Quickemu
Quickly create and run optimised Windows, macOS and Linux desktop virtual machines.
Made with 💝 for 
## Introduction
Quickly create and run highly optimised desktop virtual machines for
Linux, macOS and Windows; with just two commands. You decide what
operating system you want to run and Quickemu will figure out the best
way to do it for you. For example:
``` bash
quickget ubuntu-mate 22.04
quickemu --vm ubuntu-mate-22.04.conf
```
The original objective of the project was to enable quick testing of
Linux distributions where the virtual machine configurations can be
stored anywhere, such as external USB storage or your home directory,
and no elevated permissions are required to run the virtual machines.
**Quickemu now also includes comprehensive support for macOS and
Windows**.
## Features

### Installing Requirements
For Ubuntu, Arch and nixos systems the
[ppa](https://launchpad.net/~flexiondotorg/+archive/ubuntu/quickemu),
[AUR](https://aur.archlinux.org/packages/quickemu) or
[nix](https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/quickemu)
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

248](https://github.com/quickemu-project/quickemu/issues/248) for other
steps and changes that may enable running on MacOS)
brew install qemu bash coreutils grep jq python@3.10 cdrtools gnu-sed spice-gtk wget zsync
# Usage
## Graphical User Interfaces
While `quickemu` and `quickget` are designed for the terminal, a
graphical user interface is also available:
- **[Quickgui](https://github.com/quickgui/quickgui)** by [Mark
Johnson](https://github.com/marxjohnson) and [Yannick
Mauray](https://github.com/ymauray).
Many thanks to [Luke Wesley-Holley](https://github.com/Lukewh) and
[Philipp Kiemle](https://github.com/daPhipz) for creating the
**[Quickemu icons](https://github.com/Lukewh/quickemu-icons)** 🎨
### Quickgui for Ubuntu
``` bash
sudo add-apt-repository ppa:yannick-mauray/quickgui
sudo apt update
sudo apt install quickgui
```
# Install Quickemu

``` bash
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:
``` bash
quickemu --vm debian-bullseye.conf
```
- Complete the installation as normal.
- Post-install:
- Install the SPICE agent (`spice-vdagent`) in the guest to enable
copy/paste and USB redirection.
- Install the SPICE WebDAV agent (`spice-webdavd`) in the guest to
enable file sharing.
## macOS Guest
`quickget` automatically downloads a macOS recovery image and creates a
virtual machine configuration.
``` bash
quickget macos catalina
quickemu --vm macos-catalina.conf
```
macOS `high-sierra`, `mojave`, `catalina`, `big-sur` and `monterey` are
supported.
- Use cursor keys and enter key to select the **macOS Base System**
- From **macOS Utilities**
- Click **Disk Utility** and **Continue**
- Select `QEMU HARDDISK Media` (\~103.08GB) from the list and
click **Erase**.
- Enter a `Name:` for the disk
- If you are installing macOS Mojave or later (Catalina, Big
Sur, and Monterey), choose any of the APFS options as the
filesystem. MacOS Extended may not work.
- Click **Erase**.
- Click **Done**.
- Close Disk Utility
- From **macOS Utilities**
- Click **Reinstall macOS** and **Continue**
- Complete the installation as you normally would.
- On the first reboot use cursor keys and enter key to select
**macOS Installer**
- On the subsequent reboots use cursor keys and enter key to
select the disk you named
- 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.
- To enable TRIM, open the Terminal application and type the
following command followed by pressing
command on the hard disk when files are deleted:
``` bash
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
in the form of two questions that require you to type
response as though you said "no":
``` plain
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:
``` plain
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:
``` bash
guest_os="macos"
img="macos-catalina/RecoveryImage.img"
disk_img="macos-catalina/disk.qcow2"
macos_release="catalina"
```
- `guest_os="macos"` instructs Quickemu to optimise for macOS.
- `macos_release="catalina"` instructs Quickemu to optimise for a
particular macOS release.
- For example VirtIO Network and Memory Ballooning are available
in Big Sur and newer, but not previous releases.
- And VirtIO Block Media (disks) are supported/stable in Catalina
and newer.
### macOS compatibility
There are some considerations when running macOS via Quickemu.
- Supported macOS releases:
- High Sierra
- Mojave
- Catalina **(Recommended)**
- Big Sur
- Monterey
- `quickemu` will automatically download the required
[OpenCore](https://github.com/acidanthera/OpenCorePkg) bootloader
and OVMF firmware from [OSX-KVM](https://github.com/kholia/OSX-KVM).
- Optimised by default, but no GPU acceleration is available.
- Host CPU vendor is detected and guest CPU is optimised
accordingly.
- [VirtIO Block
Media](https://www.kraxel.org/blog/2019/06/macos-qemu-guest/) is
used for the system disk where supported.
- [VirtIO `usb-tablet`](http://philjordan.eu/osx-virt/) is used
for the mouse.
- VirtIO Network (`virtio-net`) is supported and enabled on macOS
Big Sur and newer but previous releases use `vmxnet3`.
- VirtIO Memory Ballooning is supported and enabled on macOS Big
Sur and newer but disabled for other support macOS releases.
- USB host and SPICE pass-through is:
- UHCI (USB 2.0) on macOS Catalina and earlier.
- XHCI (USB 3.0) on macOS Big Sur and newer.
- Display resolution can only be changed via macOS System Preferences.
- **Full Duplex audio requires [VoodooHDA
OC](https://github.com/chris1111/VoodooHDA-OC) or pass-through a USB
audio-device to the macOS guest VM**.
- NOTE! [Gatekeeper](https://disable-gatekeeper.github.io/) and
[System Integrity Protection
(SIP)](https://developer.apple.com/documentation/security/disabling_and_enabling_system_integrity_protection)
need to be disabled to install VoodooHDA OC
- File sharing between guest and host is available via
[virtio-9p](https://wiki.qemu.org/Documentation/9psetup) and [SPICE
webdavd](https://gitlab.gnome.org/GNOME/phodav/-/merge_requests/24).
- Copy/paste via SPICE agent is **not available on macOS**.
### macOS App Store
If you see *"Your device or computer could not be verified"* when you
try to login to the App Store, make sure that your wired ethernet device
is `en0`. Use `ifconfig` in a terminal to verify this.
If the wired ethernet device is not `en0`, then then go to *System
Preferences* -\> *Network*, delete all the network devices and apply the
changes. Next, open a terminal and run the following:
``` bash
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
```
Now reboot, and the App Store should work.
## Windows 8.1, 10 & 11 Guests
`quickget` can automatically download Windows 8.1, [Windows
10](https://www.microsoft.com/en-gb/software-download/windows10ISO) and
[Windows
11](https://www.microsoft.com/en-gb/software-download/windows11) along
with the [VirtIO drivers for
Windows](https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/)
and creates a virtual machine configuration.
``` bash
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 adminstrator user account is automatically created, with
these credentials:
- Username: `Quickemu`
- Password: `quickemu`
### Regional versions
By default `quickget` will download the *"English International"*
release, but you can optionally specify one of the supported languages:
For example:
``` bash
quickget windows 11 "Chinese (Traditional)"
```
The default Windows 11 configuration looks like this:
``` bash
guest_os="windows"
disk_img="windows-11/disk.qcow2"
iso="windows-11/Win11_EnglishInternational_x64.iso"
fixed_iso="windows-11/virtio-win.iso"
tpm="on"
secureboot="on"
```
- `guest_os="windows"` instructs `quickemu` to optimise for Windows.
- `fixed_iso=` specifies the ISO image that provides VirtIO drivers.
- `tpm="on"` instructs `quickemu` to create a software emulated TPM
device using `swtpm`.
# SPICE
The following features are available while using the SPICE protocol:
- Copy/paste between the guest and host
- Host file sharing to the guest
- USB device redirection
To use SPICE add `--display spice` to the Quickemu invocation, this
requires that the `spicy` client is installed, available from the
`spice-client-gtk` package in Debian/Ubuntu.
``` bash
quickemu --vm ubuntu-22.04.conf --display spice
```
To enable copy/paste with a Windows guest, install [SPICE Windows guest
tools](https://www.spice-space.org/download.html) in the guest VM.
## Headless
To start a VM with SPICE enabled, but no display attached use
`--display none`. This requires that the `spicy` client is installed,
available from the `spice-client-gtk` package in Debian/Ubuntu to
connect to the running VM
``` bash
quickemu --vm ubuntu-22.04.conf --display none
```
You can also use the `.ports` file in the VM directory to lookup what
SSH and SPICE ports the VM is connected to.
``` bash
cat ubuntu-22.04/ubuntu-22.04.ports
```
If, for example, the SSH port is set to 22220, and assuming your VM has
a started SSH service (details vary by OS), you can typically SSH into
it from the host as follows:
``` bash
ssh -p 22220 your_vm_user@localhost
```
# Accessibility
Qemu provides support for using BrlAPI to display braille output on a
real or fake device.
``` bash
quickemu --vm ubuntu-22.04.conf --braille --display sdl
```
# BIOS and EFI
Since Quickemu 2.1.0 `efi` is the default boot option. If you want to
override this behaviour then add the following line to you VM
configuration to enable legacy BIOS.
- `boot="legacy"` - Enable Legacy BIOS boot
# Tuning CPU cores, RAM & disks
By default, Quickemu will calculate the number of CPUs cores and RAM to
allocate to a VM based on the specifications of your host computer. You
can override this default behaviour and tune the VM configuration to
your liking.
Add additional lines to your virtual machine configuration:
- `cpu_cores="4"` - Specify the number of CPU cores allocated to the
VM
- `ram="4G"` - Specify the amount of RAM to allocate to the VM
- `disk_size="16G"` - Specify the size of the virtual disk allocated
to the VM
## Disk preallocation
Preallocation mode (allowed values: `off` (default), `metadata`,
`falloc`, `full`). An image with preallocated metadata is initially
larger but can improve performance when the image needs to grow.
Specify what disk preallocation should be used, if any, when creating
the system disk image by adding a line like this to your VM
configuration.
- `preallocation="metadata"`
## CD-ROM disks
If you want to expose an ISO image from the host to guest add the
following line to the VM configuration:
- `fixed_iso="/path/to/image.iso"`
## Floppy disks
If you're like [Alan Pope](https://popey.com) you'll probably want to
mount a floppy disk image in the guest. To do so add the following line
to the VM configuration:
- `floppy="/path/to/floppy.img"`
# File Sharing
All File Sharing options will only expose `~/Public` (or localised
variations) for the current user to the guest VMs.
## Samba 🐧 🍏 🪟
If `smbd` is available on the host, Quickemu will automatically enable
the built-in QEMU support for exposing a Samba share from the host to
the guest.
You can install the minimal Samba components on Ubuntu using:
``` bash
sudo apt install --no-install-recommends samba
```
If everything is set up correctly, the `smbd` address will be printed
when the virtual machine is started. For example:
- smbd: On guest: smb://10.0.2.4/qemu
If using a Windows guest, right-click on "This PC", click "Add a network
location", and paste this address, removing `smb:` and replacing forward
slashes with backslashes (in this example `\\10.0.2.4\qemu`).
## SPICE WebDAV 🐧 🪟
- TBD
## VirtIO-9P 🐧 🍏
- TBD
# Network port forwarding
Add an additional line to your virtual machine configuration. For
example:
- `port_forwards=("8123:8123" "8888:80")`
In the example above:
- Port 8123 on the host is forwarded to port 8123 on the guest.
- Port 8888 on the host is forwarded to port 80 on the guest.
# Disable networking
To completely disable all network interfaces in a guest VM add this
additional line to your virtual machine configuration:
- `network="none"`
# Restricted networking
You can isolate the guest from the host (and broader network) using the
restrict option, which will restrict networking to just the guest and
any virtual devices.
This can be used to prevent software running inside the guest from
phoning home while still providing a network inside the guest. Add this
additional line to your virtual machine configuration:
- `network="restrict"`
# Bridged networking
Connect your virtual machine to a preconfigured network bridge. Add an
additional line to your virtual machine configuration:
- `network="br0"`
If you want to have a persistent MAC address for your bridged network
interface in the guest VM you can add `macaddr` to the virtual machine
configuration. QEMU requires that the MAC address is in the range:
**52:54:00:AB:00:00 - 52:54:00:AB:FF:FF**
So you can generate your own MAC addresses with:
- `macaddr="52:54:00:AB:51:AE"`
# USB redirection
Quickemu supports USB redirection via SPICE pass-through and host
pass-through.
## SPICE redirection (recommended)
Using SPICE for USB pass-through is easiest as it doesn't require any
elevated permission, start Quickemu with `--display spice` and then
select `Input` -\> `Select USB Device for redirection` from the menu to
choose which device(s) you want to attach to the guest.
## Host redirection **NOT Recommended**
**USB host redirection is not recommended**, it is provided purely for
backwards compatibility to older versions of Quickemu. Using SPICE is
preferred, see above.
Add an additional line to your virtual machine configuration. For
example:
- `usb_devices=("046d:082d" "046d:085e")`
In the example above:
- The USB device with vendor_id 046d and product_id 082d will be
exposed to the guest.
- The USB device with vendor_id 046d and product_id 085e will be
exposed to the guest.
If the USB devices are not writable, `quickemu` will display the
appropriate commands to modify the USB device(s) access permissions,
like this:
- USB: Host pass-through requested:
- Sennheiser Communications EPOS GTW 270 on bus 001 device 005 needs permission changes:
sudo chown -v root:user /dev/bus/usb/001/005
ERROR! USB permission changes are required 👆
# TPM
Since Quickemu 2.2.0 a software emulated TPM device can be added to
guest virtual machines. Just add `tpm="on"` to your VM configuration.
`quickget` will automatically add this line to Windows 11 virtual
machines.
# All the options

```
## Desktop shortcuts
Desktop shortcuts can be created for a VM, the shortcuts are saved in
`~/.local/share/applications`. Here is an example of how to create a
shortcut.
``` bash
quickemu --vm ubuntu-22.04-desktop.conf --shortcut
```
## Screen and window size (Linux guests only)
`qemu` will always default to the primary monitor to display the VM's
window.
Without the `--screen` option, `quickemu` will look for the size of the
smallest monitor, and use a size that fits on said monitor.
The `--screen` option forces `quickemu` to use the size of the given
monitor to compute the size of the window. **It won't use that monitor
to display the VM's window if it's not the primary monitor**. This is
useful if the primary monitor if not the smallest one, and if the VM's
window doesn't need to be moved around.
The `--screen` option is also useful with the `--fullscreen` option,
again because `qemu` will always use the primary monitor. In order for
the fullscreen mode to work properly, the resolution of the VM's window
must match the resolution of the screen.
To know which screen to use, type:
``` bash
xrandr --listmonitors | grep -v Monitors
```
The command will output something like this:
``` bash
0: +*HDMI-0 2560/597x1440/336+1920+0 HDMI-0
1: +DVI-D-0 1920/527x1080/296+0+0 DVI-D-0
```
The first number is what needs to be passed to the `--screen` option.
For example:
``` bash
quickemu --vm vm.conf --screen 0
```
The above uses the 2560x1440 screen to compute the size of the window,
which Quickemu sizes to 2048x1152. Without the `--screen` option,
Quickemu would have used the 1920x1080 monitor which results in a window
size of 1664x936.
