For Ubuntu, Arch and NixOS hosts, the ppa, AUR or https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/quickemu nix packaging will take care of the dependencies. For other host distributions or operating systems it will be necessary to install the above requirements or their equivalents.

These examples may save a little typing:

Install requirements on Debian hosts¶

This also applies to derivatives:

sudo apt-get install bash coreutils curl genisoimage grep jq mesa-utils ovmf pciutils procps python3 qemu sed socat spice-client-gtk swtpm-tools unzip usbutils util-linux xdg-user-dirs xrandr zsync 
    

Install requirements on Fedora hosts¶

sudo dnf install bash coreutils curl edk2-tools genisoimage grep jq mesa-demos pciutils procps python3 qemu sed socat spice-gtk-tools swtpm unzip usbutils util-linux uuidgen-runtime xdg-user-dirs xrandr zsync
    

Install requirements on Gentoo¶

Please note that you may have to use sys-firmware/edk2-ovmf instead of sys-firmware/edk2-ovmf-bin - depending on how your system is configured.

sudo emerge --ask --noreplace app-emulation/qemu \


 app-shells/bash \


 sys-apps/coreutils \


 net-misc/curl \


 sys-firmware/edk2-ovmf-bin \


 sys-apps/gawk \


 sys-apps/grep \


 x11-apps/mesa-progs \


 app-misc/jq \


 sys-apps/pciutils \


 sys-process/procps \


 app-cdr/cdrtools \


 sys-apps/usbutils \


 sys-apps/util-linux \


 sys-apps/sed \


 net-misc/socat \


 app-emulation/spice \


 app-crypt/swtpm \


 x11-misc/xdg-user-dirs \


 x11-apps/xrandr \

Alternative Frontends

Quickgui¶

While quickemu and quickget are designed for the terminal, a graphical user interface is also available:

•

Quickgui by Mark Johnson and Yannick Mauray.

To install Quickgui on Ubuntu:

sudo add-apt-repository ppa:yannick-mauray/quickgui
sudo apt update
sudo apt install quickgui
    

Many thanks to Luke Wesley-Holley and Philipp Kiemle for creating the Quickemu icons 🎨

Creating Linux guests 🐧¶

Ubuntu¶

quickget will automatically download an Ubuntu release and create the virtual machine configuration.

quickget ubuntu 22.04
quickemu --vm ubuntu-22.04.conf
    

•

Complete the installation as normal.

•

Post-install:

Ubuntu daily-live images¶

quickget can also download/refresh daily-live images via zsync for Ubuntu developers and testers.

quickget ubuntu daily-live
quickemu --vm ubuntu-daily-live.conf
    

You can run quickget ubuntu daily-live to refresh your daily development image as often as you like, it will even automatically switch to a new series.

Ubuntu Flavours¶

All the official Ubuntu flavours are supported, just replace ubuntu with your preferred flavour.

  --list-json                              : List everything in json format
    

Here are some typical uses

    # show an OS ISO download URL for {os} {release} [edition]


    quickget --url fedora 38 Silverblue


    # test if an OS ISO is available for {os} {release} [edition]


    quickget --check nixos unstable plasma5


    # open an OS distribution homepage in a browser


    quickget --open-homepage  ubuntu-mate


    # Only download image file into current directory, without creating VM


    quickget --download elementary 7.1
    

The --url, --check, and --download options are fully functional for all operating systems, including Windows and macOS.

Custom Linux guestsOr you can download a Linux image and manually create a VM configuration.

•

Download a .iso image of a Linux distribution

•

Create a VM configuration file; for example debian-bullseye.conf

guest_os="linux"
disk_img="debian-bullseye/disk.qcow2"
iso="debian-bullseye/firmware-11.0.0-amd64-DVD-1.iso"
    

•

Use quickemu to start the virtual machine:

quickemu --vm debian-bullseye.conf
    

•

Complete the installation as normal.

•

Post-install:

Supporting old Linux distros¶

If you want to run an old Linux , from 2016 or earlier, change the guest_os to linux_old. This will enable the vmware-svga graphics driver which is better supported on older distros.

Creating macOS Guests 🍏 Installing macOS in a VM can be a bit finicky, if you encounter problems, check the Discussions for solutions or ask for help there 🛟

quickget automatically downloads a macOS recovery image and creates a virtual machine configuration.

quickget macos big-sur
quickemu --vm macos-big-sur.conf
    

macOS mojave, catalina, big-sur, monterey, ventura and sonoma are supported.

•

Use cursor keys and enter key to select the macOS Base System

•

From macOS Utilities

•

From macOS Utilities

•

Complete the installation as you normally would.

•

Once you have finished installing macOS you will be presented with an the out-of-the-box first-start wizard to configure various options and set up your username and password

•

OPTIONAL: After you have concluded the out-of-the-box wizard, you may want to enable the TRIM feature that the computer industry created for SSD disks. This feature in our macOS installation will allow QuickEmu to compact (shrink) your macOS disk image whenever you delete files inside the Virtual Machine. Without this step your macOS disk image will only ever get larger and will not shrink even when you delete lots of data inside macOS.

sudo trimforce enable
    

You will be prompted to enter your account's password to gain the privilege needed. Once you've entered your password and pressed enter the command will request confirmation in the form of two questions that require you to type y (for a "yes" response) followed by enter to confirm.

If you press enter without first typing y the system will consider that a negative response as though you said "no":

IMPORTANT NOTICE: This tool force-enables TRIM for all relevant attached devices, even though such devices may not have been validated for data integrity while using TRIM. Use of this tool to enable TRIM may result in unintended data loss or data corruption. It should not be used in a commercial operating environment or with important data. Before using this tool, you should back up all of your data and regularly back up data while TRIM is enabled. This tool is provided on an "as is" basis. APPLE MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, REGARDING THIS TOOL OR ITS USE ALONE OR IN COMBINATION WITH YOUR DEVICES, SYSTEMS, OR SERVICES. BY USING THIS TOOL TO ENABLE TRIM, YOU AGREE THAT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, USE OF THE TOOL IS AT YOUR SOLE RISK AND THAT THE ENTIRE RISK AS TO SATISFACTORY QUALITY, PERFORMANCE, ACCURACY AND EFFORT IS WITH YOU.
Are you sure you with to proceed (y/N)?
    

And a second confirmation once you've confirmed the previous one:

Your system will immediately reboot when this is complete.
Is this OK (y/N)?
    

As the last message states, your system will automatically reboot as soon as the command completes.

The default macOS configuration looks like this:

guest_os="macos"
img="macos- big-sur/RecoveryImage.img"
disk_img="macos- big-sur/disk.qcow2"
macos_release=" big-sur"
    

•

guest_os="macos" instructs Quickemu to optimise for macOS.

•

macos_release=" big-sur" instructs Quickemu to optimise for a particular macOS release.

¶

Creating Windows guests 🪟 quickget can download Windows 10 and Windows 11 automatically and create an optimised virtual machine configuration. This configuration also includes the VirtIO drivers for Windows.

Windows 8.1 is also supported but doesn't feature any automated installation or driver optimisation.

quickget can also download https://www.microsoft.com/en-us/evalcenter/download-windows-10-enterprise Windows 10 LTSC and Windows Server https://www.microsoft.com/en-us/evalcenter/download-windows-server-2012-r2 2012-r2, https://www.microsoft.com/en-us/evalcenter/download-windows-server-2016 2016, https://www.microsoft.com/en-us/evalcenter/download-windows-server-2019 2019, and https://www.microsoft.com/en-us/evalcenter/download-windows-server-2022 2022. No automated installation is supported for these releases.

quickget windows 11
quickemu --vm windows-11.conf
    

•

Complete the installation as you normally would.

•

All relevant drivers and services should be installed automatically.

•

A local administrator user account is automatically created, with these credentials:
