For the standard build of Xen, examining the binaries will not trivially
tell which version of Xen it is. There are functions in
.../xen/common/version.c, but those return one small part of the whole
version numbegr (eg 3.1.0 is major = 3, minor=1, extra="0") as integers
and strings respectively.

There is no "encoded" version numbers in some header or datablock that
you can search for, as far as I can see. 

Of course, "xm info" once the binary is booted would give you all the
info you need and more. 

I haven't looked at the "vmlinuz" if it's got any version info.
