Hi, i dont know what i did wrong, but i cannot make any changes of VM from webui, i got below error: please guide me how to resolve this? i change 2 different client pc and different browser but not helping. is there anyway i can reinstall proxmox without impact the current VM? thank you.

not sure if it was just me, but after latest update i cannot change VM configuration anymore. making any configuration change in the webui will return in this error.

I am alderlake owner, and even with igpu passthrough to Linux, it still perform like 2fps which is not useable. one can consider about this using virgl. i got it working and the performance is about 2~3 times of virtio-gpu when benchmark under webgl, not super good but worth consider...

thanks a lot. this really helped me a lot! but the is a small mistake in your original post workaround that I hacked /usr/share/perl5/PVE/QemuServer.pm to use virtgl-vga-gl in place of vmware should be virtio-vga-gl my VM now running webgl benchmark is improved by about 2.5 times compared...

in my case, disable KSM sharing, disable swap, and No Cache for any disk helped.

igpu was possible when i was using i8400 few years ago. but after i upgraded to i12400 early this year, i never got it working, although it passthrough correctly and successfully with VM desktop showing on monitor, however the spped is at like 1fps.

did you enable in BIOS? did you blacklist the driver?

i am using the latest version but i still getting this error: kvm: -display sdl,gl=on: SDL display supported is not available in this binary stopping swtpm instance (pid 3960) due to QEMU startup error TASK ERROR: start failed: QEMU exited with code 1 kvm: -display,egl-headless,gl=core...

it seems recent intel igpu are having difficulty to passthrough. my previous rig using 8400 have it igpu passthrough perfectly. but my latest rig 12400 although had it passthrough to ubuntu and install driver, but i am suffering at 1fps, complete useless. i am afraid 11th gen may have similar...

it should looks something similar to this.

i tried this, although i have it passthrough correctly to ubuntu, and ubuntu recognized it and installed MESA intel driver, but the desktop environment is running at 2~3fps.... https://forum.proxmox.com/threads/12th-gen-alderlake-gpu-passthrough-fail-slow-2-3-fps.105484/

thank you, but i will wait a few more days as i just saw this commit https://git.proxmox.com/?p=pve-qemu.git;a=commit;h=13d3e10aa678c4ed6baa24256f1cfab052a66eb2 thank you so much!

appreciate if there is a guide, or even a compiled pve-qemu for download.

I had followed the previous iGPU passthrough guide to passthrough a 12th Gen AlderLake GPU UHD730 to a Ubuntu box, I had made the ubuntu recognized the hardware, and installed the latest nightly and stable mesa utility, and updated latest kernal to 5.16. although the driver all seems installed...

did you tried to reboot the host? i had similar issues few months ago and restarting the host fixed it. https://forum.proxmox.com/threads/not-recognize-boot-order.78975/

when trying to use 4 IDE devices, i get below error root@proxmox:~# qm start 105 && qm terminal 105 -iface serial0 kvm: -device ide-hd,bus=ide.0,unit=1,drive=drive-ide1,id=ide1: Can't create IDE unit 1, bus supports only 1 units Use of uninitialized value $tpmpid in concatenation (.) or string...

yeap, i am using i7z to monitor cpu frequency and temperature, and using acpi is significanly lower frequency and temperature yet performance is similar.

well, i tried pstate with powersave, at it still try to kick my CPU to highest frequency and making my CPU 10c higher than ACPI conservative, even though my VM is not doing anything extensive.

whatever hardware you end up, i strongly suggest you to have a look of this guide https://forum.proxmox.com/threads/fix-always-high-cpu-frequency-in-proxmox-host.84270/

I notice that, even if I set all my CPU governor to powersaving with default intel_pstate drive, still the CPU gets up to maximum frequency as soon as VM started even it is almost idle in VM. CPU report in host show CPU boost up to 4Ghz for all cores. CPU temperature reported at about 50c. So I...
