...have KVM configured. @promo2100 @fiona I maybe found a "stable" workaround. Currently everything is running fine since ~15h. I have set cpuaffinity on all my QEMU-Machines. Every machine now only has P-Cores (0-13) or E-Cores (14-20) assigned (on 13th Gen Intel(R) Core(TM) i9-13900H). So...

Maybe this? Add a newly named Storage backend to only nodes 1 & 2, then add a disk (dummy) to that VM from that storage - migration will then be unsuccessful to other nodes that do not have that Storage backend.

Need to cover: - HA: it should not jump to an unlicensed host. What you shared should be good enough. - Manual operator mistake: Would require a mandatory VM to host affinity.

the linked bug report is about allowing affinity to be set by non-root users, if that is your issue, then yes.

...with all the changes to the AMD P-State Driver? Sadly, I don't know how to get to the bottom of the problem. Edit: Manually pinning the CPU Affinity of the 8 cores/16 threads of the VM to CCD0 (0-7,16-23) in 6.14 brings back the performance of 6.11 - at least in X-Plane (61 fps). However, in...

Hello, everyone, I'm integrating the PVE with one application using the API, however, when I try to define an affinity on the VM, the API returns error 500 with the message "only root can set 'affinity' config". Is there anything I can do to solve this issue? API Endpoint used: Create...

...noisy neighbor problems ... There are services which have a benefit to being on the same hardware .... Not all components have the same affinity factors... Setting an affinity within an HA group to bias slightly to server A vs server B will often result in all of the services of that...

Welcome to the Proxmox forum, Walder! As far as I know, there are no global configurations to limit either the physical core affinity and/or number of physical cores usable by an operating system type of VM guests. But one option is that you can set the physical core affinity [0] for each...

Werd ich mal versuchen. Hatte das gleiche mit einem i9 mit 32 Kernen aber auch., Aber werde es versuchen.

...also von einen Quad-Core-Xeon 8 Kerne der VM zugewiesen? Dann muss ja Windows abgehen... Lass mal die Cores auf 4 und stelle zurück auf nur einen Socket. Ich würde noch CPU-Affinity auf "0-3" einstellen. Dann hat die VM auf jeden Fall die "richtigen" Cores und die 4 HT-Cores bleiben für den Host.

...allocate these loads on different physical cores? edit: Well, I tested this myself. Doing a stress test inside a VM and changing the core affinity, while monitoring the core CPU usage on the host. Sometimes it does put the load on the "correct" physical core, but sometimes it doesn't. So I...

Yes but there is also the affinity setting. The virtual VM cores are scheduled by the Linux kernel scheduler. I cannot tell you how that works in any detail, but you investigate the Linux scheduler implementations on your own. Proxmox leaves this to the Linux kernel and QEMU/KVM...

...the memory comes from one NUMA domain and the other half comes from the other (with two virtual and physical sockets). You can set specific affinity for each virtual core (with 1 thread per core) if you want. See affinity in the manual...

Damn I really showed my age. Maybe my proxmox obsession is all some kind of midlife crisis? …then again always been tinkering with computers it etc :D

...unnecessary if what your are doing is not public. Damn you've been using windows since 3.11, I am much younger than that lol, first I used was XP and that was kinda old at that point with Windows 7 being out :). Explains the GUI affinity lol. Look forward to seeing what you get up to...

...> 5) Add a CPU core pinning UI facility with configuration via UI for hugepages too You can already do CPU Core pinning in the PVE GUI, as well as commandline scripting. Hardware / Processors / CPU Affinity https://github.com/kneutron/ansitest/blob/master/proxmox/proxmox-vm-assign-cpu-cores.sh

...issue is that "root only" settings are really limited to the root user (a token for that user might have restricted privileges after all). and when crossing the cluster boundary we need to re-check privileges. maybe it's time to expose affinity using some privilege? could you file a bug for that?

...PVE Nodes really comfortable. Today I encountered in issue in migrating a VM across two nodes. The error is apperently due to the CPU affinity setting on the source VM. The Datacenter Manager tries to set this on the target VM too, as I would expect it. However it fails with the error...
