[libvirt-users] convert physical windows 8 machine to virtual machine

I dual boot w8 and Arch Linux. Both are on the same ssd drive (each OS have of course a partition). Now I would like to virtualize w8 and run it inside Arch Linux using KVM/QEMU and Libvirt. w8 has already been installed on a ntfs partition. As it is brand new, it will not be difficult to reinstall it on a image.raw I have been reading some articles and found myself a little bit confused. 1- Some articles point to driver issues on the windows size, which could lead to an unusable OS. Is this a real issue ? Workaround found is to uninstall IDE/SATA driver in w8 and then install general/universal driver. 2- I can of course copy my w8 partition to a image.raw in my second HD, then create the VM. But in this case, after time, I will not have the same w8 on my ssd and my VM. What I am looking for is a VM that will ever replicate w8 on ssd. In this case, I guess I need to reinstall w8 on a raw qemu-img then use this image for the VM. Am I correct ? Is there anyother solution ? Is it worth keeping the raw image on the ssd for better performance,or moving the image to the other HD will make no difference? 3- Most of the reading talk about virtualise a physical windows using Virtualbox or VMware, which I certainly don't want. I would appreciate any good pointer for the overall set-up. Thank you in advance for hints, tips and advices.
