Lvm enabled but VM reports error

[frankz]

Hello everyone, I installed a ubuntu VM, Plexmediaserver installed, but it does not start because it asks to enable KVM support, which is enabled.



1. The system's CPU supports virtualization.


2. Virtualization is enabled in the system BIOS.


3. The KVM kernel modules are loaded.

Is Proxmox VE nested within another hypervisor or running on bare metal?
Does the message to enable KVM occur on the host (Proxmox VE) or within the Ubuntu virtual machine?
Could you post the output of:

• pveversion -v
• lsmod | grep kvm
• journalctl -b | grep kvm

Hello, no, the error was reported directly by the VM, proxmox is a node that is part of a 3-node cluster.

Also if it can come in handy, I tried to install PLEX on a VM by following this guide.

Oh the guide sets up Plex in a virtual machine inside Ubuntu, so you need to set up nested virtualisation on your Proxmox VE host(s). We have a guide for this here: https://pve.proxmox.com/wiki/Nested_Virtualization
