cpu

Curious: has anyone done an analysis of what the memory and processors utilization differentials are between a virtual machine and an LXC container? I think it would be interesting to see how much more RAM a large and small virtual machine may use compared to both a large and small a container...

Hi, I've noticed that the CPU performance of the VMs is well below what it should be. I have a newer one that has a CPU with less performance than this newer one, and the VM on geekbench delivers what it should deliver. A VPS on the newer one has less performance than the previous generation...

Hello, I have Proxmox VE 7.0 running on PC with AMD Threadripper 2920X (12C/24T). SMT (or Hyperthreading) is enabled. CPU has two NUMA nodes. I have two VMs: 1. WIndows 10 VM for gaming and work. 2. Linux VM that is hosting game, web and mail servers. Both VMs have high CPU utilization. Windows...

Hello, I'm trying to get a reading of my cpu temperature but nothing seems to work really in Proxmox. My hardware is as follows: - Ryzen 9 5950X - Gigabyte Auorus B550M Pro-p I have updated everything to the newest state with: apt update apt dist-upgrade apt autoremove Then i tried to get a...

I'm very new to Proxmox and Hypervisors in general. VMs install and run with no issues when the CPU type is set to Default KVM64, but setting to Host (or if I specify the processor type as Westmere, which it is, it errors the same way) will result in an error when installing OS after the reboot...

Hi, Ich habe hier noch ein altes Board mit einem Intel J4005 rumliegen und habe als Testsystem Proxmox draufgehauen. Proxmox selbst läuft auf einer NVMe SSD, zudem habe ich eine weitere SATA SSD und eine HDD als ZFS Single Disk hinzugefügt. Bei einem Test via Samba ist mir aufgefallen, dass...

There is one ms windows vm which behaves quite peculiar. Changing the CPU away from anything kvm64 (> host) results in an inability to boot. Even a reboot into safe mode use msconfig does not work as per usual. Despite having configured a windows10 .iso to boot from the 'press any key to boot...

Hello, I have promox, and I have the following processor: Intel Xeon D-1521, But Promox only detects that I only have 2 threads when I have 8. So I would like to know how to modify this, I have already looked a little on the forum, but found nothing :). I attach you a screenshot of Iscpu Please...

Hello, I have Proxmox VE 6.3-3 running on a Dell Server with an Intel® Xeon® Processor E5-2680 v3 (2x 12 core). Hyperthreading is enabled, so a maximum of 48 cores are available. What is the correct configuration to allow a VM to use all 48 cores? I tried setting Sockets to 2 and Cores to 24...

Hallo Proxmox Community! Ich habe ein riesen Problem. Mein Proxmox system ist sooo langsam... Ich habe dann Mal in byobu zufällig gesehen dass meine CPU bei 0,5GHz (544MHz) läuft. Egal was auf den VMs bzw auf dem Proxmox passiert selbst wenn er 100% Auslastung hat es bleibt bei 544MHz... Was...

Hi, I have only single VM, running with ParrotOs, when i update my system my vm and node freeze like picture: I have Lenovo ThinkCentre M700 with 4 Ram and 150 SSD. Thank you.

I got a new server and found some issues during loading and adding new VMs. At first it froze, but after Proxmox upgrading it restarts automatically. It prints 'Start all VMs and Containers' in the tasks. Provider tested its hardware and didn't found any problems. But I can see mce: [Hardware...

We are looking to enable hotplug for the CPU for KVM guests. I've seen that it's only possible with vCPU and not Sockets nor Cores. Assuming the host has 32 cores, would it be best practice to set Sockets: 2 Cores: 16 and set the vCPU to 6 or according to the guest CPU need. If I understand...

Hello, I was under the impression that the reported CPU usage in the webui for LXC is in % but I'm having doubts. According to this picture: is the container using 10% cpu or it has a load of 10 (just like top would report) Thanks

Hi! Some exotic problems arriverd :) Recently i move lxc container from host with pve 4.2-18 to host with pve 6.0-11. Just created new container, then move .raw file from old host to new. I moved 4 containers, 3 works fine, but 1 displays 100% cpu usage by host utils like top or htop. Before...

Hello. I already installed macOS using Proxmox on my rig. My CPU is 3rd Threadripper 3960x. I see little lags when I am using macOS and try to find reason. I found here that is not recommended use maximum cores of your CPU for VM (that was my case. I had set 3x16 cores) and now beginning my...

Hey Everyone, Back from ESXi-land with another valuable question, well two in fact. The question in the title is about measuring CPU resource usage in more detail, for example in Proxmox I love that there is an oi-delay counter. Questions: How would one go about measuring something like...

Hello, I`m very confused with NUMA, as I read from docs you have a NUMA capable host if you have multiple CPUs (sockets). However I have installed Proxmox 6.1 (latest) on a AMD EPYC 16 core CPU, and the command to check available numa returns: available: 4 nodes (0-3) node 0 cpus: 0 1 2 3 16...

Hallo zusammen, ich habe vor ein paar Tagen Proxmox installiert und bin fleißig am bastel. Ich habe nun 2 VM's (iobroker und OpenMediaVault) und 2 Container (Grafana und InfluxDB) erstellt und mir fällt auf, dass die CPU Auslastung sehr hoch zu sein scheint. Die einzelnen Container / VM's haben...

I'm having a problem that has been reported by other Debian and Ubuntu users that udisksd is using lots of CPU. Right now I'm investigating workarounds rather than solutions so my question is: Is this service essential to Proxmox? What happens if I stop and disable it?
