nested virtualization

Hello I've been trying run a nested proxmox instance on my already running proxmox installation. Installation went as normal and everything seem right. But the VM of the nested proxmox will, always eventually kernel panic. This are some of the panics it gave me over the course of trying to...

Hi, It looks like what you can not use at the same time AMD Nested Virtualization and GPU passthrough. When you do so, you will get VM crash, and 'guest-panicked' icon in UI. All I have in logs: proxmox kernel: kvm_amd: kvm [2955]: vcpu0, guest rIP: 0xfffff80e8093b475 Unhandled...

Given that Proxmox can be installed inside a third party hypervisor (see Nested Virtualization - Proxmox VE ) how should I calculate the number of physical sockets in order to purchase the right subscription? Should I count all the physical sockets of the hypervisor (even if they server lots of...

Is it possible to live migrate VMs that require nested virtualization? I’m currently running a Proxmox cluster with AMD Ryzen 7 7840HS processors. For instance, I have Home Assistant installed on one of the VMs, which also hosts several Docker containers. Right now, I’ve set the CPU...

I'm currently configuring a nested virtualization server, using Proxmox as my main hypervisor and Windows Server as my nested server. On this nested Windows Server, I'm running Ubuntu 22.04 Server, which I will use to host Bitwarden. During the Ubuntu server installation, I was unable to connect...

Hello, I reed the forum in this post "Proxmox 8 Breaks Nested Virtualization", but didn`t see any conclusion/solution so far. Is there a fix yet? I upgraded a few days ago to PVE8.2.2 with the last recent kernel "6.8.4-2-pve" but still no luck. I wanted to allow a user to use docker but docker...

Hi zusammen, ich bin gerade dabei mich in Proxmox einzuarbeiten und habe Privat bereits den Umstieg von vmware vSphere vollzogen. Das meiste war selbsterklärend bzw. durch die gute Dokumentation recht schnell zu verstehen. Jedoch habe ich ein Problem mit Docker, gemäß der Dokumentation habe...

Hi All. I have recently updated to the latest version of Proxmox, after which it appears that nested virtualisation no longer works. I noticed this because after the update reboot, docker, which is hosted in a privileged CT, can no longer run any containers. What ive tried so far: Ive tried...

Hallo zusammen Das Forum läuft noch.... ich denke die Anzahl der Mitglieder wird in der nächsten Zeit deutlich zunehmen. So steht bei mir auch ein Wechsel an den Sesselfurzenden Verwaltungsräte von Broadcom sei dank. Ich werde wohl bald meine Zeit solchen Entscheidungsträger weiterverrechnen...

I've created a VMware ESXi guest in PVE and cloned it twice to create a 3-node ESXi cluster on a single PVE host system. (Intel Core i7-7700K [4 cores @ 4.20GHz] with 64 GB of RAM) I've added an Ubuntu "helper" VM to test network connectivity inside of PVE... The ESXi Host Client interface of...

I've created an ESXi 8 guest inside of PVE 8. And I have two questions: Is there a guest agent that's capable of running on the ESXi guest? Should the "QEMU Guest Agent" option be enabled in the VM's system tab? TIA, Eric Pretorious Reno, Nevada

I have been trying to get a nested VM working for a few days with little success. Host is Proxmox 8 Steps I've taken: Confirmed the following: # dmesg | grep -E "DMAR|IOMMU" [ 0.000000] ACPI: DMAR 0x0000000078EB1D98 000168 (v01 SUPERM SMCI--MB 00000001 INTL 20091013) [ 0.000000] ACPI...

I realize that this is niche, but here I am.] I want to teach some people how to use proxmox and for that a brand new proxmox instance would be ideal. It turns out that the easiest way to do that for me would be to run proxmox inside a VM inside my usual proxmox instance. However, proxmox...

Cheers Sirs, I'm trying to open Docker Desktop in a W11 virtual machine, but I'm getting this alert: This is the WSL --Version WSL --status When I'm trying to install Ubuntu this error Display: About Windows Features: Aboute PVE Its Enabled Nested Virt on PVE: I have already...

When I enable wsl2 through windows platform, win11 vm immediately starts to boot into advanced recovery console. Any advice? I run Windows 11 as vm inside of proxmox 8. I successfully set gpu passthrough, and I am able to run Nvidia GPU inside of Win11. I can run games, furmark etc. But when I...

Hi, Been debugging why my Windows 10 machine (VM) is so darn slow. Found this, and it solved the issue. So far so good - until I tried to run a VM in Hyper-V on that same Windows 10 guest. Turns out you need to use host and not any of the other CPU types. It was absolutely flying on...

We're currently deploying our testenvironements with terraform into our proxmox cluster. Until now we had a separate vagrant configuration to spin up vms on our laptops for local development. We are thinking now about ways to simplify our setup. One way would be to use terraform to deploy the...

I've read through dozens of similar posts, but none seem to relate to this specific issue, and it's a weird one. If I install Proxox 7.4VE as a guest VM under an existing VMware environment (on metal), the networking/DHCP/everything in VE works as expected. If I then install an Ubuntu guest VM...

I am trying to configure nested virtualisation but am getting errors. when I start a nested VM created by proxmox. this is the configuration of the PVE system root@wlsc-pxmh01:/etc/pve/qemu-server# cat 10037.conf agent: 1,fstrim_cloned_disks=1 args: -object...

Hi all I need to install VMWare Workstation 12 Pro on an instance of a Windows 10 or a Windows Server 2019 which are installed on a ProxMox instance. For the virtual version of Windows installation I have allowed the host type for the CPU, which will allow for the Host's CPU's Virtualization...
