.SS Introduction
.PP
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:
.IP
.nf
\f[C]
quickget\ ubuntu\-mate\ 21.10
quickemu\ \-\-vm\ ubuntu\-mate\-21.10\-.conf
\f[]
.fi
.PP
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.
\f[B]Quickemu now also includes comprehensive support for macOS and
Windows\f[].

that attempts to automatically \f[I]\[lq]do the right thing\[rq]\f[],
rather than expose exhaustive configuration options.

.SS Desktop shortcuts
.PP
Desktop shortcuts can be created for a VM, the shortcuts are saved in
\f[C]~/.local/share/applications\f[].
Here is an example of how to create a shortcut.
.IP
.nf
\f[C]
quickemu\ \-\-vm\ ubuntu\-20.04\-desktop.conf\ \-\-shortcut
\f[]
.fi
.SS Screen and window size (Linux guests only)
.PP
\f[C]qemu\f[] will always default to the primary monitor to display the
VM's window.
.PP
Without the \f[C]\-\-screen\f[] option, \f[C]quickemu\f[] will look for
the size of the smallest monitor, and use a size that fits on said
monitor.
.PP
The \f[C]\-\-screen\f[] option forces \f[C]quickemu\f[] to use the size
of the given monitor to compute the size of the window.
\f[B]It won't use that monitor to display the VM's window if it's not
the primary monitor\f[].
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.
.PP
The \f[C]\-\-screen\f[] option is also useful with the
\f[C]\-\-fullscreen\f[] option, again because \f[C]qemu\f[] 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.
.PP
To know which screen to use, type:
.IP
.nf
\f[C]
xrandr\ \-\-listmonitors\ |\ grep\ \-v\ Monitors
\f[]
.fi
.PP
The command will output something like this:
.IP
.nf
\f[C]
\ 0:\ +*HDMI\-0\ 2560/597x1440/336+1920+0\ \ HDMI\-0
\ 1:\ +DVI\-D\-0\ 1920/527x1080/296+0+0\ \ DVI\-D\-0
\f[]
.fi
.PP
The first number is what needs to be passed to the \f[C]\-\-screen\f[]
option.
.PP
For example:
.IP
.nf
\f[C]
quickemu\ \-\-vm\ vm.conf\ \-\-screen\ 0
\f[]
.fi
.PP
The above uses the 2560x1440 screen to compute the size of the window,
which Quickemu sizes to 2048x1152.
Without the \f[C]\-\-screen\f[] option, Quickemu would have used the
1920x1080 monitor which results in a window size of 1664x936.
