Are these done on the guest or host? Is this still the best way to do this? I don't understand why they can't just offer these codecs for a few dollars. I would gladly pay it.Please, anyone following these steps, don't do this on a production machine and as mentioned, to maintain this, you have to reinstall your custom qemu every time proxmox updates.
I did post this in bugzilla as you requested.
I'm not very good at formatting things, but I have typed up the notes in textedit.
add the following to /etc/apt/sources.list
I use nano:
nano -w /etc/apt/sources.list
paste in
#deb http://deb.debian.org/debian/ bookworm-backports contrib main non-free non-free-firmware
deb-src http://ftp.us.debian.org/debian bookworm main contrib non-free non-free-firmware
keep the bookworm-backports commented out while you setup the build evironment for qemu because you don't want to get in a dependency loop with held back packages, etc.
after building, you can enable the bookworm-backports repo.
This will also update several installed packages.
When you're done with the build - you will want to update the mesa-va-drivers
apt update
apt build-dep qemu virglrenderer
apt install git build-essential
#### install the remaining packages needed for qemu build
apt install libacl1-dev libattr1-dev libglusterfs-dev libpci-dev libproxmox-backup-qemu0-dev libsdl1.2-dev libsystemd-dev python3-venv quilt xfslibs-dev lintian
cd /usr/src
git clone https://gitlab.freedesktop.org/virgl/virglrenderer.git
cd virglrenderer
meson build -Dvenus=true -Dvideo=True -Dprefix=/usr
If you have an amd gpu, you can add -Ddrm-renderers=amdgpu-experimental to the end of the meson build line
cd build
ninja install
Now you need to get the proxmox qemu source
cd /usr/src
git clone https://github.com/proxmox/pve-qemu
cd pve-qemu
git submodule update --init --recursive
cd qemu
meson subprojects download
###########################################
Patch the source from inside the pve-qemu/qemu directory
Patch file can be found here:
https://raw.githubusercontent.com/m...471b5bcab41842a5fe6ea9b05a09cb78f/virgl.patch
or copy/paste the code from @two56bytes post
Just wget it to the qemu directory.
root@enyo:/usr/src/pve-qemu/qemu# patch < virgl.patch
can't find file to patch at input line 5
Perhaps you should have used the -p or --strip option?
The text leading up to this was:

Now you will cd .. and run make deb
cd ..
make deb
dpkg -i pve-qemu-kvm_9.2.0-3_amd64.deb

update the mesa, libdrm2, etc installs
apt upgrade -t bookworm-backports
Sorry who is "they"?Are these done on the guest or host? Is this still the best way to do this? I don't understand why they can't just offer these codecs for a few dollars. I would gladly pay it.
Actually it uses Debian's package, so i don't think they charge any money, it must be a mistake. Otherwise why does Intel and other open source drivers have codecs built in?Proxmox.
Using these steps I was able to build qemu 10. Even though I have accelerated graphics in wayland on my VM i don't have access to the hardware codecshey folks its me again,
here i am using the most recent version of virglrenderer so the sources can be build from pve-qemu master branch,
enjoy!
1. update to proxmox 6.11 (not necessary)
apt update
apt install proxmox-kernel-6.11
reboot
2. install amdgpu for ubuntu noble (not necessary)
wget https://repo.radeon.com/amdgpu-install/6.3.4/ubuntu/noble/amdgpu-install_6.3.60304-1_all.deb
sudo apt install ./amdgpu-install_6.3.60304-1_all.deb
amdgpu-install -y --usecase=workstation,rocm
reboot
check if it is loaded
dkms status
3. Install mesa 24 (might be necessary)
Add bookworm-backports to /etc/apt/sources.list:
echo -n "deb http://deb.debian.org/debian/ bookworm-backports contrib main non-free non-free-firmware" >> /etc/apt/sources.list
then
apt update
apt install -t bookworm-backports mesa-va-drivers
4. build virglrenderer
Code:git clone https://gitlab.freedesktop.org/virgl/virglrenderer.git cd virglrenderer meson build -Dvenus=true -Dvideo=True -Dprefix=/usr cd build ninja install
check if it is loaded
ldd /bin/qemu-system-x86_64 | grep virgl
ls -lahrt /usr/lib/x86_64-linux-gnu/libvirglrenderer.so.1
5. build pve-qemu
git clone https://github.com/proxmox/pve-qemu
cd pve-qemu
git submodule update --init --recursive
cd qemu
meson subprojects download
6. patch
place virgl.patch into the qemu dir and patch file with
patch < virgl.patch

4. build & install & restart
Code:cd .. make deb dpkg -i pve-qemu-kvm_9.2.0-2_amd64.deb
reboot guest
PS. I'm using debian13 as the guest on a pve9 host and an amd ryzen apu.
PPS. I was able to get it working. Previously i intentionally left one step out - updating virglrenderer. Now I've updated that too and i succeeded!.
The reason I didn't want to build it manually was so that I can go back to the "upstream packages" at some point. Here's what I did:
I got the debian virglrenderer package source code from https://salsa.debian.org/debian/virglrenderer, compared with https://gitlab.freedesktop.org/virgl/virglrenderer.
It looked to me that only the debian dir was addoed so i copied that over.
Then i rebuilt the package - using the latest main.
Code:
mk-build-deps --install --tool "apt-get --yes --no-install-recommends"; dpkg-buildpackage -uc -us -tc -bI installed the packages and then recompiled the pve-qemu package as per previous instructions.
PPPS. seems that the VAProfiles also work on buster, not only trixie.
Code:

But if i install virglrenderer though apt, i won't get those codecs, even if i am on PVE9 and Debian 13, am i right? I only have a AMD S7150x2, I don't have AMD Ryzen CPU and I don't want to spend extra money in short term.Using these steps I was able to build qemu 10. Even though I have accelerated graphics in wayland on my VM i don't have access to the hardware codecs

If I am right, i am going to issue a bug to Debian community, do you know where should I raise the bug? Debian forum or Gitlab?
I think that the Debian package maintainer needs to pull in the latest release.But if i install virglrenderer though apt, i won't get those codecs, even if i am on PVE9 and Debian 13, am i right?

I would wait and see if this versions make it into unstable, then forky and then perhaps trixie-backports.
What's the line you're drawing in the sand tho? There's still a patch needed for QEMU, so you still need to compile thingies.
LE. I think all intel and amd gpus can do this right now, not sure about nvidia.
For certain intel integrated gpus you can even enable sr-iov so there's that.
here is the debian packagepage https://tracker.debian.org/pkg/virglrenderer

From i understand, you are using latest virglrender from Freedesktop (instead of Debian) + Debian directory. Right? Did you make any other change?I think that the Debian package maintainer needs to pull in the latest release.This being said there isn't a new release of virglrenderer either.It seems that a new release of virgilrenderer was cut yesterday - https://gitlab.freedesktop.org/virgl/virglrenderer/-/releases

Also, since which version of virglrender start to include those codecs?
By the way, what patch do I need for QEMU? Was that a patch included in QEMU but not compiled by Proxmox or?
What is your VM config?I think that the Debian package maintainer needs to pull in the latest release.This being said there isn't a new release of virglrenderer either.It seems that a new release of virgilrenderer was cut yesterday - https://gitlab.freedesktop.org/virgl/virglrenderer/-/releases

if you look at what wo56bytes wrote you'll see that after installing the latest version of virglrenderer you need to patch - step 6 of compiling qemu.
Here's my trixie vm - i think it's pretty standard. I am passing through the nic - as i'm using sr-iov for it.
