I've used the following links to migrate our office servers:<br>

In any case, be cautious, make backups and don't do this at 3:00 AM.<br>

There isn't any pressure, at this point, to convert your VM
hosts to CentOS 6 unless there is some feature you require.<br>

While Xen will probably return in RHEL 7 simply because it is
part of the<br>
upstream kernel now I doubt it will be officially supported by
Red Hat.<br>
Between buying Qumranet (<a moz-do-not-send="true"
href="http://www.redhat.com/promo/qumranet/" target="_blank">http://www.redhat.com/promo/qumranet/</a>)
and now<br>
Gluster (<a moz-do-not-send="true"
href="https://www.redhat.com/promo/storage/" target="_blank">https://www.redhat.com/promo/storage/</a>)
it is clear that Red Hat<br>
aims to become a provider of a complete independent
virtualization stack<br>
and is unlikely to support "competing" products directly.<br>
<br>
The question is what does Xen offer that KVM cannot provide?
Looking at the<br>
slides of the KVM Forum 2011 (<a moz-do-not-send="true"
href="http://www.linux-kvm.org/page/KVM_Forum_2011"
target="_blank">http://www.linux-kvm.org/page/KVM_Forum_2011</a>)<br>
there seem to be many interesting improvements in the pipeline
so at some<br>
point the question really is why hold on to Xen at all when
there is not<br>
real reason to?<br>
