Xen VGA Passthrough Questions

Dear David Techer,

I have read through your article on Xen VGA passthrough on 
http://www.davidgis.fr.

It appears that the following command on your blog doesn''t work.

dmesg | grep 01:00.0 | grep BAR

The above command shows nothing at all. Is there an alternative solution?

Thank you very much.

Yours sincerely,

Teo En Ming (Zhang Enming)

Re : Xen VGA Passthrough Questions

Hi Teo,

The 3 first lines with pattern ''pci.*mem'' need to be returned


U need to use somethign like 


root@gemini:~# lspci |grep VGA
02:00.0 VGA compatible controller: nVidia Corporation Device 0ca2 (rev a2)
root@gemini:~# dmesg|grep 02:00.0 |grep '' pci [0-9].*mem''|head
-n3
[    0.174458] pci 0000:02:00.0: reg 10: [mem 0xfb000000-0xfbffffff]

Re : Re : Xen VGA Passthrough Questions

You''re welcome.

Keep in mind that if you are going to upgrade BIOS for your motherboard, those
values for your card may changed.

I was in this situation last time  BIOS was upgraded.

It does mean that those values will changed each time you upgrade your
motherboad BIOS but having thos values changed after a BIOS upgrade could occur
for a specific upgrade.

Don''t ask me why...I do not know.

So you will be well advised to heck those values for each BIOS upgrade.

Moreover don''t waste your time to test VGA PassThrough for NVIDIA for
Windows  7. For Windows 7 use ATI.


I did my tests for playing with wine 1.4/1.5 on domU Ubuntu Lucid 10.04.4 PV HVM
(game like Crysis 2) and it rocks :)


My configuration:

Manufacturer: MSI / Product Name: H61MU-E35 (MS-7680) 

Bios version: V10.11

Dear David Techer,

Thank you.

I think the following command is sufficient.

dmesg | grep 01:00.0 | grep "pci.*mem"

Yours sincerely,

Re: Re : Re : Xen VGA Passthrough Questions

Hello,

Supposedly both the board & CPU must have VT-d, the E6300 does not:
http://ark.intel.com/products/41493/Intel-Pentium-Processor-E6300-(2M-Cache-2_80-GHz-1066-MHz-FSB)

If pciback was compiled into your kernel (not a module) then you can add
"xen-pciback.hide=(01:00.0)" to the module line in your grub.cfg,
substituting your lspci device names.

nVidia supposedly requires patches and only works in Windows XP, there are
a few Windows 7 success stories, but they seem rare.  Most people have
success without patches using AMD cards.

Best of luck.

How to Stop lightdm Display Manager and X.org X Server in UBUNTU 11.10 and Unload nouveau Kernel Module? (Xen VGA Passthrough)

Re : Re : Re : Xen VGA Passthrough Questions

You need to add nouveau.blacklist=1 in the grub.cfg of your domU

Have access to partition table of your domU using kpartx

kpart -va /dev/path/to/your/LVM/domU

mount /dev/mapper/.../....       /path/where/to/mount

vim //path/where/to/mount/boot/grub/grub.cfg

add nouveau.blacklist=1 to the module line.

Umount  /path/where/to/mount

kpart -vd /dev/path/to/your/LVM/domU

boot your domU

Install NVIDIA driver.

Hi,

How do I stop lightdm display manager and X.org server in Ubuntu
    11.10 and unload the nouveau vga driver?

I can run "sudo killall lightdm" and lightdm and X.org X server will
    be terminated successfully, but I cannot force nouveau to unload at
    all. It always say nouveau module is in use even if I use "sudo
    modprobe --force --remove nouveau".

I need to unload the following kernel modules for successful Xen VGA
    passthrough.

rmmod nouveau rmmod ttm rmmod drm_kms_helper rmmod drm Please read Deactivating
KMS and unloading Nouveau at
http://nouveau.freedesktop.org/wiki/KernelModeSetting
But setting "echo 0 > /sys/class/vtconsole/vtcon1/bind" causes the
display to hang and I can''t do anything more at all.

I can''t force nouveau,ttm,drm_kms_helper,drm kernel modules to unload.
Help!!! Also, if I add xen-pciback.hide=(01:00.0) to the module line in GRUB2,
the display turns blank while booting and I can''t do anything at all.
Any ideas? Thank you very much. Yours sincerely, Teo En Ming (Zhang Enming)

Re : Re : Re : Xen VGA Passthrough Questions

You need to add nouveau.blacklist=1 in the module line of grub.cfg


To do for a domU
===========

Have access to partition table of your domU using kpartx

kpart -va /dev/path/to/your/LVM/domU

mount /dev/mapper/.../....       /path/where/to/mount

vim //path/where/to/mount/boot/grub/grub.cfg

add nouveau.blacklist=1 to the module line.

Umount  /path/where/to/mount

kpart -vd /dev/path/to/your/LVM/domU

boot your domU

Install NVIDIA driver.

Hi,

How do I stop lightdm display manager and X.org server in Ubuntu
    11.10 and unload the nouveau vga driver?

I can run "sudo killall lightdm" and lightdm and X.org X server will
    be terminated successfully, but I cannot force nouveau to unload at
    all. It always say nouveau module is in use even if I use "sudo
    modprobe --force --remove nouveau".

I need to unload the following kernel modules for successful Xen VGA
    passthrough.

rmmod nouveau rmmod ttm rmmod drm_kms_helper rmmod drm Please read Deactivating
KMS and unloading Nouveau at
http://nouveau.freedesktop.org/wiki/KernelModeSetting
But setting "echo 0 > /sys/class/vtconsole/vtcon1/bind" causes the
display to hang and I can''t do anything more at all.

I can''t force nouveau,ttm,drm_kms_helper,drm kernel modules to unload.
Help!!! Also, if I add xen-pciback.hide=(01:00.0) to the module line in GRUB2,
the display turns blank while booting and I can''t do anything at all.
Any ideas? Thank you very much. Yours sincerely, Teo En Ming (Zhang Enming)

Re : Re : Re : Re : Xen VGA Passthrough Questions

My domU Windows XP works perfectly with changeset 25070

Did you read http://wiki.xen.org/wiki/Xen_VGA_Passthrough carefully?

As noticed in your document I am not used to compil my kernel using 


make world

I''ve got a doubt about building your kernel this way, your kernel will
have all required support for VGA PassThrough

I''m used to compil from 3.1.10


Extract from documentation on Wiki


=========
Xen VGA passthru requirements from dom0 kernel 
Make sure your dom0 Linux kernel has "CONFIG_XEN_PCIDEV_BACKEND_PASS"
option enabled. "CONFIG_XEN_PCIDEV_BACKEND_VPCI" should be disabled.
For example Debian Squeeze 2.6.32 kernel has the wrong PCIDEV_BACKEND 
mode as a default.. so in that case you might need to recompile the 
kernel with custom .config to get the right backend mode in use. 
BACKEND_PASS mode means the PCI IDs of the PCI device (graphics card) 
will be the same in the VM as in dom0/host.
==============

So you need to download kernel 3.3 sources and compil it properly.

Tonight (EST Time so in more than 8 hours ) I will have a try for kernel 3.3 and
see if I have the same error an will let you know.

Dear David Techer,

Thank you for your reply.

I am using Windows XP / Windows 8 Consumer Preview HVM domU and not
    Linux HVM domU.

Please read my Xen VGA Passthrough - Version 1.0.PDF and see whether
    I am missing out or making any wrong steps.

Yours sincerely,

Teo En Ming (Zhang Enming)

Windows XP......OK

Windows 2008...KO


2008 is based on Vista. It may not work for NVIDIA. (ATI should work).


I will not waste my time to help you if you don''t take into account
these informations.

Dear David Techer,

Thank you for your reply.

I am already using Linux Kernel 3.3.0 final.

I will be making changes to my compilation steps for Xen
    4.2-unstable changeset 25070.

Let''s see how.

Yours sincerely,

Teo En Ming (Zhang Enming)

"CONFIG_XEN_PCIDEV_BACKEND_VPCI" should be disabled. For example
Debian Squeeze 2.6.32 kernel has the wrong PCIDEV_BACKEND mode as a default.. so
in that case you might need to recompile the kernel with custom .config to get
the right backend mode in use. BACKEND_PASS mode means the PCI IDs of the PCI
device (graphics card) will be the same in the VM as in dom0/host.

And now install NVIDIA drivers and let me know if it is a real success.

Reboot your domU, when logged open your Device manager, use the scroll-bar OR
open Internet Explorer, use the the scrollbar.

Let me know if you don''t have any freeze.

David.

Dear David Techer,

I have just had great success with Xen VGA Passthrough to Windows 8 Consumer
Preview HVM domU and Windows XP HVM domU with Xen 4.2-unstable changeset 25070
in Ubuntu 11.10 64-bit dom0.

I am using Linux kernel 3.3.0. I can observe that you are using
    Debian 6.0.2 from your blog. But I am using Ubuntu 11.10. My
    favorite distro.

Please read my latest documentation "Xen VGA Passthrough - Version
    1.1.pdf".

It is a great success, especially Xen VGA Passthrough to Windows 8
    Consumer Preview. Thank you for your blog.

Yours sincerely,

Teo En Ming (Zhang Enming)

"CONFIG_XEN_PCIDEV_BACKEND_VPCI" should be disabled. For example
Debian Squeeze 2.6.32 kernel has the wrong PCIDEV_BACKEND mode as a default.. so
in that case you might need to recompile the kernel with custom .config to get
the right backend mode in use. BACKEND_PASS mode means the PCI IDs of the PCI
