Hi Jaime,

We spoke on IRC when I was trying to setup OpenNebula. Thanks for all the help and hints there!

It is right that I found that my primary problem was that I choose CentOS 6.4 from the list of supported distributions, as that is the one I'm most comfortable with.

If I had chosen Ubuntu from the get go, I would have have run into far fewer problems.

However, I don't think OpenNebula currently fulfills the goals I set up. If it indeed does, it would be really nice - and I would start over setting up OpenNebula on Ubuntu instead.

My problems with OpenNebula as far as goals go are:

Reg. goal a) From my initial experience, it seems I cannot rely solely on Ceph storage. Images have to be copied back and forth between the servers.

Reg. goal b) The qemu-kvm binary in the supported Ubuntu 12.10 distribution does not include async flush. I don't know if this is available as a backport from somewhere else, as my attempts to simply upgrade qemu didn't go well.
