I agree with removing the Linux-ism's, as it will only make it more
portable. Do you have an example of header files that I should be looking
for?

Here are two obvious candidates:

$ grep linux/ src/qemu/qemu*.c
src/qemu/qemu_driver.c:# include <linux/kvm.h>
src/qemu/qemu_driver.c:/* add definitions missing in older linux/kvm.h */
src/qemu/qemu_process.c:#include <linux/capability.h>

I just saw this, so please disregard any subsequent requests to find headers
:)

Here is the source for libkvm in FreeBSD:
http://svnweb.freebsd.org/base/head/lib/libkvm/

Here are some ports for FreeBSD:
http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/kqemu-kmod/
http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/kqemu-kmod-devel/

http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/qemu/
http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/qemu-devel/

There are ports for qemu for FreeBSD, that compile modules (above), and I
have used them and they work great. What information to use from those is
probably going to be a good key to figuring out what needs to get it working
for libvirt.
