如何使用meta-intel生成可在VMware启动的Yocto core-image-minimal ISO镜像

我尝试使用meta-intel层生成core-image-minimal的ISO镜像，镜像生成过程无报错，但在VMware中启动失败（启动时无法找到有效引导项）。

以下是我的local.conf配置：

MACHINE  ?= "intel-corei7-64"
#
# This sets the default machine to be qemux86-64 if no other machine is selected:
MACHINE ??= "qemux86-64"
DISTRO ?= "poky"
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats"


IMAGE_FSTYPES += "live"
NOISO = "0"

PREFERRED_PROVIDER_virtual/kernel = "linux-intel"

DEPENDS:append:${MACHINE} = " cdrtools-native"


IMAGE_FSTYPES:append = " ext4"
IMAGE_TYPEDEP_wic = "ext4"
do_image_wic[depends] += "${INITRD_IMAGE_LIVE}:do_image_complete"
do_rootfs[depends] += "virtual/kernel:do_deploy"

IMAGE_BOOT_FILES:append = "\
  ${KERNEL_IMAGETYPE} \
  microcode.cpio \
  ${IMGDEPLOYDIR}/${IMAGE_BASENAME}-${MACHINE}.ext4;rootfs.img \
  ${@bb.utils.contains('EFI_PROVIDER', 'grub-efi', 'grub-efi- bootx64.efi;EFI/BOOT/bootx64.efi', '', d)} \
  ${@bb.utils.contains('EFI_PROVIDER', 'grub-efi', '${IMAGE_ROOTFS}/boot/EFI/BOOT/grub.cfg;EFI/BOOT/grub.cfg', '', d)} \
  ${@bb.utils.contains('EFI_PROVIDER', 'systemd-boot', 'systemd-bootx64.efi;EFI/BOOT/bootx64.efi', '', d)} \
  ${@bb.utils.contains('EFI_PROVIDER', 'systemd-boot', '${IMAGE_ROOTFS}/boot/loader/loader.conf;loader/loader.conf ', '', d)} \
  ${@bb.utils.contains('EFI_PROVIDER', 'systemd-boot', '${IMAGE_ROOTFS}/boot/loader/entries/boot.conf;loader/entries/boot.conf', '', d)} "

bblayers.conf配置：

POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /home/brain/poky/meta \
  /home/brain/poky/meta-poky \
  /home/brain/poky/meta-yocto-bsp \
  /home/brain/poky/meta-intel\
  "

请问如何生成可在VMware正常启动的ISO镜像？

针对VMware启动失败的问题，可通过以下调整修复：

1. 明确指定MACHINE配置 #

删除MACHINE ??= "qemux86-64"，仅保留MACHINE = "intel-corei7-64"，避免机器架构配置混淆：

MACHINE = "intel-corei7-64"
DISTRO ?= "poky"
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
USER_CLASSES ?= "buildstats"

2. 修正IMAGE_BOOT_FILES的错误配置 #

• 移除grub-efi- bootx64.efi中的多余空格，改为grub-efi-bootx64.efi
• 由于intel-corei7-64默认使用grub-efi作为EFI引导器，可简化配置，无需兼容systemd-boot：

IMAGE_BOOT_FILES:append = "\
  ${KERNEL_IMAGETYPE} \
  microcode.cpio \
  ${IMGDEPLOYDIR}/${IMAGE_BASENAME}-${MACHINE}.ext4;rootfs.img \
  grub-efi-bootx64.efi;EFI/BOOT/bootx64.efi \
  ${IMAGE_ROOTFS}/boot/EFI/BOOT/grub.cfg;EFI/BOOT/grub.cfg \
"

3. 确保live镜像包含必要的引导组件 #

在EXTRA_IMAGE_FEATURES中添加live-boot，保证live镜像具备完整的启动能力：

EXTRA_IMAGE_FEATURES ?= "debug-tweaks live-boot"

4. 调整ISO生成的依赖与参数 #

• 替换cdrtools-native为genisoimage-native（部分Yocto版本中cdrtools-native兼容性较差）：

DEPENDS:append:${MACHINE} = " genisoimage-native"

• 明确ISO生成参数：

NOISO = "0"
IMAGE_FSTYPES += "iso live"

5. 启用VMware相关内核驱动 #

确保linux-intel内核包含VMware所需驱动，添加以下配置强制开启：

KERNEL_FEATURES:append = " features/virtualization/virtualization.scc"

6. 重新构建镜像 #

执行以下命令清理并重新构建：

bitbake -c cleanall core-image-minimal
bitbake core-image-minimal
