    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.

        I have two GPUs - an RX 550 hooked to the monitors and 580 for VMs. Until recently, once the VM shut down, the 580 was able to return to Linux and be used again via PRIME - no reset bug. It randomly stopped working and I’ve tried to debug it to fix the problem to little avail.

          I actually may have seen the same issue recently. Have you tried adding initcall_blacklist=simpledrm_platform_driver_init to your kernel launch params?

            I’ll have to try that. What I have tried so far is running a different kernel version and making sure my driver blacklists are correct (I found that the GPU shouldn’t ever connect to snd_hda_intel. It briefly eas again, but after fixing it, I still had the problem.).

              For me, I have intel integrated + amd discrete. When I tried to set DRI_PRIME to 0 it complained that 0 was invalid, when I set it to 2 it said it had to be less than the number of GPUs detected (2). After digging in I noticed my cards in /dev/dri/by-path were card1 card2 rather than 0 and 1 like everyone online said they should be. Searching for that I found a few threads like this one that mentioned simpledrm was enabled by default in 6.4.8, which apparently broke some kind of enumeration with amd GPUs. I don’t really understand why, but setting that param made my cards number correctly, and prime selection works again.

                Huh. My issue seems different, but I’ll still test that flag to see if it changes anything. My problem looks like the device doesn’t return to host after VM shutdown, possibly because of the reset bug (based on my observation of dmesg), which I hadn’t encountered after about a year of GPU passthrough VM usage.

                  Ahh, yeah if it’s specifically when coming back from a VM, that sounds different. Maybe the vfio_pci driver isn’t getting swapped back to the real one? I barely know how it works, I’m sure you’ve checked everything.

      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?

        I go to the host folder I want to transfer files from and run ‘’’python3 -m http.server’’’. Then (I can’t remove if I use ‘’’ip a’’’ to find the IP address of the host or if I used mDNS), I use the guest web browser to download files.

    virtmanager as frontend for qemu/kvm. I tried the commandline but it’s too annoying

        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 used KVM with virt-manager for 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.

    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 is a frontend for a bunch of virtualisation systems, but usually it’s configured for qemu+kvm+libvirt.

        Libvirt is a dedicated API to managing virtual machines. It’s probably most versatile when launching new VMs on it by using the libvirt XML definitions, but there’s an API you can use if you want more low level access, and optional command line tooling as well.

        Something like virt-install --name=lemmyvm --vcpus=1 --memory=2048 --cdrom=/tmp/debian-netinst.iso --disk size=50 --os-variant=debian12 should automatically install a Debian 12 VM (from a downloaded ISO) through the automated setup process. It’s been a while since I used that, though, so you may need an extra step or two to get the setup to autocomplete today. I think cloudinit is how you auto setup Linux distros these days?

        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)

    Qemu+Kvm with virt-manager is my boy nowadays. But I’m not a heavy user of Vms, just experimented with this to build some Flatpak. But plan on trying out other distributions, just for science. It wasn’t easy to figure out how to share a folder, and I could not get drag and drop or clipboard share to work. Still though, its faster than any other solution. I used VirtualBox in the past, which was easy to work with.

    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.

    I use libvirt to do all my kvm/qemu stuff on my server. Using cockpit-machines web UI as a frontend. On my workstation if I ever need a VM I usually turn to Gnome Boxes for simplicity
