Suggest you read > the archives of the list for all tips and caveats. I've been using the stock Xen (2.6.18) that comes with the latest CentOS 5.2 in production without major issue. At one time I had to restart xend occasionally to be able to properly reboot guest OSes from virt-manager, but even that has stabilized. What specifically is better about 3.2 that you are recommended it over 2.6.18? My experience to date with CentOS is it tends to run the latest, proven stable version of each package, which would make me hesitant to run downloaded packages. As far as virt-manager, use ssh -X or ssh -Y to connect to the DomU then start up virt-manager, this should reflect the GUI back to the originating workstation. Brett
