The biggest problem with live merge is libvirt not qemu.

Anyway the qemu-kvm/qemu-kvm-rhev problem is relevant only for centos and centos has a specific way to address these special needs: http://www.centos.org/variants/ """ A CentOS variant is a special edition of CentOS Linux that starts with the core distribution, then replaces or supplements a specific subset of packages. This may include replacing everything down to the kernel, networking, and other subsystems. """ I think the plan was to have our own centos variant (shipping qemu-kvm-rhev). I remember Doron participated to the centos meetings but I don't remember the outcome.
