[Users] bonding setup with python sdk

[Louis Coilliot]

Hello,  thanks for your feedback.

The version is : rhevm-sdk-3.1.0.16-1.el6ev.noarch and latest from RHN.

About the nullify with or without params.Network() : this was from
Moti's blog example. I changed it with :

nic0 = params.HostNIC(name = 'eth0', network = params.Network(),
boot_protocol='none', ip=params.IP(address='', netmask='',
gateway=''))
nic1 = params.HostNIC(name = 'eth4', network = params.Network(),
boot_protocol='none', ip=params.IP(address='', netmask='',
gateway=''))

Same error message.

The NICS exist on the host :
# ip a | grep eth[0-9]
2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc mq
state UP qlen 1000
3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
5: eth3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
6: eth4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
7: eth5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000
8: eth6: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
9: eth7: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000

The rhevm network exists before applying the script :
# ip a | grep rhevm
21: rhevm: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UNKNOWN
    inet 10.0.1.212/24 brd 10.0.1.255 scope global rhevm
