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. Continue reading “Prime95 Benchmark: Linux Host versus Windows VM”
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!”
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.
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.
I already wrote about why I think Linux is the way to go, and why I consider Linux more secure than most commercial operating systems. But what if your favorite distribution gets hacked?
Exactly this happened a little more than a year ago, when the Linux Mint website – probably the most popular Linux distribution – got hacked. The hacker placed a backdoored version of the Linux Mint ISO onto the download page. The perpetrator was also successful in hacking into the forum and stealing all user data and passwords. The user data / passwords are still available for purchase on the dark net, anyone paying the requested amount can download it.
Today, a year later, the Linux Mint forum and community websites are down. In the meantime the site has come up – according to a admin note it was shutdown for maintenance. Continue reading “Linux Security Part 2”
Yesterday I wrote about Linux security and the need for monitoring hard drives for failure symptoms. As if this was an omen, today the following message popped up on my screen:
In my “Why Linux” post, I explained the advantages of Linux over commercial operating systems such as Microsoft Windows or Apple OS. In this post I like to point out some of the risks running Linux. The risks are by no means limited to Linux – you run the same or similar risks with all the other OS. So why bother reading this post? Continue reading “Linux Security”
