The "sync network" operation is not supported by ovirt-shell.

If you want to set the network configuration, and make it persistent,
then you will need to use one of the "setupNetworks" operations. These
aren't fully usable with ovirt-shell either, so if you want to use it
you will need to use directly the API or one of the SDKs. For example,
lets assume that you have a host with network interfaces eth0, eth1, and
eth2, and that you want to configure eth1 and eth2 as a bond, to put
your VLAN and IP address on top. You can do that with a script like this:

---8<---
#!/bin/sh -ex

url="https://engine.example.com/ovirt-engine/api"
user="admin at internal"
password="..."

curl \
--verbose \
--cacert /etc/pki/ovirt-engine/ca.pem \
--user "${user}:${password}" \
--request POST \
--header "Content-Type: application/xml" \
--header "Accept: application/xml" \
--data '

        <name>bond0</name>
      </host_nic>
      <ip_address_assignments>
        <assignment_method>static</assignment_method>
        <ip_address_assignment>
          <ip netmask="255.255.255.0" address="10.10.10.10"/>
        </ip_address_assignment>

        </options>

            <name>eth2</name>
          </host_nic>

If you prefer to use one of the SDKs, the Python SDK for example, then
it should look like this:

---8<---
#!/usr/bin/python

from ovirtsdk.api import API
from ovirtsdk.xml import params

# Connect to the server:
api = API(
    url="https://engine.example.com/ovirt-engine/api",
    username="admin at internal",
    password="...",
    ca_file="/etc/pki/ovirt-engine/ca.pem",
    debug=True
)

# Find the host:
host = api.hosts.get(name="myhost")

# Set up the networks:
host.setupnetworks(
  params.Action(
    modified_bonds=params.HostNics(
      host_nic=[
        params.HostNIC(
          name="bond0",
          bonding=params.Bonding(
            options=params.Options(
              option=[
                params.Option(name="mode", value="4"),
                params.Option(name="miimon", value="100"),
              ],
            ),
            slaves=params.Slaves(
              host_nic=[
                params.HostNIC(name="eth1"),
                params.HostNIC(name="eth2"),
              ],
            ),
          ),
        ),
      ],
    ),
    modified_network_attachments=params.NetworkAttachments(
      network_attachment=[
        params.NetworkAttachment(
          network=params.Network(name="VLAN602"),
          host_nic=params.HostNIC(name="bond0"),
          ip_address_assignments=params.IpAddressAssignments(
            ip_address_assignment=[
              params.IpAddressAssignment(
                assignment_method="static",
                ip=params.IP(
                  address="10.10.10.10",
                  netmask="255.255.255.0",
                ),
              ),
            ],
          ),
        ),
      ],
    ),
  ),
)

# Close the connection:
api.disconnect()
