meson build -Dsystem=true -Ddriver_qemu=enabled -Ddriver_interface=enabled -Ddriver_libvirtd=enabled -Ddriver_remote=enabled -Ddriver_network=enabled --prefix=/usr
ninja -C build install

Edit the qemu configuration:

# vim /etc/libvirt/qemu.conf
cgroup_device_acl = [
    "/dev/null", "/dev/full", "/dev/zero",
    "/dev/random", "/dev/urandom",
    "/dev/ptmx", "/dev/kvm", "/dev/udmabuf"
