Re: [ovirt-users] How to setup OVS using python SDK ?

Hi, Thanks for providing script it is working fine. But it not complete, would you help me to complete step 2 ? https://www.ovirt.org/networking/ovs/ Setup network In the oVirt UI open the 'Setup Host Networks' dialog. Proceed to editing a desired logical network's properties. Among them you will find 'ovs', set it to 'true' or '1' to mark is as a OVS Network. And have one doubt. Why we have to set ovs property two time ?
