[Users] ovirt 3.3 vnic profile with bonding & vlans problem

[Sven Kieske]

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.
