Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Firstly, cheers for the tutorial. That must have taken awhile to write, and the effort is appreciated.
I've been looking into setting up a VGA passthrough setup under Xen for my next build for awhile now. I'm trying to work out what the advantages of this setup are over a setup under Xen. From what I've seen thrown around in different places, the main advantages are:
a less hacky setup for the passthrough, requiring less patches (once all this stuff gets released)
better support for NVIDIA cards? I've seen a few people say this, but nothing official to confirm it.
KVM receives more support than Xen, mainly due to Red Hat
Xen has a (relatively small) impact on the speed of the host, whereas KVM has no impact
not having to mess around with xl vs xm under Xen
Am I missing anything? I've seen a lot of people getting excited about using KVM over Xen for VGA passthrough, but not many people saying why they are so excited.

Yes, xen only officialy supports quadro cards, everything else requires hacks, that might or might not work, its not in the main xen tree, and its not being maintained/developed, while effort (still experimental) on kvm/qemu is being made to support
non-professional gpus out of the box.
Also, a little outdated but still relevant:
http://chucknology.com/2012/02/02/kvm-i … en-is-not/
EDIT: Forgot to add, all the hacks needed to get vga passthrough on xen, only work on the old "qemu-dm" (qemu 0.10.2) code they ship with, which is like 3-4 years old if i'm not mistaken, so things like audio passthrough wont work on windows x64 for example.

Yeah, I remember reading about the old version of qemu, and I think I may have read that article before (the diagrams looks familiar). The comments on the article are really hostile though, but as far as I understand, it's a pretty accurate portrayal of KVM vs Xen.

Audio:
Emulated audio was stuttery. My best results were with QEMU_AUDIO_DRV=alsa and QEMU_AUDIO_TIMER_PERIOD=0. AC97 was better than HD Audio for me, although I had to manually download Realtek's AC97 driver and force it in Add New Hardware (Intel's AC97 driver caused a guest BSoD). I think the PCI IDs are slightly off and Windows doesn't recognize the AC97 device automatically.I'm going to pass through a real sound card device for better audio (and lower CPU usage). Unfortunately, the chipset audio device is tied to other important devices, and the second video card covers up the only PCI slot I have, so I need to buy a PCI Express one.
I would suggest for going for a "native PCIe" sound card like the Soundblaster Z, most of the newer Auzentech stuff, ASUS "Phoebus" (not the other ASUS stuff) or any other brand that uses a PCIe chipset and not a PCIe to PCI bridge. I have spent a long time trying to get my PCI sound card passed through to a VM and have now given up on it.
With the card in my mobo PCI slot (ASMedia PCIe to PCI bridge in the same IOMMU group as all the non-intel stuff on the board) the sound card didn't play nice with intel_iommu=on, hard locking the system whenever it was initialised. I then put it in a PLX 8111 PCIe to PCI card in a 1x slot and got drivers fully installed on the passed through guest but no sound in the guest and it was doing weird stuff to my system. The PLX 8111/8112 bridge is generally what is used by those older "non native" PCIe sound cards.
Passing through the onboard sound was no problem but now I am looking to get a proper PCIe sound card.

Are you using my packages from the "radeon related problems" section?

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Yes, the qemu 1.5 and linux-mainline packages. But I tried with linux-ck from aur with VFIO enabled before and it didn't work, too.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
I applied both (except I use syslinux instead of grub), but still same result. I think I'll enabe DEBUG_VFIO as detailed here: https://lists.gnu.org/archive/html/qemu … 00432.html next, does this make sense?
edit: I think the second graphics card's spins up when I try to start qemu, but it's really quiet, so I'm not 100% sure.

Sure but you should report it on qemu-devel, seeing your mobo is very similar to mine i dont see any reason it shouldnt work, have you try to disable the nvidia and nouveau modules? changing pcie ports? laoding you rom by file? swapping cards? you could also pass it through using pci-assign instead of vfio-pci like https://bbs.archlinux.org/viewtopic.php … 3#p1274453
EDIT: you can find your card rom here http://www.techpowerup.com/vgabios/ or dump it via sysfs

I disabled the radeon module (because I try to forward the Radeon card to the guest) and loading the graphics card rom (dumped via "echo 1 > cat /sys/bus/pci/devices/0000:06:00.0/rom ; cat /sys/bus/pci/devices/0000:06:00.0/rom > vgabios-5670.rom) with the additional parameters "rombar=0,romfile=/root/vgabios-5670.rom," to the -device directive. I'll try pci-assign now and swap the cards later (both physical and "logical" (try to pass the GeForce through)). If it still doesn't work after that, I'll take a break, recompile the kernel and report to qemu-devel.
PS: the radeon hd 5670 doesn't support triple monitors, or does it?

What im saying is trying to disable every driver: radeon, nvidia, nouveau so we can discard that as a factor even though you're only passing through the radeon.

No idea

So how would I start qemu then? Do I still have terminal without nouveau or nvidia or do I have to use ssh?

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Yes, you'll have a terminal
if you use pci-assign you'll need to bind the gpu and the gpu snd to pci-stub instead of vfio-pci

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Ok, so I'm on 3.10 rc2 now and with vfio-pci the radeon card displays the seabios menu but as soon as a bootloader (grub, isolinux, the windows installer cd thing) trys to display something the screengoes black (but seems to stay on). Furthermore, qemu is telling me this:
qemu-system-x86_64: Attempt to reset PCI bus for VGA support failed (Inappropriate ioctl for device). VGA may not work.With the nvidia card passed through it says something about not being able to reset it (and some other strange things happend, like only output on the first launch, but I want the nvidia for the host anyway…).
edit: I think I read somewhere in this thread, that windows didn't boot for you with a newer seabios version and something about out of sync repositories, could you tell me which version you're using (I'm on rel-1.7.2-86-gf465e1e)?
edit2: ok I looked at http://git.qemu.org/?p=seabios.git;a=summary and the last change was a few months ago, so we should have the same seabios version (I used your pkgbuild, but if they had changed the repository…)

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Thanks for the guide! Worked great on my system, better than the Xen passthrough I had been using. I still haven't managed to make the emulated audio work without distortion, but as I had the same problem with Xen I bought a usb soundcard to pass through, which works very well.
I do have a small tip for improving the guide - rather than blacklisting modules, you can use 'softdep' instead to make pci-stub load before radeon/nouveau/etc. To use it, add this to a .conf file under /etc/modprobe:
softdep radeon pre: pci-stub
Replace radeon with your driver. Now add pci-stub to MODULES in /etc/mkinitcpio.conf and run mkinitcpio to regenerate the image. That's it!
I needed this instead of blacklisting because I actually have two radeon cards, one for the host and one for the VM, so just outright blacklisting radeon would have left me with no drivers for the host's card.

This might happen if you're mixing packages, for example qemu 1.5 from "radeon related packages" and a not patched kernel, since my qemu 1.5 package contains code to do a pcie bus reset, you'll have to patch kernel 3.10-rc2 or use my patched linux-mainline build, this code is not yet on the main qemu/kernel tree.
the code is from
git://github.com/awilliam/linux-vfio.git vfio-vga-reset
git://github.com/awilliam/qemu-vfio.git vfio-vga-reset read http://qemu.11.n7.nabble.com/VFIO-VGA-t … 01483.html
With the nvidia card passed through it says something about not being able to reset it (and some other strange things happend, like only output on the first launch, but I want the nvidia for the host anyway…).
Same with my nvidia card, but your problem on second launch might be related with what i mentioned before
You can use this patch for 3.10-rc2 in combination with my qemu 1.5 package:

NIce!, can you mention your setup?
Im using 2 radeon cards too, and im using pci-stub, i mentioned it in the guide.
softdep radeon pre: pci-stub
wont that bind both cards to pci-stub?
EDIT: Nvm i think i understand now, tnx for the info

AMD FX-4170 CPU
Gigabyte GA-990FXA-UD3 motherboard
16GB DDR3-1600 RAM
Radeon 6850 - Host
Radeon 7770 - VM
This usb soundcard for the guest: http://www.amazon.com/gp/product/B001MS … UTF8&psc=1 (it actually has a bug where it sounds awful by default, but if you set the output sampling rate to 48khz instead of 44.1khz it becomes perfect)
3 ssds (various kinds and sizes), one for host, one for guest os, one for guest game storage.
Using the patched kernel/qemu/seabios from your first post.
Here's the script I use to launch the VM: https://dl.dropboxusercontent.com/u/147 … /gaming.sh
Im using 2 radeon cards too, and im using pci-stub, i mentioned it in the guide.
How did you avoid having both blacklisted? It's not clear from your guide what, if anything, had to be done. I just copied over this trick from my prior xen setup and didn't try blacklisting at all.
softdep radeon pre: pci-stub
wont that bind both cards to pci-stub?
No, because the two cards are different and have different pci ids, so pci-stub will only bind the one whose id was given to it in pci-stub.ids. This would presumably break if your cards were identical however.

first i added pci-stub to mkinitcpio.conf
then i binded my card to pci-stub like this

pci-stub.ids=1002:6719,1002:aa80My card gets binded to pci-stub at boot

Ah, and your radeon isn't in mkinitcpio.conf, so it loads later and only claims the cards pci-stub hasn't? Basically the same effect as my method then, just without the explicit dependency. I needed the dependencies under xen because I was also passing through a USB controller and the USB modules were all getting loaded in the initrd before I could load xen-pciback (the xen equivalent to pci-stub), so I found softdep as a workaround. It's still useful here though, because I now also can have radeon in initrd so I get early KMS.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
since qemu 1.5 released
is it possible to make vfio based vga passthru without patching (either qemu or its seabios)?
