To make it clear, this is EPEL-5. There was some still unresolved problem with adding a dependency on KVM: https://fedorahosted.org/rel-eng/ticket/2982 As a result, we have to depend on qemu (software emulation) instead. However you can easily change this at runtime by setting the LIBGUESTFS_QEMU environment variable: http://libguestfs.org/guestfs.3.html#libguestfs_qemu http://libguestfs.org/guestfs.3.html#qemu_wrappers In RHEL 6 it's all going to be different again. The same qemu-system-x86 RPM is actually KVM. We combine qemu and KVM sources during the build to make a 'qemu-kvm' binary which can do both software emulation (TCG) and hardware virt (KVM).
