### Configure the libvirtd service

Uncomment `unix_sock_group = "libvirt"` and `unix_sock_rw_perms = "0770"` in `/etc/libvirt/libvirtd.conf`.

```bash
sudo sed -i 's/^#unix_sock_group = "libvirt"/unix_sock_group = "libvirt"/' /etc/libvirt/libvirtd.conf
sudo sed -i 's/^#unix_sock_rw_perms = "0770"/unix_sock_rw_perms = "0770"/' /etc/libvirt/libvirtd.conf
```

### Add user to libvirt group
