Following up: I've gotten full virtualization of CentOS 6 on an SL 5 Xen server by using the "virt-install" command and avoiding manual editing of /etc/xen/ config files. I've also been reminded, forcibly, of why I hated the "/etc/xen" directory. The lack of distinction between a "/etc/xen/myserfer", the example files there, and any other unqualified files there as valid configation files means making safe backups of the files such as "myserver.hvm" or "myserver.old" quite painful. I wound up putting /etc/xen/ under git source control, just for tracking changes.
