3.11. Creating a vNIC To ensure that a newly created virtual machine has network access you must create and attach a vNIC. This Ruby example creates a vNIC and attaches it to an existing virtual machine, myvm . # Find the root of the tree of services: system_service = connection.system_service # Find the virtual machine: vms_service = system_service.vms_service vm = vms_service.list(search: 'name=myvm').first # In order to specify the network that the new NIC will be connected to, you must # specify the identifier of the vNIC profile. However, there may be multiple # profiles with the same name (for different data centers, for example), so first # you must find the networks that are available in the cluster that the # virtual machine belongs to. cluster = connection.follow_link(vm.cluster) networks = connection.follow_link(cluster.networks) network_ids = networks.map(&:id) # Now that you know what networks are available in the cluster, you can select a # vNIC profile that corresponds to one of those networks, and has the # name that you want to use. The system automatically creates a vNIC # profile for each network, with the same name as the network. profiles_service = system_service.vnic_profiles_service profiles = profiles_service.list profile = profiles.detect { |p| network_ids.include?(p.network.id) && p.name == 'myprofile' } # Locate the service that manages the network interface cards collection of the # virtual machine: nics_service = vms_service.vm_service(vm.id).nics_service # Add the new network interface card: nics_service.add( OvirtSDK4::Nic.new( name: 'mynic', description: 'My network interface card', vnic_profile: { id: profile.id } ) ) For more information, see http://www.rubydoc.info/gems/ovirt-engine-sdk/OvirtSDK4/VmsService:add .
