None, I use Docker for Linux, and Proton (Heroic) for Windows.
But if I had to pick a virtual machine: libvirt with virt-manager as a frontend, which uses KVM for virtualization.
From my other comment:
Then I created a Docker image with Linux, Gnome, and novnc so I can spin one up instantly with little resource overhead and control it from any web browser.
Maybe I should release my Dockerfile.

Its fair bcs vmware workstation does not support gpu passthrough libvirt with virt-manager is the only way
OpenShift Virtualization
Correct me I'd I'm wrong, but with docker you're limited to the filesyatems and the image of the OS you're installing. If you need to experiment with the pre-OS boot events, can that even be accomplished with docker? E.g., trying out different GRUB settings, setting up LUKS with dropbear etc. I think those things require a VM.
Can virt-manager boot windows boxes?
Absolutely, it's also made way easier with quickemu, allows you to spin up a properly configured Windows VM with pretty much no effort
GNOME Boxes because it doesn't require 5 academic degrees to set up and I'm a GNOME user.
I’m a GNOME user.
Gross
Grow up. People use different software to you. It's not the end of the world.
Besides, Gnome is great.
Real for me it was problematic it was barely customizable and tracker3 randomly broke most of my apps
Qemu/KVM and Virt Manager. I have three VMs that I pass my GPU to: a Hackintosh, a Windows 10, and and Windows 7.
I never found a way to share a Public folder with VirtManager though, I need to move files between host and guest. How would you go about it?
Install the quemu guest agent in the VM. For Linux and Windows you'll even be able to drag and drop.
I hope you air gap that Windows 7 VM
Do you have two GPUs or do you fully switch to the VM while passed through?
I used KVM with
virt-managerfor a long time. Even ran a gaming VM with GPU pass-through.Then I created a Docker image with Linux, Gnome, and novnc so I can spin one up instantly with little resource overhead and control it from any web browser.
control it from any whuAT!?
KVM
(VMware is proprietary software)
virtmanager as frontend for qemu/kvm. I tried the commandline but it's too annoying
KVM + Qemu + libvirt + virt-manager = ❤️
Usually VirtualBox. It's easy and free.
a rather odd choice given the alternatives
Besides VMWare it always seemed the easiest for me to quickly make a Windows VM or so. Everything else usually had more configuration steps. But that's been a while ago. There could very well have been easier tools available in the mean time. I never bothered to look.
I only ever used "permanent" virtualization once on my server. I think with Xen. But it didn't give me any benefits for my use case so I dropped it later on. Also probably at least ten years ago.
I agree ngl i prefer vmware more
Me three.
I use virt-manager, aka Virtual Machine Manager. Using this specifically because of the winapps for Linux repo has instructions on how to get Windows apps to run through the VM to be integrated in a Linux environment.
How "scriptable" is virt-manager?
My biggest issue with VirtualBox is that I have to install OSes as if I'm actually installing them. There aren't any images (at least that I'm aware of) that can run with a command, like deploying an EC2.
Virt-manager isn't super scriptable but the underlying libvirt can be controlled by virsh which is a shell interface to libvirt. You can use both at the same time, e.g. start and stop via virsh and access to gui container via virt-manager/virt-viewer.
Virtual manager isn't scriptable at all as it is just a GUI for libvirt. You are probably looking for qemu or virsh (libvirt)
might try that tbh am gonna run razer software or apps that dont work on linux at all and for games am gonna use my windows ssd
Virtmanger-kvm-qemu
I'm kinda lazy so when I need one, I just use Gnome Boxes and it's pretty easy to setup.
I use qemu, but with Quickemu 'cause I'm lazy lol.
Proxmox seem powerfull
It's a Type1, not Type2
https://en.wikipedia.org/wiki/Hypervisor#ClassificationI use Proxmox for the machine that I use to download all of the Linux ISOs I want. You know, with a VPN, through BitTorrent. Linux ISOs.
Proxmox isn't really its own hypervisor. It combines a few common projects to make a OS. It is pretty much KVM with corosync for clustering.
With that being said it is a solid platform. Just keep in mind it is just standard Linux virtualization and for single nodes you can get the exact same setup easily on any Linux system.
Virtmanager and qemu/kvm
Gnome boxes.
Based on QEMU+KVM so it's quite robust. It works pretty well, plus it has various little features working out of the box that in some other software is a pain in the arse to configure.
Sticks out a bit on my system due to still being GTK3, but there is a GTK4 prototype out that usually works well.
E: downvoting anybody who says Gnome Boxes because you use a different virtual machine frontend is laughably pathetic lmao. Some people in the Linux community are such losers lol
Does it matter what front end it uses if the underlying environment is QEMU+KVM. Upvote for tha above.
It doesn't work for all cases and it is annoying that you have to wait until creation to change CPU count.
Virt-Manager, even works remotely via SSH.
Virt manager for qemu. I use docker and distrobox for Linux distros
I recently managed to use my windows partition (for dual boot) as a disk for a qemu. I don't use it but really cool trick anyways. Tutorial here
Also it's not very healthy for windows since it is not designed for constant hardware changes. But idc all my apps are installed on D: so I can just reinstall it without thinking about it much
I tried doing tbe same thing as you on my separate windows ssd gives me a error on bootup and qemu/kvm won't let me boot from my vendor usb I tried only putting the isos and windows cannot find the ssd and hiren just gets a error
@Mwa qemu :blobfoxcomfycomputer:
So far I’ve been fine with some Oracle Virtualbox and some using the VM Manager that was in my distro or maybe I downloaded it. It’s just called Virtual Machine Manager made by Red Hat. Libvirt.
Between those I’ve been able to do everything I have needed.
Linux: qemu
OpenBSD: vmm, qemu when vmm isn't good enough
Virtualbox
Owned by Oracle. Stay away from Oracle.
It also taints the kernel with a useless module and doesn't really offer much in the way of features over plain old kvm qemu
Raw qemu at the command line for the one I use on a daily basis (not recommended for the average user). VirtualBox if I need to spin something up quickly but don't expect to need to keep it past the current testing cycle.
Virtualbox is slow and the licensing for guest addons is nasty. It is proprietary of course and if a person in a company uses it unlicensed they will send the company a massive invoice.
I only need it for the very occasional testing of open-source software on Windows, using the precanned VM images provided by Microsoft (last I checked, they had none for qemu, or I would be using that instead). And if you're using software commercially, you'd better be damned sure you understand the licensing before setting up. A company of any size will have lawyers vetting that anyway.
In other words, I don't disagree with you, but those issues don't matter for my use case.
Currently virt-manager on top of qemu/kvm on Debian 12. It was the easiest to get to emulate a TPM on my ancient hardware (9ish years old, but still powerful).
I'm learning enough about the backend that I'm hoping to get off the Redhat maintained software and only use the qemu cli, maybe write my own monitor with rust-vmm when I learn enough rust to do so.
VirtualBox (desktop for testing and development [Vagrant]), KVM: libvirt, Proxmox (production stuff).
Just be mindful of guest addons. (The are not foss)
Gnome Boxes 🥲 Because im avoiding to install anything to the kernel.
You're using qemu+kvm.
https://help.gnome.org/users/gnome-boxes/stable/supported-protocols.html.en
You should never install anything to the kernel if possible tbh.
You also could try virtual manager
It is all KVM so it is natively supported
I tried using virt-manager+kvm to try some stuff out the other day but I failed to set-up some crucial things. Probably me being incompetent.
Not like virtualization is a big part of my life anyway. I just wanted to try some other distros and such without rebooting.
If I were to get serious about virtualization I'd need to build a new PC with a second GPU. Then I could stop dual-booting and do everything with VMs. But it'd only be worth it to get serious about learning how to virtualize stuff if I were to do that.
You can single pass through but it feels more like your using one os but if that's the case wouldn't dual booting be better
xcp-ng. except now everything is just containers on atomic fedora because it seems to fit my laziness better and doesn't require updating multiple vm os's
I use LXD (or Incus) containers
I've been curious about those for a while, what are they about, are they somehow better than the usual Docker/Podman conatiners?
They run a full distro rather than the minimalist that Docker containers use. You can also use them to run gui apps but that needs a bit more work to configure. I run Google Chrome sandboxed this way.
VMware, Virtualbox for OSes that hate VMware, and Qemu for emulating OSes that only run on obscure platforms.
Replied to others with this but realized you won't get those notifications. I finally got around to releasing this, which is Debian in your browser via Docker: https://nowsci.com/webbian
