[virt-tools-list] using a block device

[Mihamina Rakotomandimby]

Hi all, 

As suggested in this Ubuntu tutorial:
https://help.ubuntu.com/community/KVM/CreateGuests

Creating a windows guest is
  sudo virt-install --connect qemu:///system 
  -n xpsp2 -r 512 -f windows.qcow2 
  -s 12 -c windowsxpsp2.iso 
  --vnc --noautoconsole 
  --os-type windows --os-variant winxp

This is Ok, it creates a qcow file and all is fine.

Know, I setup a partition (/dev/sda10) just for the windows guest.
What would be the modified virt-install invocation in order to use 
/dev/sda10?

Thank you.
