Becasue libvirt was designed by goats who'd been sniffing too many pheromones. Let's just say that they were not paying attention to Eric Raymond's guidelines on open source GUI's (http://www.catb.org/~esr/writings/cups-horror.html) and leave it at that. Our favorite upstream vendor is usually quite good at writing gui's, having learned a lot of lessons over the years and having strong developers. libvirt is not one of their shining efforts. VMWare, especially its LabManager suite with which I've worked recently, does a much more thorough job. It's not perfect: the update of VMwareTools with kernel updates is hardly perfect, and its interactions with the NetworkManager of SL 6 and RHEL 6 are not good. But I'm not thrilled with NetworkManager in servers or managed environments, either. I've heard good things about KVM performance, but didn't see it in RHEL/CentOS/SL 5.x. I'll be very intersted to see the results of the Debian testing I'm doing in the near future.
