[ovirt-users] Ovirt remove network from hosted engine

[Abi Askushi]

Hi Knarra,

The ISO domain is of type gluster though I had nfs enabled on that volume.
I will disable the nfs and try. Though in order to try I need first to
remove that second interface from engine.
Is there a way I can remove the secondary storage network interface from
the engine?

Thanx
