1. Build QEMU via Toolchain/BuildQemu.sh
2. Install virt-viewer 8.0
   • On 23.04+ just do sudo apt-get install virt-viewer
   • For earlier versions you need to build it from source (see below).
3. export SERENITY_SPICE=1
4. Meta/serenity.sh run

Note: If you installed an old version from apt uninstall that first (sudo apt-get purge virt-viewer).

Install the build dependencies:

sudo apt-get install libvirt-glib-1.0 libvirt-dev spice-client-gtk-3.0 spice-client-glib-2.0 intltool

Fetch and extract the sources:

wget https://releases.pagure.org/virt-viewer/virt-viewer-8.0.tar.gz
tar -xvf virt-viewer-8.0.tar.gz

Configure and build:

cd ./virt-viewer-8.0
./configure --with-spice-gtk
make

sudo make install
