[one-users] managing images

The valid values for target are : hda, sda, sdb, and so on.
1,2,3 are partitions on that disk. And yes, the disk in my case is a blank
disk created on the fly with fs disk type on which i have installed an OS
by booting the VM from a cdrom image and now I use it for my virtual
machines.
