[Users] Host Network QoS feature
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? Am 25.11.2013 07:43, schrieb Lior Vernia:

Hi Sven, Thanks for your input, see response below. On 25/11/13 10:59, Sven Kieske wrote:
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.
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.

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.

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.
