Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

#1: How is the Windows guest visualized (what/where is its display)?
My only experience with "graphical access" to KVM guests is via VNC, but that will not do it for gaming. So how is the guest visualized / what is its display? As far as I can understand from the thread people simply have a monitor connected directly to the graphics card which is passed through to the guest, is this understood correctly?

Correct.

This directly connected monitor can then have multiple inputs which can be changed on the monitor itself or one could use a display switch box.

I lost you there ... could you clarify?

#2: Any alternatives to #1?
In the thread I see a couple of discussions about copying the frame buffer of one graphics card to another, but all of them end with the poster saying it is just speculation and that it should be theoretically possible. Anyone who have succeeded with getting the video output from the guest into a window on the host via whatever method?

Afaik there are no generic solutions. I use steam in-house streaming every now and then, but it only works for some games and is not very fast.

#3: Are two powerful graphics cards needed?
Quite a few posters have two quite powerful graphics cards installed. Isn't one powerful graphics card enough (one to pass to the guest used for playing games) and a less powerful one for running the host displays?

One is enough. I use the integrated Intel GPU for the host and a powerful nvidia card for the guest.

#4: Is a dedicated sound card needed?
Do I need a dedicated sound card or can the host and guest share the onboard sound card?

You can share your onboard sound card. Either with passthrough (and thus only usable by the guest) or shared between host and guest.

#5: Requirements for CPU and mother board?
Is it (more or less) sufficient to select a CPU with Intel VT-d or AMD-Vi, and a matching mother board (supporting the CPU and Intel VT-d / AMD-Vi)?

In theory yes. In practice, there seem to be some mainboards that work better than others. see https://docs.google.com/spreadsheet/ccc … _web#gid=0

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

This is not your primary GPU now, is it? These things may change depending on your computer BIOS setup and PCIe slot location it is attached to.

Nope. Never was my primary. Intel IGP is my primary, used for Linux console.

The DMAR faults indicate they are blocking the 8970 from reading memory just below 128GB.  It seems like a safe assumption that you don't have a 128GB VM, so the IOMMU is probably doing it's job by preventing these.  Does the card still work on bare metal?  It is possible that a failed memory controller on the card could be generating these accesses.  Does the address remotely resemble the host or guest address of the device?  (lspci in the host, info pci/info mtree in the qemu monitor)  If you haven't already, a hard power cycle might be a good idea.

I haven't tested bare metal, will do. Hard power cycles do nothing. I'll get the lspci (what do you need specifically?, -vv?) and info pci/mtree.

Thanks,

Will

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Hi, aw

Is there any tutorial about how to use these tools? I want to help this topic too.

You'll find kvm_stat in the qemu source tree, here are some instructions:

https://docs.fedoraproject.org/en-US/Fe … 20s02.html

Tracing is similarly easy, but the report generated is massive and takes some skill to analyze:

http://www.linux-kvm.org/page/Tracing

Generally you'll want to run kvm_stat first to see what the heavy hitters are, then look in the trace output to try to figure out why they're being called.

There's a bit on perf here too:

http://www.linux-kvm.org/page/Perf_events

A simple place to start, especially if you're compiling your own qemu is to uncomment #define DEBUG_VFIO from hw/misc/vfio.c, recompile and test with that binary.  You will get a ton of initial output but once the OS drivers are running it should slow down considerably.  The output will never cease entirely though, all config space access will go through qemu and any of the quirks.  So long as you don't see more than around a dozen lines per second, vfio is probably not the bottleneck.

Thx, aw

I took several days to read throught these documents. But I think I am missing something. kvm_stat displays two columns of number, but what do they mean? The first document doesn't explain it. And I don't know what is the typical value for each counter... So when I type kvm_stat, I have no idea which counter is "abnormal". I think the knowledge gap is pretty large here...

I just meant that most people are looking for the guest to feel like it is just another application window on the host machine. They are trying to get as far away from dual boot as possible. So most people will probably choose a monitor with two inputs, one which can be connected to the host and one to the guest. That way they do not have a monitor whose sole purpose is to display the output of the guest; by selecting source on the monitor they can turn it into a secondary monitor for the host. Or if their monitor do not have two inputs maybe they invest in an vga/dvi switch which will let them switch between the input of the guest and host.

Afaik there are no generic solutions. I use steam in-house streaming every now and then, but it only works for some games and is not very fast.

I have a Thinkpad T420 laptop with Nvidia optimus technology (not intended to be used for this setup, just some perspective). There is a heap of trouble with having output on the display port and powersaving from the Optimus technology. One solution to get output on the display port is to "setup a virtual display on the Intel GPU (so it now have the internal display and one virtual), render all output on the Intel GPU and then copy the contents of the virtual display to the Nvidia GPU for output via the display port" (http://zachstechnotes.blogspot.co.at/2012/04/post-title.html , https://github.com/liskin/hybrid-screenclone).

Of course the Nvidia GPU and Intel GPU of the T420 is "connected" through the Optimus technology, but if it is possible to copy display content between them in an Optimus setup maybe setups exist for desktop computers which would allow the same thing. Of course this would not be a generic solution (like you said: no generic solution exist).

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

should i expect vga passthrough to work out of box with kernel 3.14 and qemu 2.0 or xen 4.4?

i have a 2x geforce 770 cards intel 4670 and asrock z87 extreme4

i'm new to linux and the closest i have got to success is with xenserver 6.2 and esxi 5.5 i get yellow triangle in device manager with error code 43 under windows 8.1 guest.
i did this guide step by step in arch linux with gnome and linux mint 16, and both times virt-manager window doesn't respond after starting guest with vga passthrough

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

@aw

Patches were just posted upstream to do lazy tracking of the debug registers.

Presumably you have to be running 3.14-rc4 or linux-next for those patches to apply cleanly?  I tried them on 3.13.2, and most applied, with a few failures I was able to fix manually, but I haven't tried compiling a kernel with them yet...  [EDIT] and that wouldn't work anyway.

Anyway, I'm not sure whether they apply to me in any case, as I don't have a Haswell processor, I have an IvyBridge. (4930K) 

Also, Is that hv-time option relevant at all? I currently use -cpu host.

@neona

Turns out I'm an idiot, and installed a different qemu at some point that was earlier in my path than the one from qemu-git.  Cleaned that out and sound works fine now.

Hey, thanks, turns out I'm the same sub-species of idiot; now my sound is working too!

It should help all Intel processors when the guest makes use of debug registers, it's not Haswell specific.  hv-time is a Hyper-V enlightened time source which is more efficient than other emulated time sources.  I saw an improvement of several FPS when using hv-time.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Hi everyone

I installed every package suggested in the 1st post by nbhs in order to get qemu working with vfio-pci option
and edited every config file.
Till now i compiled the kernel twice, the second time i did i took care that the following options were selected
as builtin and not module:

CONFIG_VFIO_IOMMU_TYPE1=y
CONFIG_VFIO=y
CONFIG_VFIO_PCI=y
CONFIG_VFIO_PCI_VGA=y

Vt-d is enabled in the efi setup.

This is my configuration:

MB:MSI Z77A-GD80
CPU: Intel Core I7-2600
RAM:16GB ddr3 1866
DISK:128GB SSD Sata 3
Primary GPU: Intel® HD Graphics 2000
Secondary GPU: Nvidia GTX 280 <-- Windows display

But when i try to launch qemu (after device passthrough with vfio-bind) i get this error:

qemu-system-x86_64 -enable-kvm -M q35 -m 8192 -cpu host -smp 6,sockets=1,cores=6,threads=1 -bios /usr/share/qemu/bios.bin -vga none -device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on

Hi everyone

http://pastebin.com/SZ9aMVhG

I also added intel_iommu=on, igfx=on, but this changed nothing.

You have:

[    0.000000] Command line: initrd=\initramfs-linux-mainline.img root=/dev/sda2 rw,intel_iommu=on,igfx_on

Change the comma between "rw" and "intel_iommu" to a space.

Sorry for the big dump. I don't see anything out of the ordinary, unless I'm being blind? I'm going to try and see if I can get the card to run in native Linux with the opensource drivers.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

For the moment, I'm actually giving up on using VT-d, and have switched to Windows as the host and Linux as a storage-only guest.  I'm tired of all those assertion failures and the need to suspend and resume the host for the guest to start.

Incidentally, before Borderlands patch, the VM gave a mere 25% of the bare-hardware performance (30FPS vs 120FPS). I haven't tried with the patches.

As for rendering to a window on the host, you'd essentially need something like Lucid Virtu MVP, with the emulated Cirrus card as the output device, rather than an Intel card.
On my system, the "Star Swarm" mantle demo can use the Radeon for rendering, while displaying the output on the Intel GPU.  Who knows... maybe you can do the same with the Cirrus!

For switching between host and guest, I'd actually recommend using a KVM switch, and passing through an actual USB controller.  I tried passing through a hub instead, but the only thing that got forwarded was the hub itself.

Edit: this seems to happen only if the Radeon isn't assigned as the primary video card (over the IGP). Once I told my motherboard's BIOS to set the PCI-E as the primary VGA, it seems to work fine natively. Going to see if I can translate this to a working VM again.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

I'm able to get it to work again by using pci-assign, not vfio anymore.

WTF.

Your graphics card has Address Translation Services (ATS), aka a device IOMMU.  That usually doesn't cause problems, but since you're seeing stray addresses and since pci-assign works, what happens if you hide it, using something like this:

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

For a long time i have had issues when trying to start the guest (win 8.1).

My problems where that the guest boot process would stop before it could finish, then it would hang there for a bit until the host qemu process stopped. In order to boot my guest i had to restart the host 1-2 times and it would work until next time i powered down my host. And then the reboot process had to be repeated.

I think i may have found a solution which i wanted to share in case other people was having this problem.

What i did was disable the "fast boot" option in the windows 8.1 guest, after that it has worked flawlessly for me (3 host reboots now).

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Thanks, were just the commas to prevent IOMMU from being enabled.

I attached a 2nd hdd with a windows install and it boots! This is the command line i use

qemu-system-x86_64 -enable-kvm -M q35 -m 8192 -cpu host -smp 6,sockets=1,cores=6,threads=1 -bios /usr/share/qemu/bios.bin -vga none -device ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1 -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on -device ahci,bus=pcie.0,id=ahci -drive file=/dev/sdb,id=disk,cache=none,if=virtio -usb -usbdevice host:1532:001c -usbdevice host:0e6a:6001 -device ich9-intel-hda,bus=pcie.0,addr=1b.0,id=sound0 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0

The GPU just gets passed-through finely, but i'm sure there is something else to tweak.

Anything I can do?

Dumb question, have you actually installed the driver for the device?  Coming from Linux I'm spoiled by adding a device and having it "just work".  Windows isn't that way and I forget that sometimes.  In fact, just last week I though there might be some problem assigning the XHCI controller from the B85 chipset to a Win7 guest, but it was just a matter of going to the Intel website and installing the driver.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Have you tried this:

I'll try this when I can.

Yep. Windows 8 has the driver which makes most if not all USB3 controllers work out of the box. I just tried a Windows native install and it seems like the USB3 card refuses to initialize there either (similarly to native Linux drivers), so I guess the card is bad.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

I`ve got problems with my sound again - it just randomly stopped working....
On the Log I get these entries:

/etc/gdm/Xsession[915]: pulseaudio: pa_context_connect() failed

I created a different VM with ubuntu where the sound worked. After I executed it as root it showed the same behaviour as the windows vm... Do you know what could be going wrong?

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

Using latest kernel/qemu from OP. Getting this error.

qemu-system-x86_64: hw/pci/pcie.c:240: pcie_cap_slot_hotplug_common: Assertion `((pci_dev->devfn) & 0x07) == 0' failed.

It boots fine after downgrading to qemu-git-2.0.r30691.g91abb80-1-x86_64.pkg.tar.xz.

Note that it errors when downgrading, because of the custom SeaBIOS file. I deleted /usr/share/qemu/bios.bin, downgraded, then reinstalled my SeaBIOS package.

You need this fix for the assertion :

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9

I put in a second graphicscard and tested it again.
The good thing is. I had no problems to pass it to the VM... have seen the bios of the Card + seabios on the screen + Windows was booting (was booting to system repair, but I think that's because of other storage type)

The bad thing is, that both graphicscards are in the same iommu-group + 2 PCI-Controller 01.0 and 01.1. Think that is because my 2 PCIe Ports share share the 16 lanes, that are normally used by the first port.
So I think I will be abled to pass the card to the VM, but can't really use the primary card for Linux and I have to wait to get the Intel as Primary working ...

personally I would look to move primary (i.e. used by hardware own BIOS) graphics card to slot which does not share IOMMU group with the other one .... if that excludes all 16 lanes slots, there is at least one which will fit into X1 slot

RIght now im passing through my primary card (radeon 6950) what i did was, use pci-stub to bind it at boot and i disabled the efifb framebuffer with video=efifb:off on my grub cmdline
