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

Well, yes. That's actually the name VMware uses.

If it bring similar functionalities then that's the solution. Thanks for 
sharing. looks pretty intresting.

Perhaps is the case of contacting the maintainer of Linux Bond module 
and see if there is room for this feature to be implement anytime. 
OVS is great in the coming future, but Bond module is still something 
very handy that simplify the things a lot.

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

Hello Fernando,

As you mentioned, oVirt is using the Linux Bond and the solution you 
are looking for is not supported.
The oVirt way to handle this is by applying QoS on the networks, 
providing the guaranteed rates for each and utilizing the bond for 
throughput beyond the one link limit.


With the introduction of OVS as an alternative networking 
infrastructure for the hosts, you could create a hook that 
implements some special functionality, but ovs is not in yet.


Thanks,
Edy.
