wic images are handled as vmtype images. Starting qemu with "-kernel" parameter and an image of type wic is not supported. Especially for "-machine virt" the combination of wic with -kernel parameter would be beneficial. The new parameter QB_FSINFO allows to pass image type specific flags to runqemu. QB_FSINFO is a space separated list of parameters. Parameters are structured according to the following pattern: image-type:flag. For now two parameters are supported: - wic:no-kernel-in-fs The wic image is treated as rootfs only image. A -kernel option is passed to qemu. - wic:kernel-in-fs The wic image is treated as VM image including a bootloader and a kernel. This is still the default behavior. Example: QB_DEFAULT_FSTYPE = "wic" QB_FSINFO = "wic:no-kernel-in-fs" QB_KERNEL_ROOT = "/dev/vda1" QB_SYSTEM_NAME = "qemu-system-aarch64" QB_MACHINE = "-machine virt" ...

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
