This command creates a new medium. The syntax is as follows:

VBoxManage createmedium     [disk|dvd|floppy]    --filename <filename>
                            [--size <megabytes>|--sizebyte <bytes>]
                            [--diffparent <uuid>|<filename>
                            [--format VDI|VMDK|VHD] (default: VDI)
                            [--variant Standard,Fixed,Split2G,Stream,ESX]

The parameters are as follows:

--filename <filename>

Specifies a file name <filename> as an absolute path on the host file system. Mandatory.

--size <megabytes>

Specifies the image capacity, in 1 MB units. Optional.

--diffparent <uuid>|<filename>

Specifies the differencing image parent, either as a UUID or by the absolute pathname of the file on the host file system. Useful for sharing a base box disk image among several VMs.

--format VDI|VMDK|VHD

Specifies the file format for the output file. Available options are VDI, VMDK, VHD. The default format is VDI. Optional.

--variant

Specifies any required file format variants for the output file. This is a comma-separated list of variant flags. Options are Standard,Fixed,Split2G,Stream,ESX. Not all combinations are supported, and specifying mutually incompatible flags results in an error message. Optional.

Note

For compatibility with earlier versions of Oracle VM VirtualBox, the createvdi and createhd commands are also supported and mapped internally to the createmedium command.
