Hi Anil,

as Livnat said, ;vdsmdummy; is required for operation of vdsm, concretely
for changing the link state of a vnic to disconnected. As for the bonds,
they are not created on systemd distros Fedora18+ but they are indeed created
on older distros for backwards compatibility reasons.

Best,

Toni
