Hello xen-devel,


This is my first post on this list and as such i might be breaking some
explicit/implicit rules and i apologize if it's the case. Maybe this list
isn't the exact right kind of place where to post this kind of stuff, but i
know lots of us are browsing this list as the primary source of
documentation for xen.

I've read many times windows 7 isn't the right os to run on top of xen.
Most of the guy's who are running vga passthru are recommanding to use
windows xp, and i've never seen any success report of vga passthru on
windows 7 so i thought it was important to post mine.

Anyway, here's my hardware setup :
- Gigabyte GA-990X-UD3
- AMD Phenom II X6 1075T Processor
- MSI Cyclone NVIDIA Geforce GTX 460

On the software side i'm using :

- Debian testing as Dom0
- Xen-4.1 (debian version 4.1.2-2) with what's now referred to as "Tobias
Geiger patches" (
http://old-list-archives.xen.org/archives/html/xen-devel/2010-05/msg00441.html)
(You have to edit the patches, changing the path to some qemu source files
for them to apply)
- debian's kernel  3.1.5, compiled to include the pciback driver. Here's
the output of `cat /boot/my3.1.5config | grep -i xen`
CONFIG_XEN=y
CONFIG_XEN_DOM0=y
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PVHVM=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set

CONFIG_PCI_XEN=y
CONFIG_XEN_PCIDEV_FRONTEND=m
CONFIG_XEN_BLKDEV_FRONTEND=m
CONFIG_XEN_BLKDEV_BACKEND=m
CONFIG_NETXEN_NIC=m
CONFIG_XEN_NETDEV_FRONTEND=m
CONFIG_XEN_NETDEV_BACKEND=m
CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_WDT=m
CONFIG_XEN_FBDEV_FRONTEND=y
# Xen driver support
CONFIG_XEN_BALLOON=y
# CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is not set
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=m
CONFIG_XEN_BACKEND=y
CONFIG_XENFS=m
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
CONFIG_XEN_XENBUS_FRONTEND=y
CONFIG_XEN_GNTDEV=m
CONFIG_XEN_GRANT_DEV_ALLOC=m
CONFIG_XEN_PLATFORM_PCI=m
CONFIG_SWIOTLB_XEN=y
CONFIG_XEN_PCIDEV_BACKEND=y

The kernel boot options are 'nomodeset xen-pciback.passthrough=1
xen-pciback.hide=(01:00.0)(01:00.1)'

- Here's my win7 domU config file :

kernel = "/usr/lib/xen-4.1/boot/hvmloader"
builder='hvm'
memory = 3072
name = "w7"
vif = [ 'type=netfront,bridge=xenbr0, mac=00:16:3e:35:49:62']
disk = [ 'phy:/dev/w7-xen/system,hda,w', 'phy:/dev/w7-xen/appz,hdb,w']
device_model = '/usr/lib/xen-4.1/bin/qemu-dm'
boot="dc"

pci=['01:00.0','01:00.1']
gfx_passthru=1

vcpus=6
acpi=1
sdl=0
vnc=1
vncconsole=1
vncpasswd=''
serial='pty'
usbdevice='tablet'
pae=1
pci_msitranslate=0
pci_power_mgmt=0
acpi_s3 = 1
acpi_s4 = 1
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
xen_platform_pci=1
hpet = 1
viridian=1
monitor=1
xen_extended_power_mgmt=2
hpet=1

What's important here for the Nvidia drivers to work and not give a nice
nvlddmkm.sys BSOD is:
pci_msitranslate=0
pci_power_mgmt=0

- Windows 7 32bits
- Nvidia drivers 275.33
- You have to manually run aero speed test or force aero to start by using
registry entries for the desktop not to be laggy

The windows 7 domU is running fine with no performance decrease noticeable,
although i've not yet played intensive gpu video game, i'm still pretty
confident they'll run fine.

Anyway. i've still some problems i shall report in separate posts :
- The PCI bus topology isn't preserved, and the gfx card, which is plugged
on 01:00 becomes 05:00 on domU.
- I'm passing through an RME Hdsp / hammerfall pci sound card to the domU
and while it is working fine on his own, there's a strange interaction
between it and the GPLPV network driver. When i start playing sound, the
network instantly cease working. It starts back as soon as i stop playing
audio.

That's all folks,

Cheers,
Lta

You could be my HERO of the day. 
However I have to wait monday to confirm that this works on my setup too,
since I'm not at home.

Maybe you just saved me from buying an ATI card. I'll let you know asap.
THANKS

I am going to test it in a couple hours when I am back to home.

If it works with xen 4.2, it should be very very interesting :)

I will let you know.

Thanks for the post! I'm sure it helps many people trying out this stuff.

Just a note that "gfx_passthru=1" makes the passthru physical graphics adapter
become *primary* in the guest VM.. the subject of the email says "secondary", 
so I wanted to clarify that :)

So these are the required 'magic' options..

I wonder if this is important aswell..

It seems you have hpet two times :)

Hmm.. I wonder why "xen-pciback.passthrough=1" doesn't work..

Could you tell me what version of Xen? 4.1.0? 4.1.2?

By the way could you send your patches attached to a mail so I could try?

Test on Xen 4.2 failed (desktop stays to lag...)

With installing xen 4.1.0/4.2.0 over my xen 4.2, domU boot but nothing appears on screen.

Strange.

Objet : [Xen-devel] Secondary VGA Passthrough, nvidia, win7: success report.
 

Hello xen-devel,


This is my first post on this list and as such i might be breaking some explicit/implicit rules and i apologize if it's the case. Maybe this list isn't the exact right kind of place where to post this kind of stuff, but i know lots of us are browsing this list as the primary source of documentation for xen.

I've read many times windows 7 isn't the right os to run on top of xen. Most of the guy's who are running vga passthru are recommanding to use windows xp, and i've never seen any success report of vga passthru on windows 7 so i thought it was important to post mine.

Anyway, here's my hardware setup :
- Gigabyte GA-990X-UD3
- AMD Phenom II X6 1075T Processor
- MSI Cyclone NVIDIA Geforce GTX 460

On the software side i'm using :

- Debian testing as Dom0
- Xen-4.1 (debian version 4.1.2-2) with what's now referred to as "Tobias Geiger patches" (http://old-list-archives.xen.org/archives/html/xen-devel/2010-05/msg00441.html) (You have to edit the patches, changing the path to some qemu source files for them to apply)
- debian's kernel  3.1.5, compiled to include the pciback driver. Here's the output of `cat /boot/my3.1.5config | grep -i xen`
CONFIG_XEN=y
CONFIG_XEN_DOM0=y
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PVHVM=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
# CONFIG_XEN_DEBUG is not set
CONFIG_PCI_XEN=y
CONFIG_XEN_PCIDEV_FRONTEND=m
CONFIG_XEN_BLKDEV_FRONTEND=m
CONFIG_XEN_BLKDEV_BACKEND=m
CONFIG_NETXEN_NIC=m
CONFIG_XEN_NETDEV_FRONTEND=m
CONFIG_XEN_NETDEV_BACKEND=m
CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_WDT=m
CONFIG_XEN_FBDEV_FRONTEND=y
# Xen driver support
CONFIG_XEN_BALLOON=y
# CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is not set
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=m
CONFIG_XEN_BACKEND=y
CONFIG_XENFS=m
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
CONFIG_XEN_XENBUS_FRONTEND=y
CONFIG_XEN_GNTDEV=m
CONFIG_XEN_GRANT_DEV_ALLOC=m
CONFIG_XEN_PLATFORM_PCI=m
CONFIG_SWIOTLB_XEN=y
CONFIG_XEN_PCIDEV_BACKEND=y

The kernel boot options are 'nomodeset xen-pciback.passthrough=1 xen-pciback.hide=(01:00.0)(01:00.1)'

- Here's my win7 domU config file :

kernel = "/usr/lib/xen-4.1/boot/hvmloader"
builder='hvm'
memory = 3072
name = "w7"
vif = [ 'type=netfront,bridge=xenbr0, mac=00:16:3e:35:49:62']
disk = [ 'phy:/dev/w7-xen/system,hda,w', 'phy:/dev/w7-xen/appz,hdb,w']
device_model = '/usr/lib/xen-4.1/bin/qemu-dm'
boot="dc"

pci=['01:00.0','01:00.1']
gfx_passthru=1

vcpus=6
acpi=1
sdl=0
vnc=1
vncconsole=1
vncpasswd=''
serial='pty'
usbdevice='tablet'
pae=1
pci_msitranslate=0
pci_power_mgmt=0
acpi_s3 = 1
acpi_s4 = 1
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
xen_platform_pci=1
hpet = 1
viridian=1
monitor=1
xen_extended_power_mgmt=2
hpet=1

What's important here for the Nvidia drivers to work and not give a nice nvlddmkm.sys BSOD is:
pci_msitranslate=0
pci_power_mgmt=0

- Windows 7 32bits
- Nvidia drivers 275.33
- You have to manually run aero speed test or force aero to start by using registry entries for the desktop not to be laggy

The windows 7 domU is running fine with no performance decrease noticeable, although i've not yet played intensive gpu video game, i'm still pretty confident they'll run fine.

Anyway. i've still some problems i shall report in separate posts :
- The PCI bus topology isn't preserved, and the gfx card, which is plugged on 01:00 becomes 05:00 on domU.
- I'm passing through an RME Hdsp / hammerfall pci sound card to the domU and while it is working fine on his own, there's a strange interaction between it and the GPLPV network driver. When i start playing sound, the network instantly cease working. It starts back as soon as i stop playing audio.

That's all folks,

Cheers,
Lta

I tested xen 4.1.2 too.Tobias patches are the patches I've tested. I am not very lucky.


Since you used Tobias patches as me, my question is - to be more precise - could you sent Tobias patches that you have modified in order to checking
I did not forget something as you. 


My idea is that since I already have xen 4.2 installed, installing xen 4.1.2 over this , something wrong happens


My screen stays like a black screen and nothing happens. no "gfx message" in the log.

With Xen 4.2 I tried aero desktop too but my domU crashes when  I tried to activate aero.

I tested xen 4.1.2 too.Tobias patches are the patches I've tested. I am not very lucky.


Since you used Tobias patches as me, my question is - to be more precise - could you sent Tobias patches that you have modified in order to checking
I did not forget something as you. 


My idea is that since I already have xen 4.2 installed, installing xen 4.1.2 over this , something wrong happens


My screen stays like a black screen and nothing happens. no "gfx message" in the log.

With Xen 4.2 I tried aero desktop too but my domU crashes when  I tried to activate aero.

Have u tried to force windows to activate the aero desktop ?

I also followed tobias (same as yours) instructions to dump and build vgabios-pt.bin into xen, did u do it also ?

Attached  are the  updated Tobias patches for Xen 4.1.2.

The most important is 01_pass-through.patch that need to be updated :) else you receive a stupid error from compilation


Since I compiled kernel 3.1.6, without modules for Xen (=Y), I have to remove 'xen-pci.passthough=1' from grub else I can not  have my screen (stays black...)


I am doing my test on a new domU Windows 7.

Hope it will succeed :)

I will let you know

I took the decison to stop my tests for xen 4.1.2 and VGA PassThrough.

Too much problem....with Windows 7. Moreoever I came to the conclusion that it is too more unstable than VGA PassThrough on Xen 4.2


Back  to Xen 4.2  :) with XP and Linux :). No windows 7

Attached  are the  updated Tobias patches for Xen 4.1.2.

The most important is 01_pass-through.patch that need to be updated :) else you receive a stupid error from compilation


Since I compiled kernel 3.1.6, without modules for Xen (=Y), I have to remove 'xen-pci.passthough=1' from grub else I can not  have my screen (stays black...)


I am doing my test on a new domU Windows 7.

Hope it will succeed :)

I will let you know

I tested xen 4.1.2 too.Tobias patches are the patches I've tested. I am not very lucky.


Since you used Tobias patches as me, my question is - to be more precise - could you sent Tobias patches that you have modified in order to checking
I did not forget something as you. 


My idea is that since I already have xen 4.2 installed, installing xen 4.1.2 over this , something wrong happens


My screen stays like a black screen and nothing happens. no "gfx message" in the log.

With Xen 4.2 I tried aero desktop too but my domU crashes when  I tried to activate aero.

Have u tried to force windows to activate the aero desktop ?

I also followed tobias (same as yours) instructions to dump and build vgabios-pt.bin into xen, did u do it also ?

Maybe this list isn't the exact right kind of place where to post this kind of stuff, but i know lots of us are browsing this list as the primary source of documentation for xen.
