 @abstract Initialize the disk attachment from a file handle.
 @param fileHandle File handle to a block device.
 @param readOnly If YES, the disk attachment is read only, otherwise, if the file handle allows writes, the device can write data into it.
 @param synchronizationMode Defines how the disk synchronizes with the underlying storage when the guest operating system flushes data.
 @param error If not nil, assigned with the error if the initialization failed.
 @return An initialized `VZDiskBlockDeviceStorageDeviceAttachment` or nil if there was an error.
 @discussion
    The file handle is retained by the disk attachment.
    The handle must be open when the virtual machine starts.

    The `readOnly` parameter affects how the disk is exposed to the guest operating system
    by the storage controller. If the disk is intended to be used read-only, it is also recommended
    to open the file handle as read-only.
