remove qemu libvirt user from lightdm login screen

After installing kvm on my enlightenment 5 system I had a login for qemu libvirt to choose in the login screen. To remove it I ran:

printf "[User]\nSystemAccount=true\n" | sudo tee /var/lib/AccountsService/users/libvirt-qemu
sudo systemctl restart accounts-daemon.service

On the next login the entry was gone.
