Sounds good to me. How about:

hda             = VBD hda
vbd://hda       = VBD hda
ioemu://hda     = IDE hda

The VBD patches are not ready yet - so I'd like to propose that we do:

-            self.create_configured_devices()
+           if self.image.ostype != 'vmx':
+                self.create_configured_devices()

and

-        self.create_blkif()
+       if self.image.ostype != 'vmx':
+            self.create_blkif()

When our VBD patches are ready, we'll revert this.
