2. **Enable PCI Passthrough:**
```bash
salt '*' qcow2.modify_hardware_config vm_name='sensor1' pci='0000:00:1f.2' start=True
salt '*' qcow2.modify_hardware_config vm_name='sensor1' pci='0000:c7:00.0' pci='0000:c4:00.0' start=True
```
This configures PCI passthrough and starts the VM
3. **Complete Hardware Configuration:**
```bash
salt '*' qcow2.modify_hardware_config vm_name='sensor1' cpu=8 memory=16384 pci='0000:00:1f.2' start=True
salt '*' qcow2.modify_hardware_config vm_name='sensor1' cpu=8 memory=16384 pci='0000:c7:00.0' start=True
