I am about to find out about that myself one of these days as I am setting up a Xen system. However, according to the documentation and some forum posts that I've found via Google, it should not be quite such a problem. One only has to make sure that one exports the variable "IGNORE_XEN_PRESENCE=1" (or any other value than "0") prior to building the part of the driver that comes as source code and that interfaces with the kernel. In addition, the availability of virtualization extensions in hardware - in the form of an IOMMU - have greatly simplified things in that area. The only real scenario that I'm aware of in which case it would not work is if you try to run the nVidia driver in a Xen domU without that this domU has direct access to the video hardware. If it does have direct access to the video hardware - i.e. the video adapter is hidden from dom0 or "PCI-hot-unplugged" - then it's just as if you were running the nVidia driver in dom0, and that works rather well these days. -- *Aragorn* (registered GNU/Linux user #223157)

Sounds like a broken installation which is falling back on software rendering. (My X300 copes very nicely with reasonably complex 3D rendering using the open-source drivers.) > Went an bought a RV710 [Radeon HD 4350] Module: Card:ATI Radeon HD 2000 and > later (radeon/fglrx) teapot gave me 142 FPS on mandriva 2010.0. You need xf86-video-ati git, recent mesa (from git?) and kernel for that. Or you can use fglrx. [snip] -- | Darren Salt | linux at youmustbejoking | nr.

The one-click installation on [open]SuSE works perfectly for me, even on an XEN kernel. Other kernels may have more problems, of course. DoDi

However, whatever I get I will be testing with the latest and greatest open source drivers as well as the proprietary drivers - I'll only use the binary drivers if they really make a difference. |
