The Qemu based tools in libvirt, and their implementation in virt-manager, should be taken out back and forced to read Eric Raymond's screed on open source interfaces (The Luxury of Ignorance). Compatibility with arbitrary virtualization suites is not your friend when it's done that badly. Simple operations, like "set up two disks at first setup", are not possible from the GUI. This is one among numerous utilities available from the command line setup tool that are not accessible from the GUI: that's just a failure of GUI design. KVM, itself, was unusable in my testing due to the "bridged network" mishandling and its complete lack of a concept of failover for network issues, particularly pair bonding for the server itself. PXE for the clients was unusable, and it ran like a dyslexic on too many opiates, slow, twitchy, and unpredicatable. VMWare works well, even the free personal versions, and Xen used to work well (although its purchase by Citrix has me concerned, I've not played with it in 2 years now, and I'm very unhappy with libvirt.)
