IMHO they are architecturally broken and should be redone from scratch.

In particular the "live update of the backing C struct" aspect is broken
in various respects IIRC and difficult to fix (the original author is
also long gone).

I expect this brokenness relates to why things appear to return 0 for
you.

IMHO a much more sensible approach would be to follow what the ocaml
bindings do and do on demand translation between Python<->C as you call
the libxl functions.

Not much Xen experience, mostly Python bindings experience (the
generator itself is in Python too as it happens).

I think it would be a fair effort though.

Ian.
