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.

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”

Why run Windows on Linux?

I’ve written several tutorials on “how to make dual-boot obsolete using VGA passthrough“, yet one may ask why run Windows on Linux? Most PC or laptop come pre-installed with Windows, in fact its rare to see computers pre-installed with Linux. So why not just leave Windows and install Linux in a virtual machine (VM), for example using Oracle VirtualBox?

Installing Linux in a VirtualBox VM is definitely a lot easier than following my tutorials on VGA passthrough. Not only that, most computer users who want or need to use both Windows and Linux will find that this simple solution is all they need.

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.

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”
