Hi, I’m an old windows user who have played with linux* a few times, but never commited to it.

I want to dive deeper and I though about installing linux in a VM. Some basic questions:

  • Is that a good idea? / Anything I should take into account?
  • Is there any preferred VM manager for this? Windows comes with Hyper-V, but I remember reading about how Hyper-V is not ideal (I could be wrong).
  • Do different distributions work better or worse on VMs?
  • Are there any major differences when using linux in a VM compared to a bare metal installation?

And some not-so-basic ones:

  • Is there any [dis]advantage to “Linux VM on Windows” VS “Windows VM on Linux”?
  • If I start with “Linux VM on Windows”, would it be possible to swap them in the future? What I mean is:
    • Virtualize the Windows installation so it can be run as a VM.
    • Un-virtualize the Linux VM (with all its contents and configuration) and move it to bare metal.
    • Run Windows VM on linux.

Notes:

  • I did a quick search and, although I found multiple articles about the topic, the ones I’ve read just show one way to do it without comparing it to the alternatives.
  • I’m aware of WSL(2), but I would like to be able to decouple from Windows in the future.
  • EIDT: I tried dual booting in the past. The main problem is that I’m too lazy to reboot every time I want to try something in linux and I end up not using it.

Thanks!

If you’re interested in making a full jump to Linux at some point, then you’d probably be interested in dual-booting instead of using VM for Windows or Linux.

I think it’s far less invasive to setup a Linux VM that can be thrown away vs. setting up dual booting.

With Hyper-V or Virtualbox the OP can have a Linux distribution installed and booting very quickly without fear of disrupting his current Windows installation.

You’re right, but is it easy to convert a VM to a physical machine? I’ve never tried, so I’m genuinely asking.

I’ve always gone the other way, and ran my dual booting capable install in a virtual machine

I think if you can convert the virtualhard disk into raw files it should work the other way.

Generally yes, but I’ve been working with VMs on various platforms for a very long time, so I’m probably not the best to qualify on what easy is. How easy will depend on what software you are using.

I’ve done many physical to virtual, and the very rare virtual to physical. Both can have problems you may need to work through (almost always driver related).

It’s definitely possible to convert in both directions. I’ve never done it though. The technical hurdles made it unpalatable. My main method of moving back and forth was to keep my personal data on a separate disk from the OS disk. That way I could always take my data with me when I changed OSes or VMs.

I hope that with VMs I can have a smoother transition being able to work with both of them at the same time.

I should have added that… thanks for the suggestion.

What do you use Windows primarily for? If it’s not for online multiplayer gaming (which uses anti-cheat software), then you should do it the other way around, ie install Linux as your main OS and use Windows inside a VM. That way you will be sort of forced to use Linux and adjust, and you can always fire up your Windows VM if you need to.

The only program that I’m aware I need Windows for is Photoshop (I don’t know if Wine is an option or if that counts as "Windows).

So you’re probably right. The main reason I prefer to start with VMs is to try a few distributions before committing to one of them… and the laziness I get thinking about how to migrate my current Windows installation to a VM… or (even worse) reinstalling Windows from scratch :P.

I’m that way too. When I dual booted, I just let the default OS run. I find it better to use Linux on a VM. I’m on a mac now so I use VMs to run windows and Linux. I have a few flavors installed, but my default is Ubuntu.

I used VirtualBox to test Linux distributions at first. What I loved doing was install it, put it in full screen and use it one or two days the whole day using it for serious tasks and to mess around. Didn’t game on it of course because graphical capabilities in VMs are severely diminished. Thanks to this I found my true love being Debian, and I’ve been using it every day for 2 years after I’ve installed it outside of the VM.

I still do it but now I mess around in PCem with Windows 9x and pre-XP NT releases.

Do you know of any advantage of using VirtualBox over Hyper-V?

It depends on what you are trying to accomplish.

If you want a pretty desktop environment or you need all the bells and whistles of a specific Linux distribution (Debian, Fedora, Ubuntu, CentOS, etc.) then a virtualize environment is probably the way to go.

If you just want to get used to playing with Linux commands using bash and you only need about 80% of the full functionality of a pure Linux environment, then Windows offers the Subsystem for Linux which installs like an app you can run at anytime.

I personally use the subsystem for Linux on my Windows work laptop so I can quickly write Python scripts and test application configs for production servers. It’s quick and dirty and I can easily share files between Windows and Linux. It also has a small footprint on the computer as oppose to a VM.

Whatever you decide, have fun! Linux is awesome.

Is this a good idea?

Sure!

any preferred VM manager

I like Virtualbox.

  • Do different distributions work better or worse?

Depending on your specs, you may want to go lighter than you would on bare metal. For example, if you have 16 GB of RAM, you might want to only give your VM 4 GB of RAM so Windows can run on 12 GB, and then pick a lighter distro so it won’t be slow on 4 GB.

Any major differences?

Snapshots are way easier in a VM.

Advantage/disadvantage

Windows VM on linux is painfully slow and doesn’t have a license, so it’s much less good than linux VM on Windows IMO.

Would it be possible to swap?

Not as far as I’m aware, but smarter people than me have probably done it.

Windows vm on a Linux box is not painfully slow. It’s about the same as native, where did you get this idea?

You can license Windows in a VM, you can grab your Windows license from the UEFI system using a command:

sudo strings /sys/firmware/acpi/tables/MSDM

Good point regarding balancing hardware resources.

Good to know.

Thanks!

Short answer: go ahead and install whichever Linux distro you like on Hyper-V and go from there.

Longer answers:

Linux works fine on VMs. There aren’t really any caveats. Hyper-V should be fine. It’s been a while since I used it but I remember thinking it was OK. I preferred it to Virtualbox; I think the Virtualbox drivers made some stuff flaky on my machine, but YMMV. I ended up shelling out for VMWare which I’d used at work. Some distros offer cloud images that are tailored for running as VMs, but unless you’re running a cluster with a lot of VMs I don’t think there’s any advantage, any distro will work. There aren’t any significant differences running Linux on a VM from running it on a physical machine.

As to which OS to use for a host, the commonly understood strengths & weaknesses of each OS apply the same as they do in other domains. Windows has better desktop hardware support, Linux tends to be more power-user friendly, etc. It depends on your priorities which you choose. Maybe the biggest factor is that Windows has Hyper-V, whereas Linux has Xen, KVM, and qemu. Either platform can use Virtualbox or VMWare.

P2V and V2P are definitely things. Searching for them online will return tools that will do this. Linux should be rather straightforward to transfer even without a specialized tool, assuming you aren’t using a distro (or distro variant) that is specially built for VMs. dd should work like a charm. It should be possible to do invert the host and guest.

If that sounds like a whole lot of nothing it’s because that’s kind of the way it is with VMs. They just work.

I don’t know a distribution which work better on VM but for an old Windows user, I recommand Linux Mint. Close to windows GUI and really easy to use!

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
