VBoxManage clonehd
This command duplicates a registered virtual hard disk image to a new image file with a new unique identifier (UUID). The new image can be transferred to another host system or imported into VirtualBox again using the Virtual Media Manager; see the section called ?The Virtual Media Manager? and the section called ?Cloning disk images?. The syntax is as follows:
VBoxManage clonehd |
[--format VDI|VMDK|VHD|RAW|]
[--variant Standard,Fixed,Split2G,Stream,ESX]
[--type normal|writethrough|immutable]
[--remember]
where the parameters mean:
format
Allow to choose a file format for the output file different from the file format of the input file.
variant
Allow to choose a file format variant for the output file. It is a comma-separated list of variant flags. Not all combinations are supported, and specifying inconsistent flags will result in an error message.
type
Only honored if --remember is also specified. Defines what kind of hard disk type this image should be.
remember
Keep the destination image registered after it was successfully written.
