Ok, I started to play with the right setupnetworks, and I'm getting strange results. When I try to transform an eth0 attachement to a bond attachement, I get Cannot setup Networks. Network Interface 'eth0' cannot become slave, there's network 'ovirtmgmt' attached to it. I tried to have a look at the command that the UI send and don't get it. It says : networks='[HostNetwork:{defaultRoute='true', bonding='true', networkName='ovirtmgmt', nicName='bond0', vlan='null', mtu='9000', vmNetwork='true', stp='false', properties='[]', bootProtocol='DHCP', address='null', netmask='null', gateway='null'}]', removedNetworks='[]', bonds='[Bond:{id='ffcfe313-7607-4347-b797-aa9c3260e221', name='bond0', vdsId='null', networkName='ovirtmgmt', bootProtocol='DHCP', address='null', subnet='null', gateway='null', mtu='9000', bridged='true', type='2', networkImplementationDetails='null', qos='null', macAddress='null', bondOptions='mode=4 miimon=100', labels='null', slaves='[eth0, eth1]'}]', removedBonds='[Bond:{id='ffcfe313-7607-4347-b797-aa9c3260e221', name='bond0', vdsId='null', networkName='ovirtmgmt', bootProtocol='DHCP', address='null', subnet='null', gateway='null', mtu='9000', bridged='true', type='2', networkImplementationDetails='null', qos='null', macAddress='null', bondOptions='mode=4 miimon=100', labels='null', slaves='[eth0, eth1]'}]'}), What I'm doing is quite close, there is a modified network and modified bond. But what about the removedBonds ? They was no bonding before that My code is : bond_name = kwargs['bond_name'] mtu = kwargs.pop('mtu', None) nics = [] for if_name in kwargs['interfaces']: nic = params.HostNIC(name=if_name) if mtu is not None: nic.set_mtu(mtu) nics.append(nic) bonding = params.Bonding( slaves=params.Slaves(host_nic=nics), options=params.Options( option=map(lambda (x, y): params.Option(name=x, value=y), kwargs.pop('bond_options', {}).iteritems() ) ) ) bonded_if = params.HostNIC(name=bond_name, bonding=bonding) if mtu is not None: bonded_if.set_mtu(mtu) ip = kwargs.pop('ip', None) gateway = kwargs.pop('gateway', None) if ip is not None: ip = unicode(ip) ip_addr = ipaddress.ip_address(ip.split('/')[0]) ip_net = ipaddress.ip_network(ip, strict=False) ip_conf = params.IP(address=str(ip_addr), netmask=str(ip_net).split('/')[0]) if gateway is not None: ip_conf.set_gateway(gateway) ip_assignment = params.IpAddressAssignment(assignment_method="static", ip=ip_conf) elif kwargs.pop('dhcp', False): ip_assignment = params.IpAddressAssignment(assignment_method="dhcp", ip=params.IP()) bonded_network = params.NetworkAttachment(network=params.Network(name=kwargs['network']), host_nic=params.HostNIC(name=bond_name), ip_address_assignments=params.IpAddressAssignments([ip_assignment])) return self.broker.setupnetworks(params.Action(modified_bonds = params.HostNics(host_nic = [bonded_if]), modified_network_attachments = params.NetworkAttachments(network_attachment=[bonded_network]), ) ) And it generates : > POST /api/hosts/db240f83-9266-4892-a6d2-8ac406cadfb1/setupnetworks HTTP/1.1 > <action> > <modified_network_attachments> > <network_attachment>
