Hello everybody,
One of the upcoming network features for oVirt 3.4 is Host Network QoS,
i.e. being to configure Quality of Service over networks attached to
hosts' interfaces. The primary motivation is to be able to cap traffic
related to specific networks, so that other networks residing on the
same interface could function. The feature pages are up and I would like
to open the discussion over them.
Overview:
http://www.ovirt.org/Features/Host_Network_QoS
Detailed:
http://www.ovirt.org/Features/Detailed_Host_Network_QoS#Current_Status
I also refer you to a previous thread that discussed an earlier
iteration of this feature a few months ago:
http://lists.ovirt.org/pipermail/arch/2013-July/001502.html
Yours, Lior.

Hi,
I have two thoughts on QoS:
First: You mention just QoS for VMs, Hosts and in the future DCs, what
about Cluster level QoS?
Second: It would also be very useful to track some statistics, like
traffic consumed per vm / host, e.g. for accounting, maybe the
ceilometer project from openstack could provide some of this
information?
What do you think?

Hi Sven,
Thanks for your input, see response below.

Good point. Cluster level would be similar in implementation to DC level
(and might be as useful), the point being that both are relatively
complex and out of the scope of this current feature. I'll update the
feature page to mention the cluster level as well.
Second: It would also be very useful to track some statistics, like
traffic consumed per vm / host, e.g. for accounting, maybe the

It might be useful to integrate with Ceilometer, oVirt will definitely
try to leverage OpenStack wherever possible. Specifically for the
billing use case (which relates more to VM QoS than to host QoS), maybe
someone who knows more about SLA than me would care to comment.
What do you think?

The user-level description of the feature looks great to me! I can't
reallyspeak to the design, but the goal of per-network bandwidth quotas
is an awesome feature.
Cheers,
Dave.

Thanks, the congestion of the management network traffic is a common
pain-point related to live migration in oVirt. The feature aims to
provide a solution, and in a way that should allow users with existing
pre-3.4 DCs to cap the traffic of a single network on all their hosts
within one simple operation.
Cheers,
Dave.
