Redhat have just released their latest Enterprise Linux offering Redhat EL 6. According to the CentOS twitter feed http://twitter.com/centos it will be 4-6 weeks before CentOS 6 is built and released publicly.

The two biggest changes for me are that exim is now no longer in the Redhat Repository and Xen DomU supported kernels have been dropped in favour of KVM technology.

Exim is the only MTA I really want to use, so I won't be switching to Postfix or sendmail. Thankfully, rebuilding the Latest Exim Source RPM from Redhat 5 on Redhat 6 seems very easy, so it shouldn't cause too much of an issue that I can see. Once CentOS 6 is released, I'll post an article about getting Exim running on 6, so keep posted.

I'm very intrigued to use KVM, I've had very little experience of it, but I've used Xen a lot, building our entire Linux VPS platform around it. The "bonusses" of KVM are looking interesting, especially the memory overcommit facility that's available. If I can get some hardware to test with I'll look at the ease of building up a redundant KVM cluster.
