That's quite logical. Thank you.

You should modify the already existing network_attachment.
Here, since you don't pass the existing attachment 'id', we're trying to create 
a new attachment.
Since you didn't remove the old one, we get two attachments for the same 
network. The old one is still attached to 'eth0', that's why you get the error.

You have to specify the attachment 'id' on the attachment you're updating and 
it should work.

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 :

Very funny, now that my call to /hosts/{host:id}/setupnetworks is better (using 
modified_...), I'm getting an error message. So a totally wrong call throws 
nothing and an almost wrong message return some thing. That is not really 
consistent.

Ok.I got it.

The samples says:  host.nics.setupnetworks(...)
And my code says:  host.setupnetworks(...)

But why does it silently ignore it ? Shouldn't it throw me an error ?

I think I will soon have more questions about what is a modified or removed 
object when creating bond, but I will need to play a little more with it.

The example that you mention describes the old and deprecated

[ovirt-users] configuring bonding on host

2016-05-06 Thread Fabrice Bacchella 
I'm following the example given in http://www.ovirt.org/develop/api/pythonapi/ 
for bonding interfaces.

I'm checking that the network is a plain configuration, exporting 
/api/hosts//nics return :






eth1






none

down

1500
false







eth0







dhcp
100

up

9000
true
false



I send my configuration and get :

> POST /api/hosts/db240f83-9266-4892-a6d2-8ac406cadfb1/setupnetworks HTTP/1.1
...
> my configuration

So every thing is fine, I applied my configuration.
