I know I can do this. This is not the point of my post. I can do many
akward things, including having separate FreeBSD machine just for
building 2MB kernel with Xen enabled. But why not just provide prebuild
XEN-enabled kernel image on FTP server? Clearly it is possible, because
I just installed fully functional system using kfreebsd-9 kernel from
Debian [1].

After building freebsd release, recompile it again with Xen enabled, and
extract new kernel. Then just put such kernel on .iso in separate
directory or on ftp mirrors as separate image like as in netbsd or
debian, and no compilation by user will be needed. It is about 2-4MB, will
not harm even -bootonly.iso image.

By telling me to compile kernel by own you are just like telling potential user:

  "To install FreeBSD you need to have FreeBSD installed".

It is not the best answer (as clearly I was able to install FreeBSD on
Xen without having FreeBSD or any compilation!, just using Debian's
kernel, but would like to use or have possibility to use
upstream/original kernel).

Also not everybody have access to HVM instance (due lack of hardware
support). Compilation also takes time, and can be complex task,
especially considering there is no mention of Xen or Xen specific kernel
compilation in the FreeBSD handbook. It unacassarly makes 10 minut task,
a 20+ hours task.

For solving some minor problems, I can always just mount ufs under linux
or have separate 'administrative' domain, to which I can attach
additional disks to check what is wrong. No need to HVM instance. I can
also do many other things, including accessing block device using iSCSI,
which make it easy to use on another freebsd (virtualized or not) host.
Again no need to HVM even when doing serious disaster recovery.

So how about providing prebuild binary kernel image with Xen enabled,
just like netbsd is doing with own kernel, or like Debian is doing with
kfreebsd?

Who I need to contact from release / build team to make it happen in 9.1
or 10.0 ?

 [1] (only missing thing is that getty is trying to open /dev/vt* but,
 should actually open xen-specific tty/console, easly fixable by editing
 /etc/inittab, something which should be actually done by bsdinstaller
 after detecting it is running on Xen).
