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

</div>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 href="http://www.redhat.com/promo/qumranet/" target="_blank">http://www.redhat.com/promo/qumranet/</a>) and now<br>
Gluster (<a 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 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>
<br>
