Hi,
The attached patch adds a new option '-rawdiskimage' to the createrawvmdk
command. With this option, raw disk images can be used directly without
loopback devices. I think this is useful for users who wants to run the same
disk images on different virtual machine software. I tested on Ubuntu Linux,
but I hope this simple patch works on other environments too.
This patch is under the MIT license.
