Aeolus is different from OpenStack.

. Aeolus is GUI for controlling and migrating workloads across heterogeneous clouds. eg. Start your loads running on AWS, migrate them to Rackspace or another OpenStack cloud.

. OpenStack is a (kind of) open source equivalent of AWS, so you can run a private or public cloud on your own equipment.

As for Red Hat's involvement. Well, code and contributions talk. Hot air from Microsoft and others, walks ...

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!

If anything, OpenStack is more of a competitor to oVirt, though there are significant differences between the two.

They touched on the interaction of the two at a recent workshop:

http://www.ovirt.org/wp-content/uploads/2011/09/Ovirt-WorkSh...

    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.

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].
