     * vbox versions. In sight of implementation, the v1 is
     * totally different with v2 and v3. The v2 shares the same
     * outline with v3, meanwhile the API they used has much
     * difference.
     *
     * It seems we have no thing to do with old versions such as
     * v1 and v2 when developing new vbox drivers. What's more,
     * most of the vbox APIs used in v1 and v2 is incompatible with
     * new vbox versions. It is a burden to put these APIs into
     * vboxUniformedAPI, I prefer not to do that.

     * the machine settings path.
     * Then, if the machine current snapshot xml file is saved in the machine location,
     * it means that this snapshot was previously modified by us and has fake disks.
     * Fake disks are added when the flag VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT was not set
     * yet, in order to not corrupt read-only disks. The first thing to do is to remove those
     * disks and restore the read-write disks, if any, in the vboxSnapshotXmlMachinePtr struct.
     * We also delete the current snapshot xml file.
     *
     * After that, we are going to register the snapshot read-only disks that we want to redefine,
     * if they are not in the media registry struct.
     *
     * The next step is to unregister the machine and close all disks.
     *
     * Then, we check if the flag VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE has already been set.
     * If this flag was set, we just add read-write disks to the media registry
     * struct. Otherwise, we save the snapshot xml file into the machine location in order
     * to recover the read-write disks during the next redefine and we create differential disks
     * from the snapshot read-only disks and add them to the media registry struct.
     *
     * Finally, we register the machine with the new virtualbox description file.
