[Users] HostNic Addition with IP Address

[Rahul Upadhyaya]

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
2393, in add*
*    body=ParseHelper.toXml(hostnic))*
*  File
"/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/proxy.py", line
117, in add*
*    return self.request('POST', url, body, headers)*
*  File
"/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/proxy.py", line
128, in request*
*    last=last)*
*  File
"/usr/lib/python2.6/site-packages/ovirtsdk/infrastructure/proxy.py", line
154, in __doRequest*
*    raise RequestError, response*
*ovirtsdk.infrastructure.errors.RequestError:*
*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.
