Xen users - Sep 2012 - Success VGA passthrough on windows 7 x64 with Xen 4.2.1-pre

I''m glad i can report that today i have 100% success with VGA
passthrough on windows 7 64-bit. That nasty yellow triangle with error
43 disappeared and my GTX560 has 7.8 points in aero index, also Gpu-z
and Cpu-z see vga card properly and unigine heaven benchmark have no
problem with it.
Now i have to figure which particular option let me to do this. Most
likely it was turned off msi_translate in DomU config, but i will make
more test and i will share with full information today later. Cause
i''m newbie with Xen and linux if there is some particular information
i can share with, then please tell me and i will try to do that.

One day before I have tried to do this without luck.

My configuration:
MB: GA-Z77X-D3H with latest bios (F15)
CPU: core i5-2400
two GPU GTX560 on 16x and 8x pcie ports (both works on 8x when two used).

DomU: win7 x64 pro

I have tried to do this with XCP 1.5b and XenServer 6.0 Free trial.

There is dmesg for host:
[root@xenserver-render ~]# xe host-dmesg | grep -i virtualisation
(XEN) I/O virtualisation enabled
(XEN)  - APIC MMIO access virtualisation

I just have "nasty yellow triangle with error 43" :)

So I''m interested in your experience and solution.

Mikhail.

Dear Dariusz Krempa,

I am also interested in knowing how you get the "nasty yellow triangle 
with error 43" to disappear.

In addition, may I know which guide did you follow in getting VGA 
passthrough to work 100%?

Thank you very much.

I started with guide from You dated 25 march 2012 to build Dom0 and
Xen 4.2, but with few modifications this time.
1) I used kernel 3.6-rc7 for Dom0 -->
http://kernel.org/pub/linux/kernel/v3.x/testing/linux-3.6-rc7.tar.bz2
2) I used Xen from http://xenbits.xen.org/hg/staging/xen-unstable.hg/
3) VGA patch from David''s Gis rev 25240
4) I used pciback to hide my gtx560 from Dom0, and for a while i have
had second gfx - hd4850, but now i removed it and i have only gtx560,
still working

and finally I think I know what make that error 43 disappeared. At
first I did comment those lines in DomU config:

#pci_msitranslate = 1
#pci_power_mgmt = 1
#xen_platform_pci=1
#xen_extended_power_mgmt=1

When i had success with installation i start to remove comments and
the one which is nasty is pci_msitranslate. This make some other
problems, like not working USB ports, but ...

If any other information will be needed please let me know.

Hardware:
asus P8H67
asus GTX560 DCII top
4GB ram

System:
ubuntu 12.04
Dom0 kernel 3.6-rc7
DomU windows 7 x64
nvidia drivers 275.33 - but possibly 275.50 also will work

Dear Dariusz Krempa,

Thank you for your prompt reply.

I don''t have pci_msitranslate = 1 in my Windows HVM domU config file,
so
I don''t think "pci_msitranslate = 1" is the main cause of my
"nasty
yellow triangle with error 43".

I checked DomU with and without msi and with msi i saw bluescreen and
turning it off, and DomU again start normally. Like I wrote, I also
have different kernel for Dom0, with 3.3-rc7 i had error 43 and today
first time installed xen 4.2.1-pre( from source). Yesterday and days
before that i had xen 4.2-rc2 -- 4.2-rc4. Im not 100% sure what
(kernel or new xen) fixed problem and for now i will play with windows
7, maybe tommorow or day or two later i will again reinstall Dom0 to
check which one solved problem. In mean time at least we know that its
possible to pass vga to windows 7 DomU, and how. Im sure that You and
maybe other users will try on her own system with settings I
described. There was also few more things i did just before i had
success, but i think it has nothing to do with it. Just mention it:
- removed opencl libraries under windows system,
- removed cuda libraries under windows,
- reinstall nvidia drivers to version 275.33 (there was 306.xx or
something, dont remember)

I once recorded that the default for the pci_msitranslate option was
"1". Not having this in your configuration then is like having it set.
Feel free to correct me if I am wrong. I have only gotten VGA pass-through to
work with a Windows domU, never in GNU/Linux for some reason.

Hi,

May I know whether your GTX 560 is a Ti or a non Ti, that is, GTX 560 or 
GTX 560 Ti?

just 560, without Ti

I know I shouldn''t reply to myself, but I have hvm DomU with windows
server 2008 r2, and i only turn on gfx_passthrough and
pci=[''1:00.0''],
created guest and installed nvidia drivers 275.50 and full success.
Just like with windows 7.
I''m only having problems with windows 8 cause first available drivers
are 29x.xx and they don''t work. I have partial success with windows 8
and drivers 275.33 for vista/win7, cause system see my VGA but gpu-z
shows that only DirectComputing is enabled, no CUDA, no PhysX, no
OpenCL.

Thanks for this information, it was much appreciated! I will be updating my

Dear Dariusz Krempa,

Could you publish your xen vga passthrough configuration files, namely 
the windows 7 x64 HVM domU configuration file?

I have tried setting pci_msitranslate to 1 and also 0 but the nasty 
yellow triangle with an exclamation mark and error 43 won''t go away. 
pci_msitranslate has no effect on my system.

Thank you very much.

Hi,

I have applied Xen VGA passthrough patches from David Techer''s personal
website to Xen 4.2.1-pre source tree. Everything compiled and installed 
smoothly. But when I tried to start Windows 8 HVM domU with VGA 
passthrough, it gave me the following error:

xc: error: unable to allocate memory to the HVM guest. (16: device or 
resource busy): Internal error.

There are no issues with Xen 4.2-unstable changeset 25099 however.

Hi.
I did some researches to find out how I did install drivers for nvidia vga
under windows 7 DomU and this is my conclusion. No matter how system is
prepared, Dom0 and hardware, if it works with windows xp then could work
with windows 7 (my testing platform had Dom0 kernel 3.6-rc7 with xen
4.2.1-pre). Most important thing is how to foul windows to accept drivers.
This is how I did this. Three separate installations of windows 7 and each
time success:

1) for windows 7 installation in DomU configuration setup like this:
gfx_passthrough=0
#pci = [''1:00.0'']  // in my case NVIDIA VGA BDF is 1:00.0
#pci_msitranslate 
2) when You install windows 7 shut it down and change DomU config. show vga
to windows but don''t pass it thru yet:
gfx_passthrough=0
pci = [''1:00.0'']
#pci_msitranslate 
3) start DomU and install nvidia drivers. in my case 275.33 or 275.50, both
work and I didnt check newer

4) shut down DomU and setup his configuration. its finally configuration in
my case :
gfx_passthrough=1
pci = [''1:00.0'']
#pci_msitranslate 
5*)create DomU and drivers could works and no error 43


* because my system setup i need to restart Dom0  before step 5
** if there still will be reported problem with drivers under windows 7 I
will make more researches for different kernels/Dom0 configurations

Dear Dariusz Krempa,

I am unable to get vga passthrough to work with Xen 4.2.0 and Xen 
4.2.1-pre. After my Windows 8 HVM domU starts, it shows me a blank 
screen permanently. I cannot even get partial success with VGA 
passthrough with Xen 4.2.0 and 4.2.1-pre.
