The current release candidate of Eucalyptus, version 1.6.2-rc1 and the current release candidate of Euca2ools, version 1.2-rc1, can be installed from source or as binary distribution-specific packages (CentOS, Debian, and openSUSE).
WARNING: The RCs are intended for beta testers who are willing to try out recently developed software, which is still in the process of being field tested and documented.
