    Enabled GPU passthrough of Intel HD 610 with GVT-g in Proxmox 8

    I was able to enable GPU passthrough for my Intel HD 610 (Pentium G4560) and Gigabyte h110m-ds2 motherboard fairly easily. Jellyfin h/w transcode in privileged LXC and video playback/discord stream in Win 11 was successful. However, I would really love a full passthrough instead of GVT-g which...

    I have an Ubuntu Server VM installed and configured. I have also set up that the iGPU on the host is passed through with iGVT-G. However, with this PCI passthrough, the output to console in PVE web UI is stopped when the iGPU is detected by the guest OS (after GRUB, but boots successfully, able...

    How can I change the addr of gvt-g mdev?

    Some opengl function of i915 must work on a device with addr 0000:00:02.0(a intel bug or opengl ? very annoying:mad:) In proxmox 7.0 the mdev is at 0000:00:10.0,and there is no way to change it via web or conf file.Is there some args like display=on in libvirt?

    [SOLVED] Intel GVT-g: can't assign more than one 5_4 mdev

    Hi, I've been stuck on this for almost an entire day now... The documentation in regards to GVT-g isn't that abundant. I expected to be able to use at least two i915-GVTg_V5_4 vGPUs. Instead, I'm only able to use 1 V5_4 or 2 V5_8. The resulting performance in my two VMs is thus absolutely...

    Mediated Intel iGPU (GVT-g) stopped working after kernel upgrade

    Hi, It seems that Mediated Intel iGPU (GVT-g) stopped working after the latest 5.4.55-1-pve kernel upgrade. It used to work in the past on the same system (Nothing other than the kernel upgrade has happened on the system since). I do see now a stack trace in the "dmesg" log where you can see...

    Hi, I have a Intel Pentium N4200 (HD Graphics 505) PC where I'm running Proxmox. I'm trying to use the Mediated GPU feature (i915-GVTg) on my machine. I tested with Linux and Windows and in both cases I get the following message in the Host (Proxmox): ... [ 144.757656] i915 0000:00:02.0...

    Linux kernel 5.1?

    Hi, Coffee-Lake GPUs need at least Linux 5.1 for KVMGT support (e.g. Intel Corporation UHD Graphics 610). Are there any plans for Linux 5.1, yet? Thanx for any hint! :)
