<title>VBoxManage: VDI (VirtualBox) to raw</title>
|
|
<para>If you've created a VDI image using VirtualBox, you can convert it to raw format using
|
|
the <command>VBoxManage</command> command-line tool that ships with VirtualBox. On Mac
|
|
OS X, VirtualBox stores images by default in the <filename>~/VirtualBox VMs/</filename>
|
|
directory. The following example creates a raw image in the current directory from a
|
|
VirtualBox VDI
|
|
image.<screen><prompt>$</prompt> <userinput>VBoxManage clonehd ~/VirtualBox\ VMs/fedora18.vdi fedora18.img --format raw</userinput></screen></para>
