A Little Background
——————————————————————–

First, let me give a little background since this seems like an unnecessary use case. I had the idea of converting a physical Windows PC into a ProxMox VM (P2V) to allow me to better separate the PC resources for different tasks. Currently one of the main uses for the PC is to quickly test different things using VirtualBox. This could be testing new Linux distro releases, working through steps for a new application install tutorial or walking through the steps of an existing tutorial when an issue is reported by a viewer. I have a workflow that I like to use and I didn’t want to abandon VirtualBox and migrate the workflow to ProxMox. So, is it possible and if so, how well does it work?

01. Log into the Proxmox Web UI
02. Expand the node and select the target VM
03. Select Hardware from the sub-navigation menu
04. Double click the Processors entry ≫ Set the Type value to host
Note: this will passthrough all the functionality of the Proxmox host processor to the VM
05. Start the Proxmox VM
06. Log into the VM
07. Download VirtualBox and the Virtualbox Extension Pack
08. Install VirtualBox
09. Install the VirtualBox Extension Pack
10. Create or import a 64-bit VirtualBox VM
11. Start the new VirtualBox VM
12. Does is work?
