Virtual Gamming Machine

GPU Passthroung for Gaming or Train models inside a virtual machine with GPU passthrough (WIP)

This project intends to create, modify and run virtual machines with GPU passthrough.
Based on the tutorial: PCI_passthrough_via_OVMF

Attention

Early development state project (WIP).
Only Arch-Linux is supported currently. Ubuntu support is in development state.

TODO List

  • Allow use of non root user launch the virtual machine.
  • Add ubuntu support.
  • Enable dhcp on the bridge network.
  • Add looking glass host installation support.

Prepare the machine

Before you install/use this software:

  • Must have arch-linux installed
  • You need to enable the virtualization tecnologies on your bios. ("VT-d" or "AMD-Vi" or Virtualization technology)
  • You need to enable the internal graphics and disable gpu startup on your bios.
  • You need to enable IOMMU using kernel parameters (modifying your boot loader menu or it's configuration file).
    Set intel_iommu=on (for intel processors) or amd_iommu=on (for amd ones).
    You can add iommu=pt to prevent linux from touching devices that cant pass through.
    More information here Edit kernel parameters
  • You need to have two monitor or a monitor with 2 inputs (for the virtual machine and the host).
  • You need to isolate the GPUs you want to passthrough to prevent from the host OS using them. How to

Installation

pip3 install git+ssh://git@github.com/rodjjo/kvm-gpu-trainer.git --upgrade

Show help

vm-trainer --help
# or vm-trainer <command> --help

Install virtualization tools

vm-trainer depman-install-build-tools
vm-trainer depman-install-git
vm-trainer depman-install-qemu

Install scream

For more informations about scream click-here

vm-trainer depman-install-scream

Create the virtual machine

vm-trainer machine-create --name windows --cpus 4 --disk-size 200000 --memory 8192

Show host available gpus

vm-trainer show-gpus

Select the gpu for a machine

vm-trainer machine-set-gpus --name windows

Select the keyboard

You can press both CTRL keys to switch between the virtual machine and the host

vm-trainer machine-select-keyboard --name windows

Select the mouse

vm-trainer machine-select-mouse --name windows

Configure the network (internet)

You have to define the physical network adapter connected to the internet.

vm-trainer network-show-physical
# example of outputs:
# eth0
# enp6s0
vm-trainer settings-set-network-interface --name eth0

Run the virtual machine with an iso file to setup the operating system

vm-trainer machine-run-with-iso --name windows --iso location/to/my/original-windows10-disk.iso

Run the virtual machine without an iso attached to it

After you installed the operating system

vm-trainer machine-run --name windows

Network configuration

Currently, this project create a bridge network with the ip 192.168.66.1 (you can change this).
You need to configure the network in the virtual machine to use static ip configuration:

IP: 192.168.66.2  
Gateway: 192.168.66.1  
DNS: 8.8.8.8

DHCP (automatic ip configuration) support is at the TODO list.
