I'm working on the capability of offering virtual servers using CentOS Linux and Xen. If anyone has experience with this and can give some pointers it would be appreciated. I've got the software loaded, the box booting the Xen modified kernel, Dom0 running, but the control panel has the New button gray'd out even if I'm root. I suspect it's because I don't have a profile built yet but I'm still grinding through the docs. Any advice from someone who has set this up would be appreciated, resource references, etc. Thanks.
