Simple enough to give this a try, or, not really :). I recently worked on consolidating a bunch of storage which included a new NFS server for access to my distros for network installs. Having to finish this leads me to a dozen other things which need to get done, which leads to a number of... it just goes on. I'll get back to this as soon as I get a handle on the work I had started earlier. While searching on why I can't seem to get ServeRAID 4Mx controllers working all of a sudden, I came across an article on IBM's site that VMWare runs on the even older x440. Does that mean that Xen is the culprit, not being very compatible with older gear or something else?
