This is certainly one way to do it.  Bundling a whole qemu binary is
arguably as bad as breaking dependencies isn't it?

I also had a go at backporting the changes to qemu that we ship in
F-10.  qemu in F-10 is based on qemu 0.9, and doesn't include the
vmchannel patch.  The vmchannel patch looks deceptively simple:

http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg01042.html

However when I started to backport it, I discovered that the patch
depends on many extra functions and features added to slirp since
qemu 0.9.  I ended up with a qemu which compiled, but kept
segfaulting, and it was tricky to diagnose exactly why.

Is it really a problem to use the libguestfs and/or qemu packages from
Fedora 11 builds?  You can grab the latest builds out of Koji:

http://koji.fedoraproject.org/koji/search?match=glob&type=package&terms=libguestfs
http://koji.fedoraproject.org/koji/search?match=glob&type=package&terms=qemu

This worked OK for me, although I have now moved to using Fedora
11-Preview, and have mostly abandoned Fedora 10.
