nested virtualization

Hi, I finally feel confident with my PVE setup. Backups are working fine with PBS over NFS, and all VMs are migrated from VMware ESXi since a few weeks back. In my previous setup with ESXi I ran a Windows 10 Pro VM with both Hyper-V and VMware Worksation nested. It worked great, and performance...

When I attempt to install a WSL distro, I get this error: WslRegisterDistribution failed with error: 0x80370102 Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS. I've enabled that and confirmed that nested virtualization is turned on...

I'm creating a virtualised pxc cluster on top of a proxmox installation configured with ceph storage. We are testing some automation with terraform and ansible. Ideally I would like configure ceph in this nested configuration, however that would be ceph of top of ceph. Will that work...

HI! I'm running Proxmox 7.2 on Intel i9-12900 and I can't get Nested Virtualization to work, whenever I try to install WSL2 on a guest VM, after required reboot I get stuck on black screen with Windows logo only (VM still works if I move it to a different node in my cluster with different CPU)...

Hi, I will have several critical VMs running as DDNS or OpenVPN or SSH bastion servers. They are not heavy workloads but are not allowed to stop. However, my company has only one physical server for budget reasons. So, I fancy that I could set up 3 nested Proxmox as guests, to only run above...

HI I installed HyperV on a VM running on my proxmox server. Now I have the issue, that as soon as I create an external virtual switch connected to my network interface, the network interface has no connectivity anymore. I can't reach any other devices in the same network anymore, which I could...

Hi, I've recently setup an Intel I5-12600 as a Proxmox host and I can't get Windows VMs with the hypervisor platform enabled to boot with the CPU set to host (boots just fine with the KVM64 CPU). The same VM boots just fine on a different Intel based Proxmox host and it boots just fine. Nested...

Good morning, guys! I've tried to install OpenStack on Proxmox, when I'm trying to start VM's in OpenStack I got error 2022-03-02T10:36:26.097821Z qemu-system-x86_64: warning: host doesn't support requested feature: MSR(48FH).vmx-exit-load-perf-global-ctrl [bit 12] 2022-03-02T10:36:26.097971Z...

Hi. For the purpose of creating a testing and development environment I need a virtual machine which hosts a Virtualbox installation. For this reason I enabled the nested virtualization following instructions at https://pve.proxmox.com/wiki/Nested_Virtualization on two different physical hosts...

Hi, I've a network problem on Proxmox configuration. I've installed Proxmox on a Cloud VPS (provider uses VmWare VE) with only one NIC and 3 public Ip addressess (same subnet and gateway). My goal is to assign one public Ip to the Host (Proxmox VE) and others to VMs I tried to configure a...

Hi, I am running a machine with freebsd operating system on proxmox. I am doing a virtualization again inside the FreeBSD operating system. I'm doing this with cbsd. When I create a virtual machine with cbsd and open it, the machine suddenly freezes. Then it gives an internal-error error. The...

Hello Team, I've been struggling with getting nested virtualization to work in one of my virtual machines. I get an error message when i attempt to start a virtual machine, using qemu-system-x86_64, which immediately fails. Here is the output generated from CLI for the nested VM...

Hi to get Ubuntu to work under Windows 10 (and avoid the "Please enable the virtual Machine Platform Windows feature and ensure virtualization in the BIOS"), I have to set the cpu type to host. But then guest if very slow. Which is expected according to Proxmox staff @Stefan_R ...

I am trying to setup proxmox to run windows vm that need to support nested virtualization and this is my first time using proxmox. I have ssd with windows 11 pre-installed. I pass through it via proxmox, set cpu type to Host, then started vm. It stuck on boot, causing cpu to reach 100%...

I have a Windows 10 VM that was working properly with hyper-v (amd nested virtualization enabled) in a AMD Threadripper 2970wx with CPU host,hidden=1, however after upgrade to 7.1 the machine goes to 100% CPU right after starting it and it crashes after sometime and I get below error message in...

TLTR: When you have an AMD Ryzen CPU and want to use any nested virtualization (nonfancy, just packer builds with Virtualbox) it will freeze about 5-10 seconds after starting the VM. To fix this issue, you need to upgrade your PVE kernel to 5.11. My setup: - Proxmox 6 latest patch version...

I'm using Proxmox 6.4 with 5.11 kernel for a Windows server virtual machine that runs a particular software that uses Virtualbox. The nested virtualization works fine, the problem is that after a while (about 40 min) I get a BSOD with the message "critical structure corruption". I installed all...

I would like to run ArkCase CE, which requires VirtualBox. I want to use ProxMox VE on the bare metal. I read a guide on how to convert a VirtualBox image to run on PMVE but the ArkCase seems to require a lot of extra steps. Can I install ProxMox-VE on bare metal, install CentOS as a guest OS...
