EPEL ("Extra Packages for Enterprise Linux") is an additional repository you can use to add packages to RHEL and derivatives. Modern libguestfs (1.19.xx) is now available in EPEL 5 updates-testing: http://koji.fedoraproject.org/koji/buildinfo?buildID=327975 https://admin.fedoraproject.org/updates/libguestfs-1.19.13-4.el5 It is VERY important that you read the release notes BEFORE trying this package: http://pkgs.fedoraproject.org/gitweb/?p=libguestfs.git;a=blob;f=README.EPEL-... You can follow or join in upstream development of this package in the "oldlinux" branch in git: https://github.com/libguestfs/libguestfs/commits/oldlinux I suspect this branch may be applicable to other distros (eg. Debian 5 w/o backports) that don't supply new enough qemu or kernel to run the main branch of libguestfs.
