[ovirt-users] OVirt SDK python ip problem

[rein]

Hi All,

I have an issue with the python ovirt sdk.
I made a script that creates a new host, hypervisor, in the ovirt environment.
The host is created and is put in maintenance state.
So far it works, but then i try to create the networks on the new host and there i got an error.
