Look in LibvirtVMDef.java (I think) for the disk definitions. There are
ones that work for block devices rather than files. You can piggy back off
of the existing disk definitions and attach it to the vm as a block device.
The definition is an XML string per libvirt XML format. You may want to use
an alternate path to the disk rather than just /dev/sdx like I mentioned,
there are by-id paths to the block devices, as well as other ones that will
be consistent and easier for management, not sure how familiar you are with
device naming on Linux.
