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...

Hi, i followed this guide, successfully added proxmox to monitor my host machine temperature. https://blog.csdn.net/xiaobo060/article/details/105930003 do you think this can be implemented to proxmox officially? otherwise i need to manually add it again each time proxmox updated the related...

I tried that with the MSI-Ulti_v3 but too bad it doesn't help much.

some update about poping/cracking sound on HDMI passthrough: i had tried to lower down the speed of the PCIE from mobo BIOS, limiting all the PCIE speed to Gen2, and this make a lot improvement for the HDMI cracking sound. although it is not perfect but it is more acceptable now.

you need to install in your CT apt install openssh-server configure your sshserver to allow access.

also i am experiencing choppy/cracking sounds in my GTX1660s passthrough during youtube playback. strangely KODI and Gaming is ok dont have crackling sound problem...

Hi, here my configuration 1. Intel i7100 with oboard VGA 630HD 2. Asus GTX1660s on PCIE 3. I have 2 VM, a Windows 10 with 1660s, and a Linux Problem: 1. If I did not plug in GTX1660s to the host, i can passthrough 630HD to any VM (either Windows or Linux) without issues, all worked perfectly...

update, i never consider to reboot Proxmox host due to i have 4 VM running on. so today i tried reboot it, and it is now back to normal booting correctly. i guess this can be close, just never thought that KVM needed such reboot.

if i get inside bios and select to boot from here, it will then boot correctly but i cannot change the boot sequence, i tried to make changes for the boot order, however the next restart it always go back to boot DVD, the EFI shell, them harddisk

it always goes to this screen.

I had been getting this strange problem since 2 days ago. i have a linux VM that i had been using for few months and it was ok, i restart it time to time and all was ok. however, two days ago, when i restart, it goes in to UEFI interactive shell. i tried to change the boot sequence (in webgui...
