    A big set of changes to how we create XEN guest disks. · fbc26aea

    Prior to this commit, XEN guests disks were single partition, no MBR,
    the bits dumped into the lvm. This makes a snapshot of a XEN node,
    look completely different then a physical disk image, especially if
    users want more disk space (mkextrafs) inside the guest, and then want
    to take a snapshot of that, and then run it on a physical node (which
    was not possible).
    With these changes, guests now use the same MBR layout as our version
    two MBR, which makes them interchangeable with physical disk images.
    In fact, the goal is to be able to switch back and forth as needed,
    based on physical resource availability.
