Convert VirtualBox .vdi image to qcow2

We needed to convert .vdi image created on VirtialBox hiperviser to qcow2 format for use with KVM. Below are steps that we took to get it done.
1. Convert vdi to raw disk image

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

2. On KVM host we can now convert it to qcow2

qemu-img convert -f raw vmimage.img -O qcow2 vmimage.qcow2
