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 21.10
quickemu --vm ubuntu-mate-21.10-.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
--------
- **macOS** Monterey, Big Sur, Catalina, Mojave & High Sierra
- **Windows** 8.1, 10 and 11 including TPM 2.0

flavours](https://ubuntu.com/download/flavours)**
- **Over 360 operating system editions are supported!**
- Full SPICE support including host/guest clipboard sharing
- VirtIO-webdavd file sharing for Linux and Windows guests
- VirtIO-9p file sharing for Linux and macOS guests
- [QEMU Guest Agent
support](https://wiki.qemu.org/Features/GuestAgent); provides access

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
```
Ubuntu Guest
------------
`quickget` will automatically download an Ubuntu release and create the
virtual machine configuration.
``` {.bash}
quickget ubuntu 20.04
quickemu --vm ubuntu-20.04.conf
```
- Complete the installation as normal.
- Post-install:
- Install the SPICE agent (`spice-vdagent`) to enable copy/paste
and USB redirection
- `sudo apt install spice-vdagent`
- Install the SPICE WebDAV agent (`spice-webdavd`) to enable file
sharing.
- `sudo apt install spice-webdavd`
### Ubuntu devel (daily-live) images
`quickget` can also download/refresh devel images via `zsync` for Ubuntu
developers and testers.
``` {.bash}
quickget ubuntu devel
quickemu --vm ubuntu-devel.conf
```
You can run `quickget ubuntu devel` to refresh your daily development
image as often as you like, it will even automatically switch to a new
series.

``` {.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`) to enable copy/paste
and USB redirection.
- Install the SPICE WebDAV agent (`spice-webdavd`) 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**
- On macOS Catalina, Big Sur & Monterey
- Select `Apple Inc. VirtIO Block Media` from the list and
click **Erase**.
- On macOS Mojave and High Sierra
- Select `QEMU HARDDISK Media` (\~103.08GB) from the list
and click **Erase**.
- Enter a `Name:` for the disk and 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
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 works on macOS High Sierra, Mojave and Catalina.
- **macOS Big Sur and Monterey have no audio at all**.
- 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**.
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.
### 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"
```
- `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`.
All the options
===============
Here are the usage instructions:
``` {.bash}
Usage
quickemu --vm ubuntu.conf
You can also pass optional parameters
--braille : Enable braille support. Requires SDL.
--delete-disk : Delete the disk image and EFI variables
--delete-vm : Delete the entire VM and it's configuration
--display : Select display backend. 'sdl' (default), 'gtk', 'none', or 'spice'
--fullscreen : Starts VM in full screen mode (Ctl+Alt+f to exit)
--ignore-msrs-always : Configure KVM to always ignore unhandled machine-specific registers
--screen <screen> : Use specified screen to determine the window size.
--shortcut : Create a desktop shortcut
--snapshot apply <tag> : Apply/restore a snapshot.
--snapshot create <tag> : Create a snapshot.
--snapshot delete <tag> : Delete a snapshot.
--snapshot info : Show disk/snapshot info.
--status-quo : Do not commit any changes to disk/snapshot.
--version : Print version
```
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-20.04-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.
