Converting images from one format to another is generally straightforward.
Install qemu-utils
(ubuntu) : apt-get install qemu-utils
qemu-img convert: raw, qcow2, VDI, VMDK
The qemu-img convert command can do conversion between multiple formats, including raw, qcow2, VDI (VirtualBox), VMDK (VMware) and VHD (Hyper-V).
Image format | Argument to qemu-img |
|---|---|
raw | raw |
qcow2 | qcow2 |
VDI (VirtualBox) | vdi |
VMDK (VMware) | vmdk |
VHD (Hyper-V) | vpc |
This example will convert a raw image file named centos63.dsk to a qcow2 image file.
$ qemu-img convert -f raw -O qcow2 centos64.dsk centos64.qcow2
To convert from vmdk to raw, you would do:
$ qemu-img convert -f vmdk -O raw centos64.vmdk centos64.img
to convert from vdi to raw, you can do:
qemu-img convert -f vdi -O raw clovr-standard-2012-11-16-20-05-15.vdi clovr.img
To convert from vdi to qcow2:
qemu-img convert -f vdi -O qcow2 clovr-standard-2012-11-16-20-05-15.vdi clovr-standard-2012-11-16-20-05-15.qcow2
