[ovirt-users] Network redundancy with Manual balancing per VLAN

[Yevgeny Zaspitsky]

Dan, Edy,

Could you guys answer this?

IIUC, the requirements are:

   - stream the traffic of few VLANs(network roles) through a single bond
   - be able to bind a VLAN to a bond slave with an option of fallback
   - have redundancy
   - assign different QoS to every VLAN (my addition)

I guess this is a new RFC that we do not support currently, but would we be
able to provide in any future?

Hello,

In VMware it is possible to bond two network interfaces and for each
Portgroup (equivalent to a VLAN) is possible to tell which of the physical
interfaces underneath it you wish the traffic to flow primarily and which
stays as secondary(bond mode=1 equivalent). So for certain VLANs
(Management, Live Migration, etc) is possible to force traffic flow via one
physical NIC of the bond and for other VLANs (Virtual Machine's traffic)
outs via the other NIC with failover to each other should a cable or switch
fails.

This is specially good for better utilize the fewer NICs available and
still have redundancy.

In oVirt it is also possible to have bonds, but would it still be possible
to do that same and favor the traffic per VLAN basis ? I guess it is
something related to Linux Bond module but perhaps someone has done this
already.

Thanks

Fernando
