Both are the same - vmlinux-syms is just not stripped of symbol
information, and thus larger.
A while back, Xen stopped producing a separate Dom0/DomU kernel, and
just produce a combined "one-kernel-fits-all" file. This makes sense
if
you use modules, but if you use a "monolithic" kernel with all the
driver built-in, it makes the kernel a bit bigger, so may be a cause for
concern if you want to minimize the foot-print of the kernel.

That is built in the .../xen directory, which is a the same levels as
your linux-2.6.16.13-xen directory. It will end up in the
dist/install/boot directory together with the vmlinuz-<ver>-xen kernel
that you need to install into the /boot directory. ["make install"
will
do this for you if you install and build on the same
machine]>

As described above, it applies to both, because you use the same kernel.

Yes, the HVM support is builtin to Xen at all times. >
