diskimage_builder build redhat7 cannot boot

[Xiwen Deng]

I have a ironic env and want to build some bare metal image. I use diskimage_builder to build a redhat7 image that support lvm, the redhat7 image build successed. But when bare-metal boot from this image, cannot find bootloader.

diskimage-builder command is follow:
disk-image-create rhel7 vm devuser disable-selinux dhcp-all-interfaces dracut-regenerate -o redhat7

export DIB_BLOCK_DEVICE_CONFIG='
- local_loop:
    name: image0

- partitioning:
    base: image0
    label: mbr
    partitions:
      - name: root
        flags: [ boot,primary ]
        size: 100%

    base: [root]
    pvs:
      - name: pv
        options: ["--force"]

    mount:
      mount_point: /home
      fstab:

Have you tried updating kernel and kernel-firmware packages?
