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/msg00654.html 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. renzo
