I've read a couple of articles that Eucalyptus doesn't support bootable EBS yet. This is a problem since you can't make a backup form an instance like you a able on Amazon cloud or Rack Space Cloud.

If you ever reboot the physical Ecalyptus sever that's running the node controller the instance is gone along with all your settings. Are there any alternatives to Eucalyptus or is just the only game in town when it comes to open source cloud?

Here are 3 open source cloud projects:

If you are looking for free vs open source and have a small cluster. Nimbula Director is a commerical offering which is free for up to 40 cores.

as mentioned by kim0, Eucalyptus 3 will have boot from EBS. Another solution which you can already employ with 2.0 is mentioned here http://open.eucalyptus.com/wiki/install-service-ebs-volume. For example support.eucalyptus.com runs this way http://open.eucalyptus.com/learn/first-service-in-the-cloud.

Bootable EBS is coming in Eucalyptus v3.0 which should launch in a few months. OpenStack is shipping with Ubuntu 11.04 and should be a respectable alternative

From what you know does OpenStack support backup images from instances the same way you can on RackSpaceCloud? –  itgorilla May 19 '11 at 19:40
    
sorry, could you explain some more? –  kim0 May 31 '11 at 15:53
    
On RackSpace for example you bring up an instance from an image. You can install, uninstall do all kind of settings on that instance. The nice thing about it is that on RackSpace you can make an image out of that running instance and back it up on CouldFiles service. That's the kind of functionality I was looking for my private cloud. –  itgorilla May 31 '11 at 17:01
    
But does Openstack have bootable EBS? Or is it best to wait for Eucalytpus 3.0 –  Jeremy Hajek Jun 5 '11 at 23:36

You should checkout CloudStack - it's the IaaS platform used by Zynga, Godaddy, Edmunds.com and about 60 more large clouds. And it's GPLv3.
