Why don't you list Cloudmin in the list of management tools? The installation actually works the first time. All you do is download a script, chmod it, and execute. Then reboot and you have a web interface to your kvm, with tons of monitors and tools. You don't need special combinations of OS and KVM, you can set up your raid and lvm in linux before you install it. I repeat, it actually works without rocket surgery.
KVM installation with GlusterFS
I'm very interested about GlusterFS. I'm also interested about KVM.
I have a project : . Getting de distributed and "virtualized" storage with GlusterFS . Use this storage for a KVM installation, so that it can run as a VirtualSan installation
Can you tell me if you already done that ?
