I confess I don't follow this patch in its entirety but it seems safe
enough in the sense that it's not going to affect users who aren't
using vscsi.

We are winding down xend maintenance in favour of the new libxl
library and xl command line tool.   xl is supposed to be commandline
compatible with xm.  So you should probably check that libxl does the
right thing with your setups.

I'll apply your patch.

Thanks,
Ian.
