1. Adding the meta-rauc-qemu layer to your build

Run

bitbake-layers add-layer meta-rauc-qemu

2. Use systemd-boot

Add to local.conf:

# systemd-boot version
MACHINE_FEATURES_append = " pcbios efi"
DISTRO_FEATURES_append = " efi"
IMAGE_FSTYPES += "wic"
WKS_FILE = "qemux86-systemd-boot-efi.wks"
EFI_PROVIDER = "systemd-boot"
IMAGE_INSTALL_append = " \
                systemd-boot \
                efibootmgr \
"
EXTRA_IMAGEDEPENDS += "ovmf"

# Only use systemd as init
DISTRO_FEATURES_append = " systemd"
DISTRO_FEATURES_remove = "sysvinit"
DISTRO_FEATURES_BACKFILL_CONSIDERED_append = " sysvinit"
VIRTUAL-RUNTIME_initscripts = ""
VIRTUAL-RUNTIME_syslog = ""
VIRTUAL-RUNTIME_init_manager = "systemd"

# Install ssh server
IMAGE_INSTALL_append = " dropbear"

# Install RAUC
IMAGE_INSTALL_append = " rauc"

Start qemu with:

runqemu wic nographic ovmf

3. Use Grub

Add to local.conf:

MACHINE ?= "qemux86-64"
MACHINE_FEATURES += "pcbios efi"
IMAGE_FSTYPES += "wic"
WKS_FILE = "qemux86-grub-efi.wks"
EFI_PROVIDER = "grub-efi"
IMAGE_INSTALL_append = " \
                grub \
                grub-efi \
"
EXTRA_IMAGEDEPENDS += "ovmf"
PREFERRED_RPROVIDER_virtual/grub-bootconf = "rauc-qemu-grubconf"

Start qemu with:

runqemu wic nographic ovmf
