Re: [Users] HostNic Addition with IP Address

9 Jul 2012

      Hi Micheal,

After updating the sdk I see change in documentation for hostnic addition
and see bonding as a optional parameter, but I dont see it behaving it that
way. When I try running the code to create and add NIC with Static IP
assigned, I am facing same error where it is asking for bonding parameter
and failing due to the same.

Also, I made sure I removed the previous sdk and ensured my program is
using the latest sdk.

The error that I get is mentioned below :

*Traceback (most recent call last):*
*  File "rtest.py", line 51, in <module>*
*    host.nics.add(params.HostNIC(name = new_hostnic_name, network=network,
boot_protocol = 'static', ip= new_ip))*
*  File
"/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/brokers.py", line

*    body=ParseHelper.toXml(hostnic))*

117, in add*
*    return self.request('POST', url, body, headers)*
*  File
"/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/proxy.py", line

*status: 400*
*reason: Bad Request*
*detail: HostNIC [bonding.slaves.id|name] required for add*
*
*
*
*
The piece of code that I am using to do this is :

*hostid = 0*
*address = ip_start*
*new_hostnic_name = 'em3.'+str(vlanId)*
*for host in hosts :*
*    if host.cluster.id == cluster.id :*
*        hostid = hostid + 1*
*        add_splits = address.split('.')*
*        add_splits[3] = str(200 + hostid)*
*        address= '.'.join(add_splits)*
*        new_ip = params.IP(address = address , netmask = '255.255.255.0' )*
*        host.nics.add(params.HostNIC(name = new_hostnic_name,
network=network, boot_protocol = 'static', ip= new_ip))*
*
*
*        host.commitnetconfig()*
*
*

My requirement is that I do not want to using bonding while addition of a
new NIC to the host, Also , I want to add the ip address to the new NIC at
the time of creation itself.

Regards,
Rahul.

Thanks Michael,
I had a older version of the python-binding which had bonding in #1 as
a compulsory parameter... Seeing your options I updated the sdk and now the
error is resolved. I see bonding as an optional param.

Hi Rahul,
#1 is the right place for doing this, see method __doc__ [1]
#2 used for attaching network to NIC, see __doc__ is [2]
* note all methods in sdk well documented describing what
parameters-holder to use and how to fill it.

Hi Folks,
I am facing issues while adding NIC with Static I.P. to
host using the oVirt Python-Bindings. There are two api's
1) HostNics.add :Here it requires binding param for
interface bonding as a compulsory param. I dont want to bond more than one
interfaces for a network
while creating network each time.
2) HostNic.attach: This lets me attach the NIC but
does not let me put static IP address to it as soon as I add it. I am using
a workaround of updating
the NIC with the IP information, but it requires me to put all the hosts
on maintenance and shut-down all the running VMs which again is not the
best way of doing it.
Is it not supported by the API that at the time of addition of the
hostNIC we can specify the IP address or is it something that I am missing ?
Also,I see that this operation is supported from the manager UI .
