Creating a Windows 10 Virtual Machine Using the Virtual Machine Manager (virt-manager)

Before you get your hopes high, this post is not (yet?) a tutorial on creating a Windows 10 virtual machine using the Virtual Machine Manager (virt-manager) GUI. It should have been, though. I spent the better part of a week trying to configure and install a Windows 10 VM that delivers the performance that I’m used to.

As it turns out, it was a failure. Don’t get me wrong, I did manage to configure and run Windows using virt-manager and virsh. I even installed it multiple times, changing the configuration to what I hoped would improve performance. But whatever I tried, I never got even near the speed and snappiness that I achieve by following my tutorial using a start script.

New PC Build

Back in 2012 I built a PC around the Intel i7 3930K 6-core/12HT processor which I have been using ever since. While it’s still a strong PC, especially with the upgrades (GPU, SSD) I made, I’m starting to feel that editing photos isn’t as snappy as it used to be. I am also curious in how well the new generation of CPUs lend themselves to VGA passthrough. In short, I’m considering building a new PC. Continue reading “New PC Build”

Linux Virtual Gaming Machine

You may wonder what’s wrong with this fellow (meaning me, the author). Has he completely lost his mind when he proposes a Linux virtual gaming machine? Before you discredit the idea, let me explain. Continue reading “Linux Virtual Gaming Machine”

Installing a Linux Mint 19 (Ubuntu 18.04) VM with VGA Passthrough

Introduction

Installing a Linux Mint 19 VM (or Ubuntu 18.04) with VGA passthrough is surprisingly straightforward. This tutorial follows the Running Windows 10 on Linux using KVM with VGA Passthrough almost step-by-step. I will therefore focus on what’s different from the above tutorial.

While booting the Linux Mint 19 life installation media (ISO) as a VM was easy, the installation of Linux Mint invariably ended with the following error:

The ‘grub-efi-amd64-signed’ package failed to install target/

The following tutorial will describe the steps to overcome this problem (bug?). Continue reading “Installing a Linux Mint 19 (Ubuntu 18.04) VM with VGA Passthrough”

Windows 10 Virtual Machine Benchmarks

Benchmarking Performance of a Virtual Machine

I have run  a number of benchmarks to document the performance of Windows 10 running as a virtual machine on Linux, in the hope other PC users will dive into the fascinating world of virtualization.

Benchmarks are helpful in comparing one system with another, and one configuration with another. I use them for optimizing my Windows 10 performance and for making sure that updates/upgrades haven’t produced unwanted side effects. Continue reading “Windows 10 Virtual Machine Benchmarks”

Virtual Machines on UserBenchmark

For some years I have encouraged benchmarking of Windows virtual machines (VM), to help users fine-tune the configuration and to get a general idea of how efficient virtualisation with Xen or KVM actually is. My benchmarks – posted under the username “powerhouse” – and those of other users can be found on the Linux Mint forum under Post your Passmark results of your Windows VM and UserBenchmark – post your results. When reviewing some of my benchmarks on the UserBenchmark website, it occurred to me that the information on that website can be put to  practical use.

Developments in Virtualization

I haven’t had much time in recent months to follow up on what’s happening in the KVM or virtualization world. That much bigger was my surprise to find that things are moving on quickly. When I started out 6 years ago to virtualise Windows and run it on Xen using VGA passthrough, I thought I would be forever marked as a geek.

Today I’m looking at dozens if not hundreds of tutorials and websites dealing with VGA passthrough, and an ever increasing number of followers. It seems to me this technology or concept is gaining momentum, at least among Linux users.

IOMMU Groups – What You Need to Consider

Summary

In this post I present some of the challenges you might face with IOMMU and provide tools to identify and perhaps solve the issues. Your best friend is the pciutils package and the lspci command (see here for examples).

What is IOMMU and why do I need it?

In my tutorial on how to run Windows 10 on Linux using KVM with VGA Passthrough the first and most important hardware requirement is the support for IOMMU – VT-d in Intel jargon, AMD-v or SVM in AMD talk. But what does IOMMU support mean? Continue reading “IOMMU Groups – What You Need to Consider”

Running Windows 10 on Linux using KVM with VGA Passthrough

The Need

You want to use Linux as your main operating system, but still need Windows for certain applications unavailable under Linux. You need top notch (3D) graphics performance under Windows for computer games, photo or video editing, etc. And you do not want to dual-boot into Linux or Windows. In that case read on.

Many modern CPUs have built-in features that improve the performance of virtual machines (VM), up to the point where virtualised systems are indistinguishable from non-virtualised systems. This allows us to create virtual machines on a Linux host platform without compromising performance of the (Windows) guest system.

For some benchmarks of my current system, see Windows 10 Virtual Machine Benchmarks Continue reading “Running Windows 10 on Linux using KVM with VGA Passthrough”
