Perhaps I haven't been clear. This is not Windows specfic, I want to
do this for both Linux and Windows.

Lets say I have a disk image in QCOW format that I use with my Xen VM.
I want to retain the _same_ filesystem under VMware. So I first create
a VM in ESX with the same disk size. Then I use qemu-img to convert
the qcow image to VMDK format and overwrite the blank VMDK file
created by ESX. No go. I try the same thing but with conversion to RAW
format, and that fails as well. But this was expected.

So basically I want some way to take a qcow image and convert it for
use with ESX.
