Hi All, I haven''t tried to pciback a device yet and setup an HVM but finally got to a point where I think I have VT-d working, but wanted to make sure this looks right from my "xm dmesg" output: (XEN) Intel VT-d has been enabled [snip] (XEN) xenoprof: Initialization failed.

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!

I don’t know a lot about this stuff, but couldn’t you put the pciback module in
your initrd instead of doing all that manual stuff?

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!

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 :-)

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.
