# It's important to convert the vbox image (VMDK or VDI or whatever) using
# the same version of VirtualBox that created it. You can try converting the image
# with qemu-img or kvm-img, but weird version mismatches will possibly make it not
# work.

# On your VirtualBox machine:

cd $VBOX_ROOT/$MACHINE_ROOT/
VBoxManage clonehd machine.vmdk machine.img --format RAW
scp machine.img root@kvm-host:/somewhere
