cpu

Hello. I'm trying to start a VM (Windows10 x64) with the following parameters args: -cpu 'kvm64,vendor=GenuineIntel' The VM doesn't start. But args: -cpu 'host,vendor=GenuineIntel' args: -cpu 'qemu64,vendor=GenuineIntel' It starts. In "Vendor" I see intel. But I need kvm64. When...

Hi everyone, I had a few questions. I went to SCALE (So-Cal Linux Expo) and met with Ampere Engineers and had a good conversation. After the conversation had me thinking about using ARM instead of our x86 based CPU's. I know unofficially there is ARM64 support but I wanted to know: 1) Has...

I read the docs, and I want to make sure I understand it. When I assign a single socket/single core to a vm, does that mean proxmox will reserve a whole core to just that vm, or does it mean that that vm can only use 1 core max and no more? I am trying to size my host for the preposed work...

Hallo zusammen, vielen Dank vorab an alle, die mir bei meinem Problem helfen können! Ich nutze einen AMD Ryzen 9 9950X 16-Core-Prozessor (1 Socket), der über 32 Threads verfügt. Diese werden von Proxmox korrekt als 32 CPUs erkannt. Allerdings sieht meine Windows-VM nur 16 Threads und nutzt bei...

Guten Mittag zusammen, ich habe mich viel mit den Einstellungen von VMs beschäftigt und auch verschiedene CPU Typen getestet. Am besten soll ja immer Host sein, das kann ich bestätigen. Nun frage ich mich, wenn ich auf meinem Intel NUC mit N97 eine Ubuntu VM mit CPU Typ Host erstelle und...

Hello, I have a very strange problem. I have two PVE 8.3.0 nodes with AMD Ryzen CPU's, 64 GB RAM, 1 TB NVMe with ZFS and 2x 2,5 GBit NIC's on each node. All VM's replicate from node1 to node2 every 15 minutes. Node1 is the primary node, node2 was just added. When I try to live migrate a VM...

I am asking the following question, because I want to correctly limit the CPU consumptions of my VMs. My dedicated server from a hosting provider has the following specification: - AMD Ryzen 7 7700 8x3.8 GHz In my understanding, this is a single-socket server with a big chip holding 8 physical...

Could anyone help with procesor choice for my mini homelab? Do I need version pro to have all virtualization or no pro version is sufficient? Regards, Piotr

Hello everyone! Is it possible to "merge" CPU threads in proxmox to improve perfomance for VMs, that can't use many threads? For example, i have Dell R430 with two CPUs - 64 x Intel(R) Xeon(R) CPU E5-2698 v3 @ 2.30GHz (2 Sockets), but the most important VM on this host has a license limitation...

Hi, I am facing one problem on our proxmox server. Shows "Vulnerability Reg file data sampling: Vulnerable: No microcode" Please advise to us how to mitigate this issue. Please note, we are using no-subscription repository. Regards, Bichitra

Is there any documentation out there on the multitude of vCPU's you can choose when configuring a virtual environment? I.E. which ones are best for curtain use cases etc. I would be interested to see as my company has decided to start hosting some of it Virtual Environments within Proxmox and it...

Hi all I have 3 servers HP Proliant G8, all have Promox 8.2.4 in a cluster.. One of them recently show this error in syslog: Sep 13 14:47:05 pve2 kernel: kvm_intel: kvm [1295]: vcpu7, guest rIP: 0xfffff8034f7e7fa3 Unhandled WRMSR(0x1d9) = 0x1 Sep 13 14:47:05 pve2 kernel: kvm_intel: kvm [1295]...

Hello everyone, I installed proxmox on my intel system with an Nvidia gpu. I configured the system, so the gpu could be used by one of my VMs. It worked just fine but I decided to upgrade to an AMD ryzen 7 5700x cpu instead of the intel i5 11400. The mainboard used to be a Gigabyte B560M DS3H...

Hi all! Inexperienced user here I recently bought this HP Elitedesk 800 G2 to get into VMs and Proxmox, and out of the box it worked like a charm. However, I recently purchased a used i7-6700 and installed it (and upgraded the power supply to compensate), and now once I attempt to boot Proxmox...

What happened Yesterday I rebooted proxmox (which had an uptime of months) and found that when I started up my handbrake lxc my CPU wouldnt go above 15W draw. I have updated the host system maybe twice in the last few months but never had any issue, its possible I never rebooted after those...

I have a Ryzen 5600x. Is there any CPU flags I can pass that improve performance ? I am currently passing through host model I am not particularly concerned with the security implication

Hallo zusammen, ich brauche neue Hardware, aber ich habe keine Ahnung, wie ich am besten etwas suchen soll, was zu meinen Kriterien passt. Kurz zur Vorgeschichte: Ich hatte für kurze Zeit ein QNAP-NAS, habe schnell gemerkt, dass ich damit an meine Grenzen stoße. Habe mir dann einen Mini...

Hi everybody I am observing a strange behavior on a freshly installed PVE 8.2.2 (Intel i5-7600K/4 cores, 64 GB RAM), which I have never noticed before. Two VMs are installed: macOS Sonoma (via luchina-gabriel/OSX-PROXMOX) and Windows 11. In both cases, the processor type is set to "Host" and...

Short version: Anyone changed CPU type on a Windows 11 VM and know how to get it to stop crashing? Long version: I set up a Windows 11 VM in VE 8.2.2 and didn't notice the CPU type was set to x86-64-v2 instead of host. It was set to single processor with 8 cores. Everything was running...
