[Xen-users] VTD not working on Intel DX58SO w/ Xen 4.0.1

Hello,

I''m having problems with VTD on this board. The board/cpu/bios all
support vt-d and I think maybe I''m just missing something?
Any feedback would be much appreciated :)

Output below:

Please follow the steps outlined in
http://wiki.xensource.com/xenwiki/XenParavirtOps
in the sections with the word "troubleshoot". We need the full Xen
serial output.

Also look in http://wiki.xensource.com/xenwiki/XenCommonProblems.

Interesting that you should mention this today.  Just last night 
I was getting ready to order the dx58so as recommended on the 
VTdHwoTo wiki page (http://wiki.xen.org/xenwiki/VTdHowTo).  But when I 
went to 
the Intel "compare products" site, it says the dx58so does *not*
support
VT-d
(http://ark.intel.com/Compare.aspx?ids=36888,42486,)

I was just going to post to see if anyone knew for sure that it did work, 
or if the wiki was wrong.

Re: [Xen-devel] VTD not working on Intel DX58SO w/ Xen 4.0.1

just fyi it definitely supports vt-d i have it working on another
machine with a older version of xen (3.3) and a i7 950. I remember at
that time 3.4 was the latest and i had much worse problems trying at
3.4. i am now building a new machine and wanted to give 4.x a whirl to
see if the issues had been fixed :)

i am building more a current dom0 kernel as we speak so i will post
more details fairly soon along with serial output

What should one look for in their output to determine if VT-d is working and
detect.

My system board also claims to not support the technology, but I thought it was
working in my 4.0.1 setup.

Thanks.

Please add "iommu=verbose" option for xen.gz in grub.cfg,
then reboot and then paste full Xen hypervisor "xm dmesg" output.

[Xen-devel] Re: [Xen-users] VTD not working on Intel DX58SO w/ Xen 4.0.1

ok here is the logs with 2.6.32.26 using pasi''s config for 2.6.32.25
and iommu=verbose at boot. unfortunately this board doesnt have serial
and i dont have a spare serial card handy, so hopefully this will help
us figure it out :)

Virtualization Technology for Directed I/O (VT-d) extends Intel''s
Virtualization Technology (VT) roadmap by providing hardware assists
for virtualization solution. VT-d continues from the existing support
for IA-32 (VT-x) and Itanium® processor (VT-i) virtualization adding
new support for I/O-device virtualization. Intel VT-d can help end

performance of I/O devices in virtualized environment. These inherently
helps IT managers reduce the overall total cost of ownership by
reducing potential down time and increasing productive throughput by
better utilization of the data center resources.

With this, you could give -unstable c/s 22348
(http://xenbits.xensource.com/xen-unstable.hg?rev/2dfba250c50b)
a try (backported already as c/s 21379,

Re: [Xen-devel] Re: [Xen-users] VTD not working on Intel DX58SO w/ Xen 4.0.1

I''m willing/wanting to test if this fixes it, but how do I pull the
sources? Is this is a fix for the hypervisor or dom0?

Re: [Xen-devel] Re: [Xen-users] VTD not working on Intel DX58SO w/ Xen 4.0.1

hey Jan,

I was finally able to test that changeset, and I''ve made it a little
further. Now upon starting the domain I get:

# xm create vm-nine.cfg
Using config file "./vm-nine.cfg".
Error: Timed out waiting for device model action

Some background:

# xm pci-list-assignable-devices
0000:02:00.0
0000:02:00.1
0000:02:00.2

# xm dmesg
(XEN) [VT-D]iommu.c:1785: VT-d page table not sharing with EPT table
(XEN) [VT-D]iommu.c:1500: d0:PCI: unmap bdf = 2:0.0
(XEN) [VT-D]iommu.c:1373: d4:PCI: map bdf = 2:0.0

What can I do to help troubleshoot further?
