Dear Weidong,
 
I am using Xen 3.4.1 testing with pv-ops dom 0 kernels 2.6.30-rc3 or
2.6.31-rc6.
 
May I know where I can download changeset 19893 source code and patch Xen 3.
4.1 testing with this changeset?
 
Thank you.

Xen 3.4.1 doesn't include the changeset 19893, so it cannot work for you.
Basically, I use 2.6.18 dom0 with Xen 3.4, and use pv-ops dom 0 with
xen-unstable. Anyway, you can port the c/s 19893 to your code, and try
again.
 
Regards,
Weidong

Hi Weidong,
 
I can confirm that I am using Xen 3.4.1 with changeset of 6 August 2009.
However, I can't remember the changeset number. I need to get home after
work to find out.

Hi Weidong,
 
I believe I am using Xen 3.4.1 with changeset of 6 August 2009. I can't
remember the changeset number. I will check and get back to you later.
 
Thank you.

What version of Xen are you using? Make sure after c/s 19893, which enables
pci-stub to hide devices for assignment.
 
It works fine for me.
 
 > When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says
permission denied
It doesn't matter. It is the same to pciback. You will get the same message
when you do "cat /sys/bus/pci/drivers/pciback/new_id".
 
After use commands to hide 01:00.0 with pci-stub, can you see it use command
'ls /sys/bus/pci/drivers/pci-stub/'?
 
 
Regards,
Weidong

Problem


I find that following the instructions here at Xen Wiki VtdHowTo don't work:



Binding Devices to pci-stub

If using pv-ops dom0, also can use pci-stub to hide devices for assignment
(example PCI device 01:00.0) * lspci -n * locate the entry for device 01:00.
0 and note down the vendor & device ID 8086:10b9 . 

...

01:00.0 0200: 8086:10b9 (rev 06)

...


* then use following commands to hide it: . 

echo "8086 10b9" > /sys/bus/pci/drivers/pci-stub/new_id

echo "0000:01:00.0" > /sys/bus/pci/devices/0000:01:00.0/driver/unbind

echo "0000:01:00.0" > /sys/bus/pci/drivers/pci-stub/bind



When I tried to "cat /sys/bus/pci/drivers/pci-stub/new_id", it says
permission denied.



My NVIDIA graphics card is using BDF 01:00.0. When I change directory to 

/sys/bus/pci/devices/0000:01:00.0/, sub-directory driver is not found at
all.



Then when I put in pci = [ '01:00.0' ] for the Windows XP Home HVM config,
it complains about pciback but I am using paravirt-ops dom 0 kernel.



And when I tried the "xm pci-list-assignable-devices", nothing shows up.



I have already specified iommu=1 in grub.



Hope the Intel folks can assist in this matter.
