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”
Problem: bad 2D performance in Windows VM versus Windows on bare metal
For the past few months I noticed sluggish 2D graphics in my Windows 10 VM, something that hadn’t happened before. Below are the Passmark 8 results and comparisons between different configurations/releases: Continue reading “Low 2D Graphics Benchmark with Windows 10 (1803) KVM VM”
I just upgraded my Linux Mint Mate 18.3 installation to Linux Mint Mate 19, using the mintupgrade utility. It required some manual fixes, but all in all it went smooth.
Below the first UserBenchmark using Linux Mint 19 with updated qemu/kvm packages:
UserBenchmarks: Game 60%, Desk 76%, Work 67%
CPU: Intel Core i7-3930K – 86.8%
GPU: Nvidia GTX 970 – 58.5%
SSD: Red Hat VirtIO 140GB – 72.1%
HDD: Red Hat VirtIO 2.5TB – 87.1%
HDD: Red Hat VirtIO 2TB – 51.7%
RAM: QEMU 1x16GB – 77.3%
MBD: QEMU Standard PC (Q35 + ICH9, 2009)

This is yet another benchmark of my Windows 10 VM. This time I used the free Mersenne Prime Search software Prime95 (mprime under Linux) available at www.mersenne.org. I wanted to see if there is a significant difference between running the benchmark on the Linux host, versus the Windows virtual machine.

Benchmarks help us compare the performance of different hardware configurations as well as drivers and operating systems. With regard to virtualization, benchmarks can be particularly useful in quantifying performance differences between an operating system running on a virtual machine versus the same OS running directly on the underlying hardware.

In my Running Windows 10 on Linux using KVM with VGA Passthrough tutorial I introduced different options for using the keyboard and mouse with the Linux host and the Windows VM. Running a virtualized Windows VM means running two separate systems – the Linux host and the Windows VM – both of which require input and output devices.

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.

Microsoft has done it again! During the last Windows 10 upgrade, it has overwritten the user configuration and enable “Fast Startup”. Why in the world is Microsoft messing around with user preferences?
To be sure, I always turn off Hibernation and Fast Startup, since both interfere with mounting Windows partitions under Linux. But that’s not the only reason I turn off that nuisance. Continue reading “Microsoft – stop messing with your users!”
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.

Most PC users will be familiar with Microsoft Windows, some with Apple OS X. But what about Linux?
Linux has become popular as a server OS, but couldn’t win any desktop battle, yet. One of the reasons for Linux’ failure in the desktop market is its fragmentation. There is no Linux operating system, but dozens of different (competing) distributions, as these different flavors of Linux are called. “You got lots of choices” would the Linux aficionado explain.
While the software landscape under Linux has greatly improved, Microsoft is still the king when it comes to commercial software. And the fact that the vast majority of desktops run Windows practically guarantees that hardware will be compatible with Windows, which is not always true for Linux.
So why on earth should a Microsoft Windows user bother with Linux? Continue reading “Why Linux”
