Re: [Users] VDSM n/w issue
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

Hi Anil,
First of all welcome and I hope you'll enjoy working with oVirt.
vdsdummy is a bridge VDSM creates and uses for functionality like
disconnected VNIC.
If you start a VM and you want the VM to have a vNIC not connected to a
specific network (bridge) VDSM starts the VM and connects the tap device
to the vdsdummy bridge. This is a workaround to a functionality we are
missing in libvirt (starting a VM with unconnected tap device).
About the 4 bonds, well that's a legacy code and I think we cleaned this
code in the last version 3.3 - but I'm not sure (Adding Toni to
confirm/disconfirm)
