====== VirtualBox KVM ======

Converting VirtualBox VM (VDI format) to KVM (qcow2 format):

<code>
#list available VirtualBox HDDs and note Capacity and Location
VBoxManage list hdds

#Convert VDI to RAW image
VBoxManage clonehd --format RAW /home/wuff/VirtualBoxVMs/Win10/Win10.vdi win10.img

#Convert RAW image to qcow2 image
qemu-img convert -f raw win10.img -O qcow2 win10.qcow2
