I've been wrestling with Xen for a week or so now but before I post some articles about Xen itself I'd like to share this quick hack to get the Nvidia binary driver working with the SUSE 10.1 Xen kernel.
While the 'nv' driver is excellent it's nice to have all the features of my hardware available, even if unfortunately it means using a blob driver from Nvidia. Also the nv driver doesn't seem to probe my monitor using EDID and seems to use more generic modes. This means that while overall image quality is excellent, the DPI is wrong for my hardware and so I have to tweak font sizes and such things. It may be possible to fix this by using custom modelines in my xorg.conf, or to force the nv to probe my screen using EDID but for that amount of effort I may as well get the Nvidia driver working.
Anyway, here's the hack to get the latest Nvidia driver ( 8762 as I write this ) working with the Xen kernel. It should work for x86_64 also but I only tested it for x86. Props to JaXXon on the nvnews.net forums for the original FC patch.
