There are a few.  However I'm quite happy to accept patches to make it
work / work better on FreeBSD.

Unfortunately debootstrap is not going to help.

The package that libguestfs depends on is 'supermin':

  http://libguestfs.org/supermin.1.html

Supermin makes certain assumptions about package managers that may or
may not apply to FreeBSD ports/packages.  For example:

 - that a package manager (similar to rpm/dpkg/etc) exists

 - that it packages pre-compiled binaries (not sources)

 - that you can list out the files belonging to a package

 - that there are dependency relationships between packages

 - that all files on the filesystem are part of a package (except
   user-generated files)

There are various ways to make libguestfs work without supermin, see
the FAQ here:

  http://libguestfs.org/guestfs-faq.1.html#how-can-i-compile-and-install-libguestfs-without-supermin

although depending on a Fedora-built appliance may not be very
satisfying.

You could build a fixed FreeBSD-based appliance, but distributing it
wouldn't be very nice, and getting security updates even less so.
Supermin solves these kinds of problems.
