For this I wonder if a better solution is actually to make the libxl
driver fill in the memballoon device. IIUC, you can't actually turn
it off, so all libxl guests will have this regardless.  So we should
just need to add the element a post-parse callback, and check for
unsupported "model" value when starting the guest
