[libvirt-users] Using a Windows partition as libvirt media

I'm running Ubuntu desktop 12.10 with libvirt and virt-manager (gui). I have been led to believe that it is possible to use and existing partition as the disk storage volume for a virtual machine. The windows partition is /dev/sda2, but if I use fs: Pre-formatted Block Device I can select the partion. What I can't figure out is how to tell the vitual machine to use this volume. I tried with virt-manager, but the only options I have are * Local media * Network install * Network Boot * Import Existing Disk Image How can I do this? regards Roland Giesler
