UUID already exists
VirtualBox adds the old vdi file to the new system and will report: UUID already exists.
Recreate the uuid:
Cd C:\ Program Files\ Oracle\ VirtualBox\ VBoxManage.exe internalcommands sethduuid x:\ path\ xxx.vdi
Command description:
Usage: VBoxManage internalcommands [command arguments] Commands: loadmap [module] [subtrahend] [segment] This will instruct DBGF to load the given map file during initialization. (See also loadmap in the debugger.) Loadsyms [delta] [module] [module address] This will instruct DBGF to load the given symbol file during initialization. Sethduuid [] Assigns a new UUID to the given image file. This way, multiple copies of a container can be registered. Sethdparentuuid Assigns a new parent UUID to the given image file. Dumphdinfo Prints information about the image at the given location. Listpartitions-rawdisk Lists all partitions on. Createrawvmdk-filename-rawdisk [- partitions [- mbr]] [- relative] Creates a new VMDK image which gives access to an entire host disk (if the parameter-partitions is not specified) or some partitions of a host disk. If access to individual partitions is granted, then the parameter-mbr can be used to specify an alternative MBR to be used (the partitioning information in the MBR file is ignored). The diskname is on Linux e.g. / dev/sda, and on Windows e.g.\.\ PhysicalDrive0). On Linux or FreeBSD host the parameter-relative causes a VMDK file to be created which refers to individual partitions instead to the entire disk. The necessary partition numbers can be queried with VBoxManage internalcommands listpartitions renamevmdk-from-to Renames an existing VMDK image, including the base file and all its extents. Converttoraw [- format] Convert image toraw, writing to file. Converthd [- srcformat VDI | VMDK | VHD | RAW] [- dstformat VDI | VMDK | VHD | RAW] converts hard disk images between formats repairhd [- dry-run] [- format VDI | VMDK | VHD |.] Tries to repair corrupted disk images modinstall Installs the necessary driver for the host OS moduninstall Deinstalls the driver debuglog [--enable |-- disable] [--flags todo] [--groups todo] [--destinations todo] Controls debug logging. Passwordhash Generates a password hash. Gueststats [--interval] Obtains and prints internal guest statistics. Sets the update interval if specified.
