This is because of include/xen/interface/xen-compat.h:

#if defined(__XEN__) || defined(__XEN_TOOLS__)

/* Xen is built with matching headers and implements the latest interface. */
#define __XEN_INTERFACE_VERSION__ __XEN_LATEST_INTERFACE_VERSION__
#elif !defined(__XEN_INTERFACE_VERSION__)
/* Guests which do not specify a version get the legacy interface. */
#define __XEN_INTERFACE_VERSION__ 0x00000000
#endif

So, one needs to specify the version (QEMU does that via its configure script after

some tests)

You mean specifying via Kconfig something like "0x00040d00"?

And what about the headers? How will we provide their location if we decide not to include those

in the tree?
