⁠4.13. Example: Creating a Virtual Machine NIC using Python

To ensure a newly created virtual machine has network access you must create and attach a virtual NIC.

Example 4.12. Creating a virtual machine NIC using Python

This Python example creates an NIC named nic1 and attaches it to the virtual machine named vm1. The NIC in this example:
  • Must be a virtio network device. 
    ​nic_interface = "virtio"
  • Must be linked to the rhevm management network. 
    ​nic_network = api.networks.get(name="rhevm")
These options are combined into an NIC parameter object, before using the add method of the virtual machine's nics collection to create the NIC. 
​from ovirtsdk.api import API
​from ovirtsdk.xml import params
​
​try:
​    api = API (url="HOST",
​               username="USER", 
​               password="PASS",
​               ca_file="ca.crt")
​
​    vm = api.vms.get(name="vm1")
​
​    nic_name = "nic1"
​    nic_interface = "virtio"
​    nic_network = api.networks.get(name="rhevm")
​
​    nic_params = params.NIC(name=nic_name, interface=nic_interface, network=nic_network)
​
​    try:
​        nic = vm.nics.add(nic_params)
​        print "Network interface '%s' added to '%s'." % (nic.get_name(), vm.get_name())
​    except Exception as ex:
​        print "Adding network interface to '%s' failed: %s" % (vm.get_name(), ex)
​
​    api.disconnect()
​              
​except Exception as ex:
​    print "Unexpected error: %s" % ex
If the add request is successful then the script will output: 
Network interface 'nic1' added to 'vm1'.
