Как конвертировать образы между virtualbox и qemu/kvm

Все преобразования происходят через формат raw:

из vdi в raw:

VBoxManage internalcommands converttoraw image.vdi image.raw

из raw в qcow:

qemu-img convert -f raw image.raw -O qcow2 image.qcow

Assume your VirtualBox image is called “ubuntu.vdi”

Step 1. Convert the VB disk vdi image to a raw image format.

VBoxManage clonehd --format RAW ubuntu.vdi ubuntu.img

Note: The ubunut.img is a raw disk image, it will be quite large (as many GB as your virtual drive is, see above).

Step 2 : convert the raw image to a qcow

qemu-img convert -f raw ubuntu.img -O qcow2 ubuntu.qcow

That is all there is to it, the ubuntu.qcow can be used with KVM.

Test your new image (ubuntu.qcow) with:

kvm -m 512 -usbdevice tablet -hda ubuntu.qcow

If it is working you may delete the raw image (ubuntu.img) and archive or delete the ubuntu.vdi .

Welcome to KVM :)
