No, the low-level interface between the kernel is an ABI, which will be as stable as your hypervisor author/vendor wants it to be (which is generally "very stable"). The question is whether that low-level interface is exposed to the rest of the kernel directly, or hidden behind a kernel-internal source-level API.
