hmz.... pressed sent by accident
What I want to say is:
Now I got the message that my network is out-of-sync. How can i force
within the ovirt-shell that it syncs the networks?
Because when I press "Sync All Networks" the IP address disappears....
But when I check the box "Sync Network" within the VLAN602 options it
gets pushed to the host.
Is there a difference between the both? And how do I run both via
ovirt-shell?
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

curl \

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@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()
