Xen is not deprecated. The Xen support in EL5 is not going anywhere. The main issue as I understand it is that maintaining Xen is requiring more effort than expected because it has not been integrated into the linux kernel. Meanwhile KVM is already in the upstream kernel. It's not known yet what EL6 will have, but I think the indication from Fedora is that both Xen and KVM will remain supported: http://fedoraproject.org/wiki/Docs/Fedora8VirtQuickStart I could easily be wrong, though. KVM is certainly the wave of the future, but it's definitely not supported in EL5 (though there is the unsupported CentOS guide at http://wiki.centos.org/HowTos/KVM ) Also keep in mind that Red Hat recommends the libvirt tools (virt-manager etc) which abstract Xen or KVM commands. I'm guessing XenSource would want you to use the Xen-specific tools (xm etc). (By the way, you do realize that VMWare ESXi is free? It comes on servers from several vendors, including Dell and HP. It would be a pain to manage more than about 5-10 servers without the management console which is not free, though.) _______________________________________________ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
