Yes, upstream qemu is going to need this too.
So far we haven't needed any xenstore command in upstream qemu, because
we have been using qemu's own rpc mechanism, called qmp.
There is qmp support in libxl already, so it shouldn't be difficult to
use it, instead of sending the command through xenstore.
