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

            bring XEN back<br>

            <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 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>
