[ovirt-users] ovirt 3.6 python sdk how to find logical network from a host nic?

[Huan He (huhe)]

Hi Juan,

Thanks! It works. 

One more question, do you know how to do ³save network configuration² in
the api? I did the following

Params.Action(force=1, check_connectivity=1, host_nics=host_nics)

but the gui says the network configuration is not saved. I can¹t find any
relevant params in the Action.

Thanks,
Huan
