OpenStack isn't an open source AWS, it's also vm management. It works with XenServer, KVM and ESX. I can't speak for Aeolus, but OS had 3 components last I checked (Nova - the app server, Swift - storage, and Glance - image catalog). I think they were working on an auth module (Keystone?) and network virtualization (Quantum).
I don't think they support migrating between heterogeneous cloud types (which is a complicated beast), though. Does Aeolus really do that?
Love what you said about code + contributions vs. lip services!
I didn't mean to imply that OpenStack was "open source AWS", just that it's analogous. Of course OpenStack does more, is more interesting (because it's open source), and is only going to get better.
Migration is an interesting point: The aim is definitely to do non-live migration, possibly using Snap[1]. At the moment you can recreate configurations on different clouds[2].
The oVirt project is focused specifically on Data Center
virtualization management, related technologies and
tooling. oVirt brings the richness required by Data Centers
to an open-source platform. OpenStack is focused on
cloud which requires a minimum around virtualization
richness and rather focuses on cloud features.
In addition oVirt will be an open virtualization management
ecosystem, and may use components from OpenStack or
any other community project in achieving that goal.
OpenStack and oVirt can be seen complementary in the
same way OpenStack has VMWare driver support.
