Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
aw wrote:Then either VGA arbitration is not working or QEMU can't read the ROM on the GPU. VGA arbitration not working was a problem we used to see using the proprietary nvidia driver in the host (driver would lock and never release the VGA arbitration lock). Nvidia might have fixed this, dunno. The latter ROM issue would produce an invalid ROM contents message in dmesg. GeForce cards do not work as secondary GPUs in the guest.
So is there any workaround or any way I can fix this?
If you read the FAQ from the link below, you might find Question 9 interesting. If you look at the comments, you'll find a link to that patch. It looks like even the latest version of the Linux nvidia driver still has this problem.

OK. After apt-get purge virtualbox* I did a restart and tried again - no change. In the meantime I read about MTRR and added some boot parameters. Here is my new dmesg:

That post has absolutely nothing to do with the zapping message. If you don't have a Quadro or GRID, real or fake, ignore everything about that post.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Anyone know how to fix this?
alsa: Requested buffer size 256 was rejected, using 2048if the buffer is too large, the audio quality in Windows VMs seems to suffer massively and it seems like alsa isn't letting me set a low buffer.
edit:
never mind, I forgot to use sudo -E and now it's using the buffer size I set in my .asoundrc

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
Hmm, any idea how can I share CPU between two guest, assuming that CPU load is equal to 100% on both guests and host:
Max allowed CPU usage for guest#1 - 40%
-- for guest#2 - 40%
-- for host - 20%
when guest#1 load is low, guest#2 is getting up to 80% of CPU usage and vice versa, host - always 20%.
Is this possible?
Also same thing, but with RAM.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
I've got information that NVIDIA Game Ready drivers turn off CUDA. Is this true? Can anyone confirm this?
The forum rules prohibit requesting support for distributions other than arch.
I gave up. It was too late.
What I was trying to do.
The reference about VFIO and KVM VGA passthrough.

google: cgroups
When device assignment is in play, VMs use fixed amounts of RAM, all guest memory is pinned, so maybe the only thing cgroups could control would be caching of block device in the host if they're setup to use host caching. cgroups for setting CPU limits should be possible.

VGA arbitration not working was a problem we used to see using the proprietary nvidia driver in the host (driver would lock and never release the VGA arbitration lock). Nvidia might have fixed this, dunno. The latter ROM issue would produce an invalid ROM contents message in dmesg. GeForce cards do not work as secondary GPUs in the guest.
So is there any workaround or any way I can fix this?
If you read the FAQ from the link below, you might find Question 9 interesting. If you look at the comments, you'll find a link to that patch. It looks like even the latest version of the Linux nvidia driver still has this problem.
I'm sorry, what link are you referring too? The one in your signature? I can't find a Question 9 on there?
Edit: Woops nvm I found it, i'll check it out because it seems to be my problem.
Edit 2: Well that went wrong... I've patched the host NVIDIA driver, installed it, and then it wouldn't boot anymore. Not even with nomodeset...
I had to switch back to the stock Arch kernel, add nomodeset, then reinstall the patched kernel + stock Arch drivers.
I can boot my system again but still without a patched NVIDIA driver.
Although i'm not sure Question 9 applies to me. They are talking about "nothing happening", while Qemu in fact launches for me, just not the VM itself.

That would be me.
Ah, I see you added me there as well, so let me provide some additional info:
- Host Distro: Arch
- Host Kernel: 3.17.6-1-ARCH
- Qemu version: 2.1.2
- Patches: None, just using standard Arch packages.
- Other remarks: Working guests: Mavericks / Windows 8 / Arch / Ubuntu 14.10

You can do it also for USB controllers integrated into the south-bridge since they are attached to PCIe root like normal extension cards. This is useful for all types of USB devices because it basically removes USB root complex from host OS and also removes latency of USB serialisation through qemu. Also perfect for attaching things like USB-DAC for great quality sound.
So I followed your advice with no luck, maybe I should focus efforts on USB Device Pass-through as it seems get further with Ubuntu.
For the record, the three USB controllers were:
00:14.0 USB controller [0c03]: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI [8086:8c31] (rev 04)
00:1a.0 USB controller [0c03]: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #2 [8086:8c2d] (rev 04)
00:1d.0 USB controller [0c03]: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #1 [8086:8c26] (rev 04)Added them to my /etc/vfio-pci.cfg
0000:00:14.0
0000:00:1a.0
0000:00:1d.0Then added the following lines to my qemu config
-usb \
-device vfio-pci,host=00:14.0 \
-device vfio-pci,host=00:1a.0 \
-device vfio-pci,host=00:1d.0 \Starting the Virtual Machine fails at the first controller with the following error.
qemu-system-x86_64: -device vfio-pci,host=00:14.0: vfio: error opening /dev/vfio/4: No such file or directory
qemu-system-x86_64: -device vfio-pci,host=00:14.0: vfio: failed to get group 4
qemu-system-x86_64: -device vfio-pci,host=00:14.0: Device initialization failed.
qemu-system-x86_64: -device vfio-pci,host=00:14.0: Device 'vfio-pci' could not be initializedAny suggestions?
ok so you are trying to add three USB controller devices (1x USB 3.0 at 00:14.0 and 2x USD 2.0 at 00:1a.0,00:1d.0) . Apparently adding USB 3.0 controller fails, although we do not see anything about the other two USB 2.0 controllers. Did you ensure you are passing whole IOMMU group? Did you remember to add vendorid:deviceid to pci-stub.ids=... in kernel command line? Did you try passing only USB 2.0 devices? I assume your host was restarted to allow for vfio to claim these USB controllers?
I was able to sucessfully pass USB devices by explicitly listing them by vendorid and productid. No kernel command is present, my issue was with proper syntax in my QEMU configuration.
I've noticed both the Host and Guest take control of the device at the same time once connected. Not too sure if this is normal, but once disconnected, the following error is displayed on the Host console:
libusb_release_interface: -4 [NO_DEVICE]
libusbx: error [_open_sysfs_attr] open /sys/bus/usb/devices/3-14/bConfigurationValue failed ret=-1 errno=2

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
AW, what did you do in regards to SELinux and Fedora 21? I spent the last 3 nights trying to get my working Arch XML to boot under Fedora 21, only to figure out/remember SELinux was enabled...
Also, to everyone, what did you do to get Windows 7 with EFI booted to run with more than one CPU? Are there more HyperV parameters that need to be set in my XML?

You'd need to actually tell me what selinux is complaining about to know how to fix it, not that I'm an selinux expert. However, if it's complaining due to a wrapper script being used to add the x-vga option, you can find instructions here to fix it: https://access.redhat.com/documentation … /virt.html If it has something to do with <qemu:arg> options, you're on your own.

I ended up disabling SELinux... But here are the two situations I ran into:
1) I had the OVMF files CODE and VARs in my home directory - these were from my working ARCH build. I went to start my VM and it said I had permission denied on the files, even with temporary chmod 777.
2) When I linked to the OVMF files in their default location, /usr/share/edk2.git/..., I wouldn't get the permissions denied, but the monitor attached to my passed-through wouldn't iniialize. I would hear the GPU spin up, the VM would say it's running, but no output. When I wasn't passing through my GPU, or any card, I would see the Tianocore efi screen on the virtual console.
Once I disabled SELinux, I ceased to have any of these issues. I should have thought of SELinux when I got the permission denied with the OVMF files set to 777.
In a post from 2013, you mentioned you had a Windows 7 VM running with GPU Passthrough. My issue I have is I cannot allocate more than one CPU to the VM. When I increase the Core and Thread count, it will get past the Tianocore screen, the Windows 7 logo will appear, then the screen will go black. I can even take my working Windows 10 config, swap my Windows7.img in, and the same issues will occur.

pebkac... why would libvirt have permission to files in your home directory? selinux rightfully prevents this

The OVMF CODE file can be linked to the default location, but the VARS file needs to live somewhere libvirt has access to write. If you use the template mechanism discussed in my KVM forum slides, libvirt will make the writable VARS file in /var/lib/libvirt/qemu/nvram/

I've only used Windows 7 with x-vga, it's only here that I learned win7 can even run on OVMF, but it seems like more hassle than I'm interested in for a game VM. IME, windows doesn't like hardware changes and uses a different internal machine type for a uniprocessor system versus a multi-processor system. You may need to boot w/ a single cpu, go into device manager and change the model before you can boot with multiple cpus. Sorry, that's as specific as I can be, it's been a long time since I've had to do that and I always install windows guests with at least 2 cpus to avoid it since.

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
As far as i understand it - windows 7 doesn't work properly with any OVMF config at all. It tries to boot and fails to output any graphics.
I'm not sure, but eventually i might test this behaviour (again) on real UEFI platform.
Debug console isn't saying anything suspicious when it hangs. I might fiddle with it using GDB, but i highly doubt that it'll help.

I have been able to patch 3.18.7 on Fedora for the ACS capabilities. I've taken Alex's patch and had to change it around a little - I reverse engineered it and applied it to the new quirks.c file. I posted the patch on this forum, search for pkim posts. I also posted a detailed experience with my setup as well - I almost got everything working stock, but I needed the ACS patch.

Of course, there was a quote like "do people talk about something except vga passthrough ion this channel anymore?" or something, but, you know..

I have been searching abit in this forum and on aw's vfio blog faq. When going through the talking points you had aw i got the impression that if i switch to using OVMF and UEFI on my windows8.1 guest, the vga arbiter issue with Nvidia proprietary host drivers is a non issue (your faq question 9) and i can install and use the nvidia driver on the host without patching?
Sorry if this question has been answered before i just had a hard time finding the answer that looked obvious from your talking points "VFIO, OVMF, GPU, and You ".

Re: KVM VGA-Passthrough using the new vfio-vga support in kernel =>3.9
I've seen this too (no need to patch host drivers if you're using OVMF). Sadly I have no clue how to make it work though.
From what I've read you should launch Qemu with
qemu-system-x86_64 -L .This while being in the directory where the UEFI bios.bin is in.
Well tried that, it did nothing, not even give me an UEFI shell.
Is there a proper guide to OVMF in Qemu out there that we can use?

Assuming you're on arch:
Get OVMF-svn, build an install it.
Then launch qemu like this:
qemu-system-x86_64 -enable-kvm -m 1024 -cpu host,kvm=off -smp 2,sockets=1,cores=2,threads=1 \
