Solution 1

We are going to use qemu-img tool to this.QEMU disk image utility

First Install qemu  qemu-img is included with qemu package using the following command

sudo apt-get install qemu

Convert a VMWare Image to VirtualBox Image

Convert VMWare image called whatever.vmdk to /tmp/debian.bin (or a path of your choice).

qemu-img convert debian.vmdk /tmp/debian.bin

Now use VBoxManage to get back image in native format:

VBoxManage convertdd /tmp/debian.bin debian.vdi
