hi,

being dissapointed a bit by ATI's support for Xen, I just purchased a top-of-the-line Dell box with an expensive NVidia graphics card, as rumour said they would work better than the ATI ones. Unfortunately, the NVidia installer detects that I am running Xen, and then refused to compile the kernel module, saying that Xen is not supported. Does anyone know of a way around this check, or have fresh experiences getting Xen and NVidia to play together?

Now, there may be calls to say that I'm biased here, but I'm really not working with the ATI-side of AMD anyways, so:

The reason it refuses to compile the kernel module is probably more to do with the fact that the guys at nVidia KNOWS that it's not going to work anyways. If that's the case, it's not really much point in bypassing the check itself.

It works just fine on Xen kernels from what I can tell. There are 3rd party YUM repos which provide pre-compiled nvidia modules which work with the Fedora Xen kernels.

$ uname -r 2.6.19-1.2895.fc6xen $ cat /proc/modules | grep nvidia nvidia 7760984 32 - Live 0xffffffff8826b000 (P)

Now perhaps the RPM has been patched to make it compile on Xen, or perhaps it is just a bug in the installer script, but it does look like it works. In either case one should file support requests with NVidia directly since it is a closed source driver which means open source developers can't do much (if anything) to debug problems without risking getting tainted by/violating the licensing terms.

Dan.
