Normally, "drbd:" disk strings would be handled by
/etc/xen/scripts/block-drbd, I think ?  Why does remus need to do
something different ?

The block device handling in libxl is in a bit of a state of flux but
perhaps it would be useful to start thinking about whether remus could
use it ?

Thanks,
Ian.
