WIC Image Installer

Note

Only EFI compatible systems are currently supported by the image installer (e.g. intel-corei7-64).

To generate a WIC based image installer, switch the default WKS_FILE_sota definition for your target machine to image-efi-installer.wks:

$ cat meta-subscriber-overrides/conf/machine/include/lmp-factory-custom.inc
WKS_FILE_intel-corei7-64_sota = "image-efi-installer.wks.in"

As WIC is only capable of consuming one single WKS file (even if multiple are defined via WKS_FILES), this will force the build system to only generate installer images by default.

Remove the custom WKS_FILE_sota override to restore back to the default behavior and generate normal bootable WIC images

Testing WIC Image Installer with Qemu (x86)

It is possible to test the WIC image installer with Qemu, all that is required is an additional block device with enough disk space for the LMP rootfs image.

If running Qemu without graphics support, make sure that the default console is set to ttyS0,115200, which can be done manually in grub (by editing the boot arguments before booting the install target) or by removing console=tty0 from the image installer by changing lmp-factory-custom.inc:

$ cat meta-subscriber-overrides/conf/machine/include/lmp-factory-custom.inc
APPEND_remove_intel-corei7-64 = "console=tty0"

Create the virtual disk device that will be used as target with qemu-img:

$ qemu-img create -f raw disk.img 4G

Download lmp-factory-image-intel-corei7-64.wic and ovmf.qcow2 from your own Factory CI run, then run Qemu with the following arguments:

$ qemu-system-x86_64 -device virtio-net-pci,netdev=net0,mac=52:54:00:12:35:02 \
    -netdev user,id=net0,hostfwd=tcp::2222-:22 \
    -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0 \
    -drive if=none,id=hd,file=lmp-factory-image-intel-corei7-64.wic,format=raw \
    -device virtio-scsi-pci,id=scsi -device scsi-hd,drive=hd \
    -drive if=none,id=hd2,file=disk.img,format=raw -device scsi-hd,drive=hd2 \
    -drive if=pflash,format=qcow2,file=ovmf.qcow2 -no-reboot \
    -nographic -cpu kvm64 -enable-kvm -m 1024 -serial mon:stdio -serial null

Now just follow the instructions provided by the installer in order to install the actual LMP image into disk.img.

After completed, hit enter to stop the current Qemu execution and start it up again, but using disk.img as the primary block device:

$ qemu-system-x86_64 -device virtio-net-pci,netdev=net0,mac=52:54:00:12:35:02 \
    -netdev user,id=net0,hostfwd=tcp::2222-:22 \
    -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0 \
    -drive if=none,id=hd,file=disk.img,format=raw \
    -device virtio-scsi-pci,id=scsi -device scsi-hd,drive=hd \
    -drive if=pflash,format=qcow2,file=ovmf.qcow2 \
    -nographic -cpu kvm64 -enable-kvm -m 1024 -serial mon:stdio -serial null
