But what if the new version breaks some things, or changes behaviour in a way you don't want, or removes a feature. Your choice effectively becomes do I back port things I want to an old version, or maintain patches that takes current back to the state I want. > Which is better on C5 and C6 ? That's a matter for google, and not necessarily a simple one to answer. As was said, Xen was the standard option with C5, and KVM was with C6. jh
