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.
