Hi guys, At this page: http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU?highlight=%28xen%29 it says: "You will need an domU installation initrd image and kernel. Both can be downloaded from: http://mirror.centos.org/centos/5/os/i386/images/xen/" I'd like to suggest adding the following: "or http://mirror.centos.org/centos/5/os/x86_64/images/xen/" Thanks, Bart
