[ovirt-users] Ovirt remove network from hosted engine

[Abi Askushi]

Hi all,

Just in case ones needs it, in order to remove the secondary network
interface from engine, you can go to:
Virtual Machines -> Hostedengine -> Network Interfaces -> edit -> unplug it
-> confirm -> remove it.

It was simple...
