Our system requires either DVD or CD images in .iso format, or raw disk images – the equivalent of taking the stream of bytes off a physical disk and saving them in a file. A .vmdk file is a long way from raw format. However, qemu does have tools to convert these.
On a Linux system, you can use the following command to convert a .vmdk into a raw disk image that our system can use:
$ qemu-img convert inputfilename.vmdk -O raw outputfilename.raw
Be aware that a raw image is probably larger than the .vmdk, which is a compressed format.
Mac users can also perform this conversion using Oracle’s VirtualBox, by running the following commands in Terminal:
cd /Applications/VirtualBox.app/Contents/MacOS/ sudo ./VBoxManage clonehd drive.vmdk drive.raw –format RAW
