Debian on OpenBSD vmd (without qemu or another debian system)

boot.img.gz - prepared boot image

Setup

vmd(8) config, need working network and internet connection.

/etc/vm.conf

ROOT="/home/debian"
vm "debianinstall" {
	disable
	memory 1024M
	disk $ROOT/boot.img
	disk $ROOT/disk0.raw
	interface { switch "uplink" }
	owner debian
}
vm "debian" {
	disable
	memory 1024M
	disk $ROOT/disk0.raw
	interface { switch "uplink" }
	owner debian
}
switch "uplink" {
	interface bridge0
}

Preparation of install media

Use the hd-boot image with a patched xen initrd. Adding virtio modules to the ramdisk. Switching the bootloader to serial console mode.

cd ..

doas mount /dev/vnd1i /mnt
doas cp initrd.gz /mnt/INITRD.GZ
doas vi /mnt/TXT.CFG

	+	append vga=off initrd=initrd.gz --- quiet console=ttyS0,115200n8 ^M
doas umount /mnt
doas vnconfig -u vnd1

Starting the install

In the bootloader use the text install. Need to load the virtio modules first before starting the install procedure.

vmctl start debianinstall -c
	Grub -> Install
	Installer -> Press ESC -> Execute a shell
		depmod
		modprobe virtio_pci virtio_blk
		lsmod
		exit
	Continue install

First boot

Most probably need to edit the boot entry because /dev/vdb has changed to /dev/vda. Also the network card changed name from enp0s4 to enp0s3.
