmctl stop $USER

You may need to delete any existing data, then create a new qcow2 image, then start the virtual machine:

$ rm $USER.qcow2 $ vmctl create -s 20G $USER.qcow2 $ vmctl start -c $USER Connected to /dev/ttyp9 (speed 115200) Boot failed: not a bootable disk

At this point, you must immediately interrupt booting to type console=0:

>console=0 ccoonnssoollee==00

Then type boot:

If you use the Windows NT/2000/XP master boot record or a master boot record from a Unix clone (e.g., LILO or FreeBSD bootmgr), it is probably safe to continue using that boot record rather than install the Plan 9 boot record.

Install the Plan 9 master boot record (yes, no)no default: yes Mark the Plan 9 partition active (yes, no)no default: yes

The Plan 9 partition is now marked as active.

The following unfinished tasks are ready to be done: finish - finish the installation and reboot

Task to do finish:

At this point, plan9 is unable to reboot on its own. We escape the serial console, then stop and restart the machine. First, type ~~. then:

$ doas vmctl stop $USER $ doas vmctl start -c $USER
