Xen is hardware agnostic.

I just built a new dual Xeon server system with IOMMU / Intel VT-d. Does Xen currently support these features?

LOL.

I recall that Viet Tam sent me a personal email may years ago in regards to running dual displays under Windows 2000. Definately an extremely intelligent software engineer.

I just thought it was funny that the term "cross-pollination" was used in your post.



Carry on please.

PS: I do have great respect for the Linux support personnel that NVIDIA provides in these forums. Unfortunately, "Linux" seems to be fragmented these days with all the various distributions that are available.

Some news.
Xen 4.0.0 is coming(rc2 atm)

"This does seem to work for basic cards, ie Intel and some ATI but not NVIDIA Cards as they still need the
pBAR=vBAR patches."

CentOS5 is based on RHEL5.

The kernel version number is somewhat irrelevant in RHEL as Red Hat backports updates to a stable kernel ABI over the life of the product. So no, it's not really old, it's totally current in Red Hat's world - there was an update last week, and next week will see the release of RHEL5.5 which brings even more backported features and driver updates.

I have no idea if that method works with the latest mainline kernel releases - you'd have to ask the Fedora crowd - I was just passing on the information

Did you figure out anything on this? I decided to try 2.6.32.12+xen patches because there was no chance of getting it to work on pvops.

Default Re: Nvidia support for Xen

running 2.6.31.12 + rebased suse patches

The gist of the issue: in nv-linux.h there is a call to a deprecated pgd_offset_k() function which is pulling in the init_mm symbol. I'm not a C coder though. If this call is only needed for older kernels I think an #ifdef thereabouts may provide a decent fix. I have no idea though. I just deleted the call, recompiled and the module inserted fine. I've been running Xorg for a little while, glxgears works, no real testing though.

$ glxinfo | grep -i rend
