Without going OpenStack, does anyone know if there's ever going to be a snapshotting feature in KVM on SL like VMWare and VirtualBox have had forever? That's the biggest thing missing for me, I can't use the normal virtual environment easily for testing builds or application packaging, I have to run a VirtualBox on my laptop, which is a bit of a pain...

It's not the KVM itself. It's libvirt and virt-manager the built-in management tools in Scientific Linux. Virt-manager has gotten noticeably better, but it's really not up to enterprise support.
*Openstack* might be, I've not had the chance to use it myself yet.
The Virtualbox free tool has its own issues, mostly the lack of commercial support for it. So definitely, on SL 6 servers and for SL 6 virtualized clients, the free VirtualBox is *really good* for lightweight use.

For enterprise scale use, of over, say, 5 nodes and with ability to migrate VM's from one server to another.... I've not tried their commercial offering. I'd have to try it. I hope it would be as good as the free server.
