Sure! kmview is not included in our Debian packages yet as it relies on
(still) non mainstream features (utrace), but the code is available on
our view-os svn repository.

Check out:
svn co https://view-os.svn.sourceforge.net/svnroot/view-os view-os

More specifically to browse the code/specifications:
The kmview device protocol is here:
http://wiki.virtualsquare.org/index.php/KMview_module_interface_specifications
The kernel module itself is here:
http://view-os.svn.sourceforge.net/viewvc/view-os/trunk/kmview-kernel-module/
The VMM userland application share most of the code with
umview, the source code for both is here:
http://view-os.svn.sourceforge.net/viewvc/view-os/trunk/xmview-os/xmview/

kmview kernel module (current version) needs the following patches:
utrace

http://www.mail-archive.com/utrace-devel@redhat.com/msg00655.html
I am trying to keep everything up to date, but the whole stuff is
evolving in a quite fast way.

Everything has been released under GPLv2.
