Hi Sven, disclaimer, not familiar with this feature that much (although I should), looks like the problem is in libvirt (according to your story). googling 'outbound libvirt not working' shows that you're not the only one :) http://www.redhat.com/archives/libvir-list/2011-August/msg00341.html http://www.redhat.com/archives/libvir-list/2012-June/msg01306.html Thanks, Gilad. ----- Original Message -----

Hi,
I am attempting a little test with vnic profiles.
I got a profile named "100mbit" with average: 100 peak: 100 burst: 0
(ovirt warns you can't set peak below average which is not true from libvirt perspective, it is an optional field) I attached this profile to a logical network with a vlan id, which is connected to one vm.
when I start the vm, I see the correct information in the libvirtxml:
<interface type='bridge'> <mac address='MY_MAC'/> <source bridge='MY_BRIDGE'/> <target dev='vnet0'/> <model type='virtio'/> <filterref filter='vdsm-no-mac-spoofing'/> <link state='up'/> <bandwidth> <inbound average='12800' peak='12800'/> <outbound average='12800' peak='12800'/> </bandwidth>
However when I test the download and upload speed inside this vm, just the download (inbound) gets limited correctly, here is a sample test:
Upload (too fast for 100mbit):

This is a CentOS based VM-Host with the following versions:
rpm -qa | grep vdsm vdsm-4.13.3-3.el6.x86_64 vdsm-python-4.13.3-3.el6.x86_64 vdsm-xmlrpc-4.13.3-3.el6.noarch vdsm-cli-4.13.3-3.el6.noarch
rpm -qa | grep libvirt libvirt-client-0.10.2-29.el6_5.3.x86_64 libvirt-lock-sanlock-0.10.2-29.el6_5.3.x86_64 libvirt-python-0.10.2-29.el6_5.3.x86_64 libvirt-0.10.2-29.el6_5.3.x86_64
ovirt engine 3.3.3-2.el6
I triple checked the libvirt xml, it looks correct. it also works for downloads, but not for uploads.
The network setup is as following:
eth0 and eth1 -> bond0 -> bond0.X (vlan) -> vm_net
According to http://www.ovirt.org/Features/Network_QoS#VDSM
libvirt version 1.0.1 or higher is needed, but this can't be true because of 2 things:
1. it works for downloads 2. http://libvirt.org/formatnetwork.html#elementQoS states: "The <bandwidth> element allows setting quality of service for a particular network (since 0.9.4)"
Any help would be greatly appreciated.
Could this be related to bonding? I'm pretty sure this worked before I bonded eth0 and eth1.
