I will take a look at this

[Steve Kowalik (stevenk)]

That doesn't look like a DIB issue. Are you sure your kernel has "Device mapper support" enabled as either a built-in or a module?

    Update to newer Centos7 images

    Update to newer Centos7 images as announced at [1].

    Changes included:
     * update to GA image
     * respect TMP_DIR for image working directory
     * use suffix-match rather than prefix-match to build RAW_IMAGE name
       to be more robust against weird names
     * partition layout work-arounds not needed any-more, all one
       partition.

    Resulting image booted locally with kvm and virtualbox (after
    conversion to vdi)
