* 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.
*
* After balancing the code size and the complied code size,
* I put my solution here. The v1 and v2 is a version specified
* code, which only be generated for first four version. The v3
* will be put in vbox_common.c, it be complied only once, then
* be used by all next vbox drivers.
*
* Check the flag vboxAttachDrivesUseOld can tell you which
* implementation to use. When the flag is set, we need use
* the old version though gVBoxAPI.vboxAttachDrivesOld. It

* If the flag is clear, just call vboxAttachDrivesNew, which

* 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.
