Hm. Looks like I spoke a little too soon.
Rebooted, and tried to dettach my card again so I could give it to the Vm.
When i dettach 1:00.0 it's fine, but on 1:00.1 it hangs.

Code:
[nyxcharon@dom0 ~]$ sudo xm pci-list-assignable-devices 
[sudo] password for nyxcharon: 
[nyxcharon@dom0 ~]$ sudo virsh nodedev-dettach pci_0000_01_00_0
Device pci_0000_01_00_0 detached

[nyxcharon@dom0 ~]$ sudo virsh nodedev-dettach pci_0000_01_00_1
Code:
[nyxcharon@dom0 ~]$ sudo xm dmesg
[sudo] password for nyxcharon:

Tried adding to the grub entry to no avail.:

Suggestions? Not sure why the audio portion of my card is refusing to work with me now...
The only thing that changed is I switched the DE to xfce, but I can't see how that matters...

For the changes in /etc/default/grub to become effective, you need to run update-grub in Ubuntu/Mint, dizzy4 uses this for Fedora:
Code:
grub2-mkconfig > /boot/grub2/grub.cfg

EDIT: Actually, you SHOULD be able to detach the pci devices 01.00.0 and 01.00.1 within grub, since Fedora should have pciback compiled into the kernel. See here http://wiki.xen.org/wiki/Xen_PCI_Passthrough#Static_assignment_for_built-in_xen-pciback for instructions.

If you can't detach the graphics card (audio) with virsh or via grub, you may want to try the pciback script here:
Code:
#!/bin/sh
    #
    ### BEGIN INIT INFO
    # Provides: pciback
    # Required-Start: $local_fs
    # Required-Stop: $local_fs
    # Should-Start:
    # Should-Stop:
    # X-Start-Before: xend
    # X-Stop-After:
    # Default-Start: 2 3 4 5
    # Default-Stop:
    ### END INIT INFO

    . /lib/lsb/init-functions
    scriptname=/etc/init.d/pciback
    configfile=/etc/xen/pciback.conf

    unbind() {
    # Unbind a PCI function from its driver as necessary
    [ ! -e /sys/bus/pci/devices/$1/driver/unbind ] || \
    echo -n $1 > /sys/bus/pci/devices/$1/driver/unbind
    }

    bind() {
    # Add a new slot to the PCI Backend’s list
    echo -n $1 > /sys/bus/pci/drivers/pciback/new_slot
    # Now that the backend is watching for the slot, bind to it
    echo -n $1 > /sys/bus/pci/drivers/pciback/bind
    }

    case $1 in

    start)
    cat $configfile | while read line;do
    echo $line | grep ^# >/dev/null 2>&1 && continue
    unbind $line
    bind $line
    done
    ;;

    stop|status|restart|force-reload)
    # As we don’t know which driver was bound before, there is not much we can do here
    ;;

    *)
    echo “Usage: $scriptname start” >&2
    exit 3
    ;;

    esac
save it in /etc/init.d and make it executable. Run
Code:
update-rc.d pciback defaults 21 19
for Ubuntu/Mint or "chkconfig" (check for exact syntax) for Fedora to edit the Sys V runlevel.

Then create the config file for the script:
Code:
# This file contains the list of pci(e) devices the pciback driver should bind
    # to at system startup.
    # Please provide the devices in long BDF notation.
    # Example:
    # 0000:08:00.0
    # NO EMPTY LINES!
    #
    0000:01:00.0
    0000:01:00.1
and save it as pciback.conf under /etc/xen/.

Finally edit the /etc/modules file and add on a separate line:
Code:
xen-pciback passthrough=1

After you reboot the PC the graphics card should be detached and available for the Windows domU. Check with xm pci-list-assignable-devices.

The script and /etc/modules entry make it permanent, that is each time you boot your graphics card 01.00.0 / 01.00.1 will be available for Windows (or another domU).

I don't know if and how the procedure described by dizzy4 using virt-manager detaches the PCI devices after the next reboot?

Good luck! I'm sure you will eventually iron out these things and get a rock-solid Windows virtual gaming (or whatever) machine, with all the goodies of Linux and Xen.

See here http://wiki.xen.org/wiki/Xen_PCI_Passthrough#Static_assignment_for_built-in_xen-pciback for instructions.

Please try this first!

So i tried both to no avail.

I attempted to modprobe pciback, can't find it.
Code:
[nyxcharon@dom0 ~]$ sudo modprobe pciback
FATAL: Module pciback not found.

After trying that script, I noticed in the startup it failed, told me to check this:
Code:
[nyxcharon@dom0 ~]$ systemctl status pciback.service
pciback.service
          Loaded: loaded (/etc/rc.d/init.d/pciback)
          Active: failed (Result: exit-code) since Tue, 13 Nov 2012 07:17:58 -0500
         Process: 801 ExecStart=/etc/rc.d/init.d/pciback start (code=exited, status=1/FAILURE)
          CGroup: name=systemd:/system/pciback.service

Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.

Running it myself, I get this:
Code:
[nyxcharon@dom0 ~]$ sudo /etc/rc.d/init.d/pciback start
[sudo] password for nyxcharon: 
/etc/rc.d/init.d/pciback: line 15: /lib/lsb/init-functions: No such file or directory

Being curious, I just commented it out to see what happened.
I get this:
Code:
[nyxcharon@dom0 ~]$ sudo /etc/rc.d/init.d/pciback start
/etc/rc.d/init.d/pciback: line 27: /sys/bus/pci/drivers/pciback/new_slot: No such file or directory
/etc/rc.d/init.d/pciback: line 29: /sys/bus/pci/drivers/pciback/bind: No such file or directory

At which point it just hangs. So, I'm having a couple issues now. tongue.gif
I still can't figure out why It just stopped working for no reason.

Not sure what is the best approach to take at this point.

Edit: Also noticed this:
Code:
[nyxcharon@dom0 ~]$ systemctl status systemd-modules-load.service 
systemd-modules-load.service - Load Kernel Modules
          Loaded: loaded (/usr/lib/systemd/system/systemd-modules-load.service; static)
          Active: failed (Result: exit-code) since Tue, 13 Nov 2012 07:33:16 -0500
            Docs: man:systemd-modules-load.service(8)
                  man:modules-load.d(5)
         Process: 404 ExecStart=/usr/lib/systemd/systemd-modules-load (code=exited, status=1/FAILURE)
          CGroup: name=systemd:/system/systemd-modules-load.service

Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.
[nyxcharon@dom0 ~]$ sudo /usr/lib/systemd/systemd-modules-load 
[sudo] password for nyxcharon: 
Failed to find module 'xen-pciback passthrough=1'

I have a file named pciback.conf in /etc/modules-load.d/

One final thing I found weird.
Code:
[nyxcharon@dom0 ~]$ sudo xm pci-attach win7a 01:00.0
Error: pci: improper device assignment specified: pci: 0000:01:00.1 must be co-assigned to the same guest with 0000:01:00.0, but it is not owned by pciback or pci-stub.
Usage: xm pci-attach [-o|--options=<opt>] <Domain> <domain:bus:slot.func> [virtual slot]

Insert a new pass-through pci device.
[nyxcharon@dom0 ~]$ sudo xm pci-attach win7a 01:00.1
Error: pci: PCI Backend and pci-stub don't own device 0000:01:00.1
Usage: xm pci-attach [-o|--options=<opt>] <Domain> <domain:bus:slot.func> [virtual slot]

Insert a new pass-through pci device.
Am I missing something here?

About "sudo modprobe pciback" - module not found:

I edited my reply above (and posted another one). If I'm not mistaken, Fedora has pciback in the kernel, so you don't need to load the module. Just in case, the command to load the pciback module is "sudo modprobe xen-pciback". To check if it's loaded as a module, run "lsmod | grep pciback" , the output should be "xen_pciback".

About: $ systemctl status pciback.service
pciback.service
Loaded: loaded (/etc/rc.d/init.d/pciback)
Active: failed (Result: exit-code) since Tue, 13 Nov 2012 07:17:58 -0500
Process: 801 ExecStart=/etc/rc.d/init.d/pciback start (code=exited, status=1/FAILURE)
CGroup: name=systemd:/system/pciback.service

and

sudo /etc/rc.d/init.d/pciback start
[sudo] password for nyxcharon:
/etc/rc.d/init.d/pciback: line 15: /lib/lsb/init-functions: No such file or directory

My mistake. I totally forgot that Fedora might use different paths etc., so the script must be adapted to Fedora. Unfortunately I'm not familiar with Fedora, sorry.

In addition, if Fedora uses pciback compiled into the kernel there is no need for editing the /etc/modules file to add xen-pciback... I believe this error:

Failed to find module 'xen-pciback passthrough=1'

points to it.

Error: pci: improper device assignment specified: pci: 0000:01:00.1 must be co-assigned to the same guest with 0000:01:00.0, but it is not owned by pciback or pci-stub.

This means it (0000:01:00.1 - the audio part) hasn't been detached. The Xen wiki explains it much better than I can: http://wiki.xen.org/wiki/Xen_PCI_Passthrough#Preparing_a_device_for_passthrough

Yes, it is confusing sometimes, and I apologize for having caused more confusion. Here are some links that might be useful:

https://fedoraproject.org/wiki/How_to_debug_Virtualization_problems#PCI_device_assignmen
http://tavi-tech.blogspot.co.il/2012/03/vga-passthrough-with-kvm-on-fedora-16.html - see 7.1. for some hints, though this one is for KVM.
http://xen.1045712.n5.nabble.com/PCI-Passthrough-td5711612.html - talks about problems with newest Fedora release / kernel and your graphics card, but not sure it's very helpful.
http://wiki.xen.org/wiki/Comprehensive_Xen_Debian_Wheezy_PCI_Passthrough_Tutorial - yeah, it's Debian, but very detailed.

By the way, did you blacklist the ATI driver? It might be the ATI graphics card driver under Linux that gets in the way with detaching your card.

What does
Code:
lspci -k

give you? Any driver assigned to the graphics card you try to pass through?

What's the next step boss? tongue.gif
Thanks for all the help so far. thumb.gif


EDIT:
So, found a "workaround"
Boot into gnome3, dettach the card (both 01:00.0 and 01:00.1)
Log out, log into xfce. Dettach the card again. Re-assgn to the VM.
Boot VM

No idea of why this works. I thought it might have something to do with gnome services, so I checked that startup box for them in Xfce, but that didn't help at all. But hey, if it works it works tongue.gif

Sidenote: Is it possible to passthrough my motherboard audio? If not, i'll just go the cheap soundcard route as mentioned before.
Nevermind. Passed through my audio from my motherboard with no problems, just had to do it from gnome3. tongue.gif

For those curious, it's
00:1B:0 Panther Point High Definition Audio Controller
Looks like I made a good choice of motherboard.

Wow, I love the creativity you are showing here! Seriously, I'd never tried booting into gnome3, detach graphic card, logout/login to xfce etc.

Your lspci -k shows that somethings not working with assigning 01.00.1 (audio) to pci-stub. Can you check that there is no mistake in the command that detaches 01:00.1 ?

For reference, here is my lspci -k output:
Code:
02:00.0 VGA compatible controller: NVIDIA Corporation GF106GL [Quadro 2000] (rev a1)
        Subsystem: NVIDIA Corporation Device 084a
        Kernel driver in use: pciback
        Kernel modules: nouveau, nvidiafb
02:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1)
        Subsystem: NVIDIA Corporation Device 084a
        Kernel driver in use: pciback
        Kernel modules: snd-hda-intel
My graphics card for passthrough to Windows is 02:00.0/1.
As you can see, I use pciback whereas you use pci-stub.

Have you blacklisted your ATI driver under Linux dom0?

I'm using the same command to dettach both, minus one having .0 and the other .1.
I'll try blacklisting the generic ati driver for fedora and see where that gets me.

Sidenote: So i can dettach my motherboard audio and pass it through to the vm. When I'm done with the vm, how can I re-attach it to my host again so I have sound?
I tried sudo xm pci-attach Domain-0 00:1b.0
The command attached it with no complaints, but i still have no sound

Tip: If you have some very bad mouse lag in your VM, I suggest chaging usb-device from mouse to tablet in your xen config. Worked wonders for me.
