[SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

Hello, I have an Arch with virt manager where I installed a small ArchVM. I have there the problem that picture and sound is asynchronous in Youtube videos. In a VM under VirtualBox and VMWare I do not have the problem.

I have installed in the VM: "qemu-guest-agent" and "spice-vdagent". I can also change the window of the VM and the resolution changes. The VM is otherwise quite fast.

As video driver I tried QXL or Virtio (with 3d acceleration). It does not bring any difference.

What do I have to set to watch well Youtube in a VM?

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

For clarity :
When using virtio driver you did verify virgl 3d was activated by looking at dmesg ?

Have you tried with vmware or std as vga guest driver ?

Post output of pacman -Qs xf86-video on guest please.

I don't know exactly what you mean, can I set "vmware" in Virt-Manager? I once changed to VGA in Virt-Manager and allocated 512MB (maximum) video memory. Now the resolution does not adjust automatically with the window size. The youtube video and a video with mpv is still asynchronous with the sound.

Ich weiß nicht ganz genau was du meinst, kann ich "vmware" in Virt-Manager einstellen? Ich habe mal in Virt-Manager auf VGA umgestellt und 512MB (maximum) Videospeicher zugewiesen. Jetzt stellt sich die Auflösung nicht mehr automatisch mit der Fenstergröße ein. Das Youtubevideo und ein Video mit mpv ist immer noch asynchron zum Ton.

Have a go at the manual: man --pager='less -p -vga\ \type' qemu

Ok, thanks. I'll take a look the next time. Maybe I can also add this to Virt-manager.

By the way, I use a Windows 10VM to play "The Settlers 4". The picture and sound are synchronous.

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

Getting virtio 3d acceleration to work requires some setting up, see https://wiki.archlinux.org/title/QEMU#virtio

[    2.878462] [drm] pci: virtio-vga detected at 0000:00:01.0

basic functionality of virtio is active, but there's no sign of a line with [drm] virgl 3d acceleration enabled so that part probably doesn't work .

Apart from the special setup, check virglrenderer is installed on the host.

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

Well, first of all I don't use '-vga vmware' second: I never used 'virtio 3d acceleration'
Though, it seems to work?? on my guest using these options:

-device virtio-vga-gl -display gtk,gl=on

After that calling dmesg for drm

[drm] pci: virtio-vga detected
[drm] features: +virgl +edid

But I don't get that specific message: 'virgl 3d acceleration enabled' ...

Loading the guest also provides this message(host)

gl_version 46 - core profile enabled
GLSL feature level 460

edit: my line is based on variables, changed that..;)

Question/s: does X start on the guest if you do not try to enable 'virtio 3d acceleration'?
I'll show you the command I used to start my guest, but, it runs from ISO not an HD-image!

qemu-system-x86_64 -boot order=d,menu=on,reboot-timeout=5000 -m size=3072,slots=0,maxmem=3221225472 -k en-us -name archlinux-lightdm-2022.06.21-x86_64.iso,process=archlinux-lightdm-2022.06.21-x86_64.iso_0 -device virtio-scsi-pci,id=scsi0 -device virtio-vga-gl -display gtk,gl=on -audiodev pa,id=snd0 -device ich9-intel-hda -device hda-output,audiodev=snd0 -device virtio-net-pci,romfile=,netdev=net0 -nedev user,id=net0,hostfwd=tcp::60032-:22 -machine type=q35,accel=kvm,usb=on,pcspk-audiodev=snd0 -global ICH9-LPC.disable_s3=1 -enable-kvm -device scsi-cd,bus=scsi0.0,drive=cdrom0 -drive id=cdrom0,if=none,format=raw,media=cdrom,read-only=on,file=/home/mark/archiso/iso-and-img/iso-img/archlinux-lightdm-2022.06.21-x86_64.iso -serial stdio -no-reboot

You can use your own tweaked 'run_archiso.sh' - that's what I do...
(see)https://gitlab.archlinux.org/archlinux/ … archiso.sh - why invent a new wheel if only the tires need air...;)

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

I have little time, so I can only answer now.

[drm] pci: virtio-vga detected
[drm] features: +virgl +edid
...
gl_version 46 - core profile enabled
GLSL feature level 460

This is what happens to me. But Virgl does not seem to be active.

> Question/s: does X start on the guest if you do not try to enable 'virtio 3d acceleration'?

How do you mean that? "not try to enable "virtio 3d acceleration"?" If I use:

> qemu-system-x86_64 -cdrom $cdr -boot order=a -drive file=$hdf,format=raw -m 8G -enable-kvm -machine q35 -device intel-iommu -cpu host

The vm starts fine.

I'll show you the command I used to start my guest, but, it runs from ISO not an HD-image!

I can not start your commado, I do not even know how to build a custom ISO. Someday I will learn. I am a noob. But I tried it with another ISO file:

>sh vmscript.sh D
>qemu-system-x86_64: -nedev: invalid option

I cannot find this option (-nedev) in the qemu manpage.



But by the way, I like qemu from the command line. It seems to start faster than via virt-manager.

There is no 'nedev' in my line, there is 'netdev' wink

Btw: if you execute 'glxinfo' in the guest you should see something similar to the next output:

To me that indicates 'virgl' is doing it's job, maybe someone can confirm that?

edit: use 'glxinfo -B' to get the above output immediately (see) man glxinfo

Yeah I made a mistake with that line 'nedev' I will paste the result in a few minutes!

Yes X starts.

That is also the case with me. Already from the beginning in Virt-manager. But according to Wiki should be:

[drm] virgl 3d acceleration enabled

@ Lone_Wolf does this work for you?

I don't like using virt-manager at all sad I very much dislike it kudos to anyone who is able to use that (in my eyes) POS...

I still like it. Just add USB devices (Webcam/ USB-Stick) to do video chats for work in M$ Teams or something. Add network cards... It's very quick and easy for me.

I wish there was the easy option to export the Qemu commando line from a Virt-Manager VM.

(And I have(!) to use Windows because the driver for my Logitech vf0770 webcam quite stupidly no longer works with new kernels. I used it many years with ubuntu and at least some months with arch. In a win10VM the webcam works)






But what this topic is about: Is the picture and sound of a Youtube video in sync in your VM?

And: Thank you for trying to help me. smile

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

That is also the case with me. Already from the beginning in Virt-manager. But according to Wiki should be:

[drm] virgl 3d acceleration enabled

It could be the message is old and the one you see now is the current(new)?

I like the terminal output... very interesting. I have to think over the options. smile

'man qemu' is your biggest friend here, everything is in there and there is a lot of info on other distro fora & wiki's - like Gentoo or RedHat F.I.

I still like it. Just add USB devices (Webcam/ USB-Stick) to do video chats for work in M$ Teams or something. Add network cards... It's very quick and easy for me.

I wish there was the easy option to export the Qemu commando line from a Virt-Manager VM.

(And I have(!) to use Windows because the driver for my Logitech vf0770 webcam quite stupidly no longer works with new kernels. I used it many years with ubuntu and at least some months with arch. In a win10VM the webcam works)

All these can be run (easily) with CLI options just start reading man pages and wiki's and you'll get there + it gives enormous insight!

edit: I remember this thread about running Windows10-Qemu-CLI, there is a lot of extra info too:

Thank you, but is the picture and sound of a Youtube video in sync in your VM?

It was a little discovery for me since I never use audio in my VM's, but yes, audio is definitely in sync with the footage.
And damn if I would want to use this all the time I'd pull out my hairs:(  I prefer metal for this.

edit: BTW. did you try to change the offset for the audio channel?
I wont guarantee it does 'anything' for you but it's worth a try I think

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

LOL. It just works when I add a sound card. Video and audio is in sync.

> qemu-system-x86_64 -cdrom $cdr -boot order=a -drive file=$hdf,format=raw -m 4G -enable-kvm -machine q35 -device intel-iommu -cpu host -device virtio-vga-gl -display sdl,gl=on  -device intel-hda -device hda-duplex

The problem really seems to be Virt-Manager.

Thank you very much!!!!!


Edit: The problem is not virt-manager but SPICE.

Re: [SOLVED] Youtube video in an Archlinux VM (Qemu/KVM) on an Arch hos

Short update: It is now syncron. I installed two more things on the host:

[2022-07-09T16:35:57+0200] [ALPM] installed libxvmc (1.0.13-1)
[2022-07-09T16:35:57+0200] [ALPM] installed xf86-video-intel (1:2.99.917+916+g31486f40-2)

The output of "sudo dmesg | grep drm" did not change in the VM.
