The simplest fix is just to change qemu by setting LIBGUESTFS_QEMU=/usr/bin/qemu-kvm (see: http://libguestfs.org/guestfs.3.html#qemu_wrappers) In broader terms, I think this is an issue with how libguestfs is built: http://cvs.fedoraproject.org/viewvc/EL-5/libguestfs/libguestfs.spec?view=... http://kojipkgs.fedoraproject.org/packages/libguestfs/1.0.85/1.el5.9/data... checking for qemu-kvm... no checking for qemu-system-x86_64... /usr/bin/qemu-system-x86_64 checking for guestfwd support in /usr/bin/qemu-system-x86_64... no Apparently we need to BuildRequire kvm (not qemu-system-x86) on EL-5. I'll have a look at fixing this.
