I donât know a lot about this stuff, but couldnât you put the pciback module in your initrd instead of doing all that manual stuff?

I think is working? Hi Mark! Thanks for the reply and clarification! Just an update to all on the list, I decided to use the stock Xen linux kernel from CentOS and only recompiled Xen 3.2.1 itself in another thread which I started and updated here on Xen-users. The recompiled kernel based off of the CentOS source worked, but it was behaving a bit "odd" so I blew it all away and started over. Turns out I didn't need to recompile the CentOS kernel to add VT-d support. I would of liked to have pciback module compiled directly into the CentOS kernel, but I'm just unbinding things at boot and loading the pciback module manually upon startup... which works fine for me! Thanks, all!

Intel processor model 23 for P6 class family is not supported That's nothing to do with VT-d, Xenoprof is a profiling app (e.g. for conducting performance analyses, etc). Don't worry about it :-) Cheers, Mark I have an E8400 on an Intel DQ35JO motherboard and the references to iommu_page_fault but I think that's just info and nothing else? For reference, this is on CentOS 5.2 w/custom Xen kernel I built using CentOS xen kernel source (2.6.18-92.1.6.el5-xen-x86_64) with Xen 3.2.1 tarball. -- Daniel Kao Ãbermind, Inc.
