libvirt users - Jun 2013 - 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

Surely there must be someone here that knows how to do this?  Maybe
someone that has used some other partition type in this way?

If I'm not mistaken, the fact that it is only a partition (and not whole
disk), you cannot passthrough it to the guest as a lun, but that
shouldn't be a problem for you.

You should be able to safely select the last option and
virt-{install,manager} will detect that it is a block device and use
<disk type='block' device='disk'> for the disk.
