qemu-img convert: raw, qcow2, qed, vdi, vmdk, vhd<\/h2>\n

The qemu-img convert<\/strong> command can do conversion between multiple formats, including qcow2<\/span><\/code>, qed<\/span><\/code>, raw<\/span><\/code>, vdi<\/span><\/code>, vhd<\/span><\/code>, and vmdk<\/span><\/code>.<\/p>\n\n\n\n<\/colgroup>\n\n\n\n\n\n\n\n\n\n

This example will convert a raw image file named image.img<\/span><\/code> to a qcow2 image file.<\/p>\n

\n
\n
$<\/span> qemu-img convert -f raw -O qcow2 image.img image.qcow2\r\n<\/pre>\n<\/div>\n<\/div>\n
Run the following command to convert a vmdk image file to a raw image file.<\/p>\n
\n
\n
$<\/span> qemu-img convert -f vmdk -O raw image.vmdk image.img\r\n<\/pre>\n<\/div>\n<\/div>\n
Run the following command to convert a vmdk image file to a qcow2 image file.<\/p>\n
\n
\n
$<\/span> qemu-img convert -f vmdk -O qcow2 image.vmdk image.qcow2\r\n<\/pre>\n<\/div>\n<\/div>\n
\n
<\/div>\n
NoteThe -f<\/span> format<\/span><\/code> flag is optional. If omitted, qemu-img<\/span><\/code> will try to infer the image format.<\/p>\n
When converting an image file with Windows, ensure the virtio driver is installed. Otherwise, you will get a blue screen when launching the image due to lack of the virtio driver. Another option is to set the image properties as below when you update the image in the Image service to avoid this issue, but it will reduce virtual machine performance significantly.<\/p>\n

VBoxManage: VDI (VirtualBox) to raw<\/h2>\n
If you\u2019ve created a VDI image using VirtualBox, you can convert it to raw format using the VBoxManage<\/span><\/code> command-line tool that ships with VirtualBox. On Mac OS X, and Linux, VirtualBox stores images by default in the ~\/VirtualBox<\/span> VMs\/<\/span><\/code> directory. The following example creates a raw image in the current directory from a VirtualBox VDI image.<\/p>\n
\n

$<\/span> VBoxManage clonehd ~\/VirtualBox\\ <\/span>VMs\/image.vdi image.img --format raw<\/pre>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
