FWIW we did start to make golang bindings for libxl (see
xen.git/toools/golang/xenlight). I think golang is an obvious language
to write Xen control stacks in.
The main issue I see at the moment is that while the *API* between a
toolstack and libxl is backwards-compatible, the *ABI* between the
resulting binary and Xen is not; meaning that every time you change your
Xen version, you need to recompile your golang programs. (This of
course is not limited to golang, but it was highlighted to me when I
started to use go-xenlight.)
But I'd definitely be interested in seeing what your community members
are doing, and if we can come up with a useful solution.
